Abstract

Provided is a cooling treatment system of molten slag which enables a mass treatment of molten slag without causing damage to a cooling drum due to the drop load of molten slag, and can facilitate handling and post-treatment of cooling treated slag. The cooling treatment system of molten slag comprises a single rotatable horizontal cooling drum (1) which cools molten slag by sticking the molten slag to the outer circumferential drum surface (100), and a gutter (2) for supplying molten slag to the horizontal cooling drum (1), wherein the slag cooled while sticking to the drum surface (100) is separated therefrom as the horizontal cooling drum (1) rotates and discharged in one direction. Since the molten slag is poured through the gutter (2), the drop load of molten slag is not applied to the cooling drum (1), and, since the cooling treated slag is discharged in one direction, handling and post-treatment of cooling treated slag are facilitated.

200951098 六、發明說明： 【發明所屬之技術領域】 本發明係關於冷卻滚筒式之熔化溶潰冷卻處理裝置，以及 使用該裝置的熔化熔渣之冷卻處理方法暨熔渣製品之製造 方法。 【先前技術】 在鐵鋼製造製程所產生的熔化熔渣（例如製鋼熔渣），大多 ❹ 係在冷卻場放冷後，再施行灑水而冷卻。此外，亦有採行將 其中一部分流入至通稱「盤冷卻式」的鐵製容器中並施行灑 水冷卻的方法。 另方面用於對咼爐熔》查、垃圾焚化灰炼化熔渣等炼化 溶潰施行冷卻處理的裝置，已知有雙滾筒式之錢冷卻處理 裝置（例:it專利第3613106號公報等）。該炼渣冷卻處理裝置 係具備有於水平方向上並排、且具有相對向之外周部分朝上 疋轉之㈣方向的丨對冷卻滾筒’從上方供應熔化熔渣至該 • 1對冷部滾筒的上部外周面間，㈣成熔潰液滞留。藉由從 _渣液滞留附著•凝固於旋射的冷卻滾筒表面上，而將 熔化溶廣夾帶出，該熔化溶逢係在附著於冷卻滾筒面的狀熊 二冷卻至適度凝固狀態後，再於既定滾筒旋轉位置處，： 用自重而從冷卻滾筒面上剝離，並由回收手段回收。 藉由利用此種冷卻處理裝置對熔化_施行冷卻處理，且 述優點：⑴^需要如習知㈣大冷卻場；（ii)可獲得 098108889 3 200951098 厚度較小的熔渣凝固體，因此可輕易加工為所需粒度的土木 材料、粗骨材等，且在施行破碎處理而製造粒狀熔渣時，粉 末或細粒品產生量較少，因而提升製品良率；（iii)不需要 用於施行冷卻用的灑水、或依較少灑水量便可，因而能獲得 未含水分或水分量較少的熔逢，在供於水泥原料等情況時不 需要乾燥處理等。 但疋’如上述的雙滾筒式之溶渔冷卻處理裝置’因為從1 對冷卻滾筒朝各自相反方向排出處理完之熔渣’因而冷卻處 理完之溶渣的排出/處理需要2路徑，導致需要寬廣的場地 面積。所以，冷卻處理完之熔渣的處置、後處理、熱回收均 較為煩雜，且效率差、設備成本亦會增加。 以冷卻滾筒式之冷卻處理裝置施行冷卻處理的熔渣尚具 有相當的顯熱，所以，從能量有效利用的觀點而言，若欲盡 可能地回收熔渣顯熱，則重要的是從該經冷卻處理之熔渣中 施行熱回收。但是，如習知雙滾筒式之溶渣冷卻處理裝置， 若欲將朝正反二方向排出的冷卻處理完之熔渣，利用1個熱 回收設備施行處理’則在將2路徑整合為1個的搬送過程中 炼潰溫度會降低，無法施行有效率的熱回收。此情形特別係 在大量處理熔化熔渣時將造成大問題。 再者，使用大型雙滚筒式之熔渣冷卻處理裝置，大量處理 溶化溶潰時（例如熔潰處理量：lt/min以上），當從溶渣銷 朝冷卻滾筒灌注熔化熔渣時，有因落下的熔化熔渣荷重導致 098108889 4 200951098 冷卻滾筒遭受損耗之虞。為防止此現象，便必需在冷卻滾筒 上方設置澆口盤，先將熔渣鍋的熔化熔渣暫時移至澆〇盤， 再從該澆口盤施行灌注至冷卻滚筒。但是，當熔化熔渣的灌 注係使用澆口盤的情況，不同於熔融金屬，熔渣會凝固附著 於澆口，導致無法適當地施行灌注等而容易對操作構成障 礙。此外，在澆口盤内殘留/附著的熔渣量亦變多’容易發 生灌注口阻塞、殘留熔渣之粉化等問題。另一方面’為了不 e 致發生此種殘留·附著熔渣情形，便必需設置澆口盤加熱 器，而導致發生能量效率降低、處理成本上升等問題。 當製造高爐熔渣等偏向骨材的熔渣製品時，依照製造條件 會成為非晶質（玻璃質）熔渣，但非晶質熔渣的吸濕性低，容 易出現尖角部分，因而造成問題。此外，當發生纖維狀熔造 的情況，則屬於不適用為偏向骨材製品的形狀。且，若成為 細微纖維狀，則有必需採取包括防止飛散等環境對策的問 ❿ 題。 再者，依照本發明者等人的檢討結果，判斷習知雙滾筒式 之溶潰冷卻處理裝置尚有如下述問題： ⑷如轉爐脫碳精煉炫逢般驗度[質量tb:%Ca〇/%Si〇2](以 下簡稱「鹼度」）較高的炫化溶渣，黏性較高，將此種黏性 較高的溶化熔渣，利用習知雙滾筒式之溶潰冷卻處理裝置施 灯令卻處理時’會因為高黏性，導致熔化熔料易均勻附著 於冷卻滾筒面上，造成滾筒面整體無法有效地使用於冷卻處 098108889 5

Field of the Invention The present invention relates to a cooling drum type melting and melting cooling treatment apparatus, a cooling treatment method using the molten slag of the apparatus, and a manufacturing method of the slag product. [Prior Art] Most of the molten slag (for example, steel slag) produced in the iron and steel manufacturing process is cooled by cooling water after cooling in the cooling field. In addition, some of them have been introduced into an iron container known as a "disc cooling type" and subjected to sprinkling cooling. In another aspect, a device for performing a cooling treatment such as a melting furnace, a waste incineration ash refining slag, or the like is known, and a double drum type money cooling processing device is known (for example: it patent No. 3613106) ). The slag-cooling treatment apparatus is provided with 丨-to-cooling drums that are arranged side by side in the horizontal direction and have a direction toward the upper peripheral portion (fourth direction), and the molten slag is supplied from above to the pair of cold-rolled drums. Between the upper outer peripheral surface, (4) the molten metal is retained. By entraining from the slag liquid and solidifying on the surface of the cooling cooling drum, the molten smelt is entrained, and the molten smelt is cooled to a moderately solidified state after being attached to the surface of the cooling drum. At the position of the rotating position of the drum, it is peeled off from the surface of the cooling drum by its own weight and recovered by recycling means. The cooling treatment is performed by using such a cooling treatment device, and the advantages are as follows: (1) requires a large cooling field as in the conventional (4); (ii) a slag solidified body having a small thickness of 098108889 3 200951098 can be obtained, so that it can be easily Processed into civil materials, coarse aggregates, etc. of the required particle size, and when the granular slag is produced by the crushing treatment, the amount of powder or fine granules is less, thereby improving the yield of the product; (iii) not required for The sprinkling water for cooling or the amount of water sprinkling can be performed, so that a melting point having no water content or a small amount of water can be obtained, and drying treatment or the like is not required when it is supplied to a cement raw material or the like. However, the above-mentioned double-drum type solvent-cooling treatment device "removes the processed slag from the pair of cooling drums in opposite directions", so that the slag discharge/treatment of the cooled processing requires 2 paths, resulting in the need Wide site area. Therefore, the disposal, post-treatment, and heat recovery of the slag after cooling treatment are both cumbersome, and the efficiency is poor and the equipment cost is also increased. The slag subjected to the cooling treatment by the cooling drum type cooling treatment device has a considerable sensible heat. Therefore, from the viewpoint of efficient use of energy, if it is desired to recover the sensible heat of the slag as much as possible, it is important from the Heat recovery is performed in the slag cooled. However, in the case of the conventional double-drum type slag cooling treatment device, if the slag which has been cooled and discharged in the forward and reverse directions is to be treated by one heat recovery device, the two paths are integrated into one. The refining temperature during the transfer process is reduced, and efficient heat recovery cannot be performed. This situation is particularly problematic in the large amount of processing of molten slag. Furthermore, when a large double-drum type slag cooling treatment device is used, a large amount of processing is dissolved and melted (for example, a melting treatment amount: lt/min or more), and when molten slag is poured from the slag pin toward the cooling drum, there is a cause The falling molten slag load causes 098108889 4 200951098 to cool the cooling drum. In order to prevent this, it is necessary to provide a tundish above the cooling drum, and the molten slag of the slag pot is temporarily moved to the pouring tray, and then poured into the cooling drum from the pouring tray. However, when the molten slag is poured using a tundish, unlike the molten metal, the slag is solidified and adhered to the gate, resulting in failure to properly perform the perfusion or the like, which may easily hinder the operation. Further, the amount of slag remaining/attached in the tundish is also increased, and problems such as clogging of the perfusion port and pulverization of residual slag are likely to occur. On the other hand, in order to prevent such residual and adhering slag from occurring, it is necessary to provide a tundish heater, which causes problems such as a decrease in energy efficiency and an increase in processing cost. When a slag product such as blast furnace slag or the like is produced, it becomes amorphous (glassy) slag according to the production conditions, but the amorphous slag has low hygroscopicity and is prone to sharp corners, thereby causing problem. Further, in the case where fibrous melting occurs, it is not suitable as a shape that biases the aggregate product. Further, if it is in the form of fine fibers, it is necessary to take measures such as environmental measures such as prevention of scattering. Further, according to the results of the review by the inventors of the present invention, it is judged that the conventional double-drum type smelting-cooling treatment apparatus has the following problems: (4) If the converter decarburization refines the brightness and the like degree [mass tb: % Ca 〇 / %Si〇2] (hereinafter referred to as "alkalinity") is a high-density slag with high viscosity. This kind of viscous slag with high viscosity is made of a conventional double-drum type melting and cooling treatment device. When the lamp is applied, it will be treated because of the high viscosity, so that the molten melt tends to adhere uniformly to the surface of the cooling drum, so that the entire drum surface cannot be effectively used in the cooling zone 098108889 5 200951098.

And a rotatable single horizontal cooling drum 1 (hereinafter referred to as "the cooling drum Ijo is the same as other embodiments"; and a barrel 2 for supplying the molten slag to the cooling drum 1. Here, the horizontal type of the horizontal cooling drum The rotation axis of the drum is substantially horizontal. The barrel 2 is disposed on one side of the radial direction of the cooling drum, and supplies molten slag s to the upper drum surface of the cooling drum 1 from an appropriate temperature. The upstream side of the crucible 2 is supplied with molten slag s from a slag pot or the like. The form of the tub 2 is arbitrary, and by using a sufficient width in the width direction of the cooling drum (the direction of the drum shaft), the molten slag can be made The direction of the width of the drum is enlarged, and the molten slag can be uniformly cooled by the drum surface 100. The cooling drum 1 is rotationally driven by a driving device (not shown) so as to rotate in the direction of the counter drum in the direction of the upper drum. After the molten slag S supplied to the drum surface 1 is attached to the drum surface 1 and cooled, it is peeled off from the drum surface 100 as the cooling drum 1 is twisted, and is discharged to the radial direction side of the cooling drum. In addition, the cooling drum 1 is preferably capable of controlling the number of revolutions in accordance with the operating conditions. The internal cooling of the cooling (4) 1 is provided in the flow path f for the passage of the refrigerant. The cooling mechanism (not shown) is at each end portion of the drum shaft.

Further, the conveying speed of the conveying conveyor 8 is substantially the same as the peripheral speed of the cooling drum 1. In the cooling treatment of the molten slag S as described above, since the slag Sx cooled and discharged from the drum surface 1 of the single cooling drum 1 is discharged in one direction, the treatment and post-treatment of the slag after the cooling treatment is completed. It is easier to wait. Therefore, when sensible heat recovery is performed from the cooled slag Sx, heat recovery can be efficiently performed by one heat recovery device. Further, since a large drop load is not applied to the cooling drum 1 by melting the slag slag, the molten slag s can be processed in a large amount without losing the cooling drum 1. Cooling is supplied to the inside of the pulverizing tank 9 and cooling is performed. Further, the cooling of the slag Sx peeled off from the cooling drum 1 can be carried out by other means or places. The cooled slag Sx is supplied to the steps for the crushing treatment and/or the grinding treatment for forming the slag product, and is subjected to sizing by sieving or the like as necessary. In general, the slag Sx which has just been cooled by the cooling drum 1 is in a moderately solidified state as described above, because it is peeled off from the surface of the cooling drum because of its plasticity, and the slag Sx system is collected by the conveying conveyor belt 8. It is a plate-like continuum. However, depending on the thickness of the slag Sx and the degree of solidification, the continuous body of the plate-shaped slag may be pulverized while being peeled off from the surface of the cooling drum and collected by the conveyance belt 8, but it does not pose a problem. Further, when the slag Sx is transported from the transport conveyor 8 to the tub or the like, the crush Sx may be coarsely crushed by an appropriate means as needed. 098108889 13 200951098 Fig. 2 is a schematic front elevational view showing another embodiment of the cooling treatment apparatus and the cooling treatment method of the molten slag according to the present invention. In the present embodiment, the tub 2 is such that its front end portion is adjacent to or close to the drum surface 100 of the cooling drum 1, and the molten slag S is directly supplied from the front end portion of the tub 2 to the drum surface 100' to be attached to the drum surface. 100. The uranium end of the tub 2 may also be adjacent to the drum surface 1 〇〇, or may form a small gap close to the drum surface 100. In the latter case, it is preferable to consider the thermal expansion or the like to bring the molten slag S into contact with the gap so that the molten slag S does not leak, but in order to surely prevent the molten slag S from leaking, it is preferable that the gap portion is below the simmering 2 The gas injection means 10 provided is sprayed with a forced gas. The gap between the front end portion of the tub and the drum surface 100 varies depending on the viscosity of the molten slag. However, when the solid surface is cured at a high temperature, the H recording is preferably 5 or less, more preferably 3 mm or less, and particularly preferably 1 mm or less. . The narrower the gap, the more the amount of forced gas can be reduced. The gap limit which can suppress the melt-melting (four) leakage in the case of no forced air atmosphere is greatly dependent on the (four) trait (heterogeneous), but if the gap can be set to almost no contact state of 1 liter or less, almost any situation : Even if there is no forced net gas, it can suppress the smelting (4) leakage. Because the narrower the gap, the more the front end of the tub is worn and the loss is caused by the contact, so that the front end of the tub with a high possibility of coming into contact with the drum surface is preferably made of a carbonaceous material having good sliding properties. Or other materials such as nitrite. Among them, the gap value is the value of the actual operation (two temperature state), and when the device is set at the normal temperature, it is necessary to consider the thermal expansion of the cooling drum as described above. The following is an example of thermal expansion - 098108889 200951098. Steel cooling diameter of 1. 6m0 cooling drum 'steel thermal expansion rate ι5χ1 ()-6, when the average temperature of the drum material is 200 ° C 'the length of the thermal expansion in the radial direction becomes a radius of 800mmx200 ° Cxl5xl 〇 -6 = 2. 4mm. Further, since the rest of the configuration of the present embodiment is the same as that shown in Fig. 1, the detailed description is omitted. By using the cooling treatment of the molten slag of the above-described cooling treatment apparatus, since the falling load due to the slag slag S is hardly applied to the cooling drum 1, the loss of the cooling drum 1 can be further alleviated. The figure is a schematic front view showing another embodiment of the cooling treatment apparatus and the cooling treatment method of the molten slag of the present invention. In the present embodiment, the tub 2 is provided such that its front end portion abuts or approaches the drum surface 1'' of the cooling drum 1, and the front end portion of the simmering sill 2 forms a slag liquid retention portion A with the drum surface, with the cooling drum 丨After the rotation, the molten slag s in the slag liquid retention portion A adheres to the drum surface 1 and is taken out. In order to form

並附著於該滾筒面1〇〇上的黏性較高熔化熔渣s，係不易朝 滾筒寬度方向（滾筒轴方向）擴展，因而呈現不均勻地附著在 滾筒寬度方向上的滾筒面100之狀態（局部性附著於冷卻滾 筒面的狀態）。在此狀態下，熔化熔渣s的冷卻效率（=每單 位時間的熔渣散熱量/熔渣單位容積）非常差，且熔渣從冷卻 滚筒1上剝離時的凝固狀態變得不均勻，導致品質發生變 動。本實施形態中，係將如此不均勻附著在滚筒面100的熔

可使用其他流體（液體或氣體）。 另外’因為本實施形態的其餘構造均如同圖3所示實施形 態，因而省略詳細說明。 使用如上述冷卻處理裝置的熔化溶渣之冷卻處理，供應給 盛桶2的熔化熔渣S流入至熔渣液滞留部A中，藉由在此滯 留適當時間而冷卻後，從冷卻滚筒1與堰4(堰體4a)之間的 098108889 20 200951098 開口 5，一邊冷卻一邊擠出。擠出的熔化熔渣S在附著於冷 卻滾筒面的狀態下，經冷卻至適度凝固狀態（例如半凝固狀 態、或者僅單面或雙面表層凝固的狀態）後，便如同圖1〜圖 3的實施形態，在既定滾筒旋轉位置處利用自重從冷卻滾筒 面上自然剝離。 此種炫化熔渣的冷卻處理，係藉由熔化溶渣S在溶潰液滯 留部A内滯留充分時間，而促進冷卻，並在從開口 5中擠出 φ 時亦利用冷卻滾筒1進行冷卻，因而即使充分加大開口 5 寬度（厚度）而擠出厚板熔渣Sx時，仍可將熔化熔渣S適當 地冷卻。因此可從開口 5擠出經適當冷卻且厚度5mm以上的 厚板之板狀熔渣Sx。根據本實施形態，亦可輕易地製造厚 度20〜30丽左右的厚板熔渣凝固體。 另外，圖8所示實施形態中，當堰體4a不具有特別内部 冷卻機構的情況，從開口 5擠出的熔渣Sx，通常係鄰接冷 6 卻滾筒1之侧的下面與二侧端面凝固，而上面侧則呈熔融或 半熔融狀態，但若所擠出之熔渣Sx呈此程度的凝固狀態則 並不會構成問題。 圖9所示係本發明的熔化熔渣之冷卻處理裝置及冷卻處 理方法另一實施形態示意正視圖。本實施形態的冷卻處理裝 置亦在冷卻滾筒1上部設有堰4。 本實施形態中，在冷卻滾筒1上部所設置堰4，係由下部 滚筒面具有朝反熔渣液滯留部A方向旋轉之旋轉方向的冷 098108889 21 200951098 卻滚筒4χ所構成。 如同冷卻滚筒1，在上述冷卻滚筒4χ内部設有具供冷媒 流通用之流路的内部冷卻機構（未圖示），並在滚筒軸的各端 部分別設置對該内部冷卻機構的冷媒供應部與冷媒排出 部。另外，冷媒一般係使用水（冷卻水），但亦可使用其他流 體（液體或氣體）。 如同圖8所示實施形態，開口 5的寬度（厚度）較佳設定為 5mm以上、更佳20mm以上。此外’最好藉由能調整冷卻滾 筒4x的上下方向位置，而改變開口 5的寬度（厚度）。 再者，如同冷卻滚筒1，冷卻滚筒4x亦利用驅動裝置（未 圖示）朝上述旋轉方向旋轉驅動。另外，冷卻滾筒1、與冷 卻滚筒4x亦均最好能配合操業條件而控制旋轉數。另外， 冷卻滾筒4x未必一定要位於冷卻滾筒1的正上方，亦可如 本實施形態般在水平方向上偏移位置。 另外，因為本實施形態的其餘構造均如同圖 態，因而省略詳細說明。 使用如上述冷卻處理裝置的炼化溶渣之冷卻處理，、,、 渣S係藉由在熔渣液滯留部A内滞留適當時間而A卻t… 在冷卻滾筒1 -冷卻滾筒4x之間被軋延的方式，從開口 $ 邊施行冷卻一邊擠出。此時，熔化熔渣因為承受：（丨）在熔 渣液滯留部A内滯留充分時間而冷卻，以及 在開口 5 的進入側與冷卻滚筒1及冷卻滾筒4χ進行長時間接觸後， 098108889 22 200951098 再於開口 5内利用冷卻滾筒1與冷卻滾筒4χ從二側施行乾 延並冷卻；的冷卻作用’因而可更有效地促進熔化熔逢s 的冷卻’可更安定地獲得厚板熔渣凝固體。 另外’本實施形態的冷卻滾筒1、冷卻滚筒4χ、以及圖8 所示實施形態的冷卻滾筒1 ’係屬表面呈平滑的圓筒體，惟 未必僅侷限於此，亦可設有溝等凹凸。若滾筒面1〇〇設有凹 凸，則與熔化溶渣間的接觸面積增加，可促進溶渣的冷卻。 ❿ 此外’亦有凝固的熔渣容易破碎•磨碎的優點。此外，關於 透過冷媒的熱回收，亦因為比表面積較大，因而提高熱交換 效率。 再者’亦可利用在冷卻滾筒1的滾筒面100上所形成之環 狀溝等凹凸，在冷卻滚筒i與冷卻滾筒4χ的滾筒面間形成 孔形狀開口 5 ’炼渣便利用該孔形狀擠出。所以，從冷卻滾 筒1與冷部滾筒4χ間的開口 5所播出之熔渣&的形狀，亦 參可為除板狀之外的線狀或柱狀等。此外，依照冷卻滾筒！ 或冷卻滾筒4x的滾筒面凹凸形狀，會有開口 5呈間歇性形 成，使熔逢Sx的擠出呈不連續的情況，此情況下，係從開 口 5將熔渣Sx實質上依塊形狀擠出。 圖„ 9所示實施形態中’從開口 5擠出的熔渣Sx厚 度’係疋A為知8騎之冷卻滾筒徑方向上祕潰最大厚 f卜：所擠出之熔潰&的形狀係除板狀以外的情況，依 述疋義的料Sx之厚度較佳為5mm以上、更佳2〇腿 098108889 23 200951098 以上。 圖8與圖9所示實施形態中，從開口 5擠出的厚板炼漁 Sx，通常僅單面或雙面表層凝固，而内部則呈熔融或半熔融 狀態。而剛從開口 5擠出後的凝固表層部，係利用冷卻浪请 進行急冷而成為玻璃質或接近其的組織，但爾後藉由内部未 凝固熔渣的熱而回熱，變化為結晶質。所以，該等實施形態 中’可獲得玻璃質較少的厚板熔渣凝固體。 圖10及圖11、圖12及圖13、圖14及圖15、圖16及圖 17、圖18及圖19所示之各實施形態，係從冷卻滚筒1與冷 卻滾筒4x間的開口

圖14與圖15所示實施形態中’圖14所示係冷卻處理裝 置及冷卻處理方法其中一部分的示意正視圖，圖15所示係 侧視圖。本實施形態中，在冷卻滾筒4x的滚筒面400上， 於滚筒長邊方向上相間隔地形成複數環狀溝402，且該等環 狀溝402的底面在滚筒圓周方向上構成為凹凸狀（齒輪 狀），藉由使冷卻滚筒4x的滾筒面400抵接於冷卻滚筒1 的滾筒面100，而利用環狀溝402形成孔形狀之開口 5。本 實施形態中，利用環狀溝402底面的凹部而間歇性地加大開 π 5。 本實施形態中，係從由環狀溝402所形成之複數之孔形狀 開口 5中擠出熔渣Sx。該熔渣Sx係因為利用環狀溝402底 面的凹部而將開口 5呈間歇性地變大，因而依塊狀部b呈串 珠狀連串的形狀擠出。此種形狀的熔渣Sx在從冷卻滾筒1 剝離後，利用自重而分離為塊狀、或利用小外力即輕易地分 離呈塊狀。 本實施形態的其餘構造均如同圖3、圖9所示實施形態， 因而省略詳細說明。 另外，圖15中，省略在環狀溝402底面所形成的凹凸之 圖示，而底面的凸部位置則利用假想線標示。 再者，亦可取代如圖14及圖15的實施形態之環狀溝 402，改為在滾筒圓周方向上相間隔地形成溝狀或孔狀凹 部，此情況，利用該凹部間歇性地形成開口 5，旅從該開口 098108889 26 200951098 5擠出塊狀熔渣Sx。 再者’亦可不在冷卻滾筒4x的滾筒面400上，而是在冷 卻滾筒1的滾筒面100上於滾筒長邊方向上相間隔地形成複 數之％狀溝（或如上述在滾湾圓周方向上相間隔地形成溝狀 或孔狀之凹部）’利用該環狀溝等形成孔形狀開口 5。 圖16及圖17的實施形態中’圖16所示係冷卻處理裝置 及冷卻處理方法其中一部分的示意正視圖，圖17係侧視 Φ 圖。本實施形態中，在冷卻滾筒1的滾筒面100、與冷卻滾

設置朝冷卻滚筒1的下部滾筒面吹抵冷卻用流體的滾筒冷 卻手段。該冷卻手段係例如可由朝冷卻滾筒1的下部滚筒 面，吹抵水或空氣等冷卻用流體的喷嘴等所構成。 再者，在具有冷卻滾筒4x的冷卻處理裝置中，亦可取代 ❿在冷卻滚筒4χ内設置如前述内部冷卻機構、或除了該此種 内部冷卻機構之外，設置朝冷卻滚筒4χ的滚筒面吹抵冷卻 用流體的滾筒冷卻手段。該冷卻手段亦可利用例如朝冷卻滾

液滯留部A内的熔化熔渣溫度調整、（b)熔渣改質、（c)熔化 熔渣的顯熱回收中之1個以上目的下，亦可從該流體供應手 段對熔渣液滯留A内供應氣體等流體。另外’無關該等 (a)〜（c)目的’若對熔渣液滯留部a吹入氣體等流體並將熔 098108889 31 200951098 渣浴施行擾拌，便可促進熔潰的冷卻。 圖20所示係此情況的冷卻處理裝置及冷卻處理方法一實

熔化熔渣的溫度降低。流體係可使用例如：空氣、氮氣、水 蒸氣等。 相關上述（b)的熔渣改質，例如在以減少熔渣中的f-CaO 量為目的時，可使用諸如空氣、富氧化空氣、氧氣等氧或含 098108889 32 200951098 氧氣體*將此種氣體供應給溶化溶潰，則溶潰中的Μ 被氧化’其與f-CaO鍵結而形成2Ca0 · Fe2〇3，因此熔逢中 # f CaO 低’當將所獲得之熔潰凝固體使用於路床料等

流體’並從該流體中執行熱回收。流體係可使用例如：空氣、 氮氣、水蒸氣等。 再者，藉由將水蒸氣（水）、與天然瓦斯或焦炭爐氣體等含 ❹ 烴系成分的氣體，同時供應給熔渣液滯留部Α内，而產生水 蒸氣改質反應，因為對該改質反應的吸熱供應熔渣的顯熱， 因而可促進熔化熔渣的冷卻，且利用反應所生成的氣體（富 氫氣體）可回收當作可燃性氣體、或熱回收。當含烴系成分 氣體係使用例如曱烷氣體的情況’則發生CHAM)—CO+3H2 的反應。 另外，對熔渣液滯留A内的流體供應’亦可適用於未設置 堰4之如圖3所示實施形態。 098108889 33 200951098 再者，具有熔渣液滯留部A的冷卻處理裝置中 渣液滯留部A的熔化熔渣之溫度調整、（b)熔査在（a)熔 依熔渣的破碎或磨碎處理所產生之熔渣粉之再文質、（c) 製品良率中之丨個以上之目的下，可在;;液而提升

固體狀態炼渣進行顯熱回收時，因為熔渣量增加，可縮小固 體溶邊的表面溫度與内部溫度差，因而能有效地進行熱回 收。另外，因為促進熔化熔渣的冷卻•凝固，因而可減輕冷 部滾筒1或拉伸輥3等的熱負荷•熱疲勞。 098108889 34 200951098 上述⑻祕潰改質’係藉由將例如發砂、飛灰等⑽ 高氧磚肩等八12〇3源、氧化鐵粉或鐵镇粉等氧化鐵源 於熔化炼潰，而使炫渣令的卜Ca0量降低，俾可抑制將戶=

Further, the side wall 2' of the front end portion of the tub which forms the slag liquid retention portion A has a predetermined height in order to maintain the molten slag S. Further, since the rest of the configuration of the present embodiment is the same as the embodiment shown in Fig. 1, detailed description is omitted. In the cooling treatment using the molten slag of the above-described cooling treatment apparatus, the molten slag S supplied to the tub 2 is supplied into the slag liquid retention portion A by the supply of 098108889 200951098, and after being cooled for a suitable period of time, it is attached thereto. The drum surface of the cooling drum 1 is taken out, as in the embodiment of FIGS. 1 and 2, and then adhered to the drum surface 100, cooled to a moderately solidified state (for example, semi-solidified state, or only one-sided or double After the surface layer is solidified, it is naturally peeled off from the surface of the cooling drum by its own weight at a predetermined drum turning position. In the present embodiment, since the molten molten metal S stays in the slag liquid retention portion A for a sufficient period of time to promote the cooling, the thick plate slag Sx is easily obtained. 4 to FIG. 6 are schematic views showing another embodiment of the melt-dissolving cooling treatment apparatus and the cooling treatment method of the present invention, and FIG. 4 is a front view, FIG. 5 is a plan view, and FIG. 6 is a cooling drum. An explanatory view of the action of the stretching roller attached thereto. The cooling treatment apparatus according to the present embodiment is provided with a stretching roll 3 for rolling the molten slag S attached to the drum surface 100 of the cooling drum 1 and stretching in the width direction of the drum, and is particularly suitable for high viscosity. Further, the slag basicity [mass ratio: %CaO/%Si〇2] (hereinafter referred to as "basicity") is a cooling treatment of the molten slag of 2 or more. The slag having a basicity of 22 is, for example, a converter steel decarburization refining slag, a dephosphorization slag, an electric furnace slag, a steel slag, a waste gasification melting slag, a waste incineration ash melting slag, and the like. A stretching roller 3 belonging to the slag stretching means is disposed in parallel with the cooling drum 1 at the upper portion ' of the cooling drum 1. The drawing roll 3 is rolled by the molten slag s attached to the drum surface 100 (upper outer peripheral surface) of the cooling drum 1, and is stretched in the width direction of the drum 098108889 16 200951098, according to the outer peripheral surface 300 and the cooling drum 1 The manner in which the predetermined interval t is formed between the drum faces 100 is rotatably supported by the support arm 11. In the present embodiment, 'the upper end (lower end) of the support arm 11 is formed with an elongated circular bearing hole 110 elongated in the vertical direction, and the bearing hole 110 + is slidably supported by the roller shaft 301 of the stretching roller 3.

It is preferable to have a roll 098108889 200951098. Further, the relevant stretching roll 3 preferably has an internal cooling mechanism like the above-described cooling roll 1 from the viewpoint of the cooling efficiency and the durability of the stretching roll. Further, the stretching m may be provided in a plurality of places in the circumferential direction of the cooling drum. The plurality of stretching rolls are applied to the coating of the drum surface by the plurality of stretching rolls 3. Further, since the rest of the configuration of the present embodiment is the same as that shown in Fig. 3, detailed description is omitted. Further, the stretching roll 3 of the present embodiment may be attached to the cooling processing apparatus of the form shown in Figs. 1 and 2 as well. When the viscous slag is cooled by the cooling treatment device as described above, it is carried out from the slag liquid retention portion to the cooling drum and adheres to the nip of the roller surface. The higher melting slag s is not easily spread in the drum width direction (the drum axis direction), and thus exhibits a state in which the drum surface 100 is unevenly attached to the drum width direction (a state in which it is locally adhered to the cooling drum surface). In this state, the cooling efficiency of the molten slag s (= slag heat dissipation per unit time / slag unit volume) is very poor, and the solidified state when the slag is peeled off from the cooling drum 1 becomes uneven, resulting in unevenness Quality has changed. In the present embodiment, the molten slag S which is unevenly adhered to the drum surface 100 is rolled by the stretching rolls 3, and is stretched in the drum width direction. Thereby, the cooling efficiency of the molten slag S can be increased, and the cooling rate of the molten slag S can also be increased. As in the embodiment of Fig. 1 to Fig. 3, the molten slag S is cooled to a moderately solidified state in a state of being attached to the surface of the cooling drum (for example, 098108889 18 200951098 such as a semi-solidified state or a state in which only the surface layer is solidified) The predetermined drum rotation position is naturally peeled off from the cooling drum surface by its own weight. According to this, the refining slag S is stretched in the width direction of the drum by the stretched grain 3, and the thickness of the melted melt S is thinned, and the cooling efficiency of the melt is improved, the productivity is improved, and the slag is smeared. The cooling rate is also increased, so that a slag solidified body which is not easily pulverized can be obtained. Further, a slag solidified body in which the slag solidified state is uniform and uniform in quality can be obtained. Fig. 7 is a schematic plan view showing another embodiment of the cooling treatment apparatus and the cooling treatment method of the molten slag according to the present invention. The cooling treatment apparatus of this embodiment also has a stretching rod 3 belonging to a slag stretching means. In the present embodiment, a plurality of stretching members are disposed on the cooling drum 1. Specifically, the stretching roller 3x is disposed at a central portion in the drum width direction at the upstream side of the cooling drum rotation direction, and the stretching roller 3y is disposed on both sides in the drum width direction at the downstream side of the cooling drum rotation direction. 3z. The rolling range of the stretching rolls 3y, 3z in the width direction of the roll is partially overlapped with the rolling range of the stretching roll 3x in the roll width direction. According to this, by arranging the stretching rolls 3χ to 3Z on the upstream side and the downstream side in the cooling roll if direction, the molten slag S on the cooling roll surface can be sequentially stepwise stretched. As in the present embodiment, since the shorter stretching rolls 3X to 3Z are less curved in the longitudinal direction, it is advantageous to make the rolling thickness of the slag in the width direction of the cooling drum uniform. Further, since the rest of the configuration of the present embodiment is the same as that of the embodiment shown in Figs. 4 to 6, the detailed description is omitted. 098108889 200951098 Fig. 8 is a schematic front elevational view showing another embodiment of the cooling treatment apparatus and the cooling method of the molten slag according to the present invention. In the present embodiment, the tub 2 is disposed such that its front end portion abuts or is adjacent to the drum surface 100 of the cooling drum 1, and is disposed above the cooling drum 利用, and is formed by the front end portion of the drum surface 100 and the tub 2 The slag stagnation I' portion A' forms an opening 5 between the crucible 4 and the cooling drum 1 to extrude the molten slag in the slag liquid retention portion a. The present embodiment is directed to obtaining a slag solidified body having a thickness of 5 mm or more, preferably 2 〇 mm y i . Therefore, the width (thickness) of the opening 5 is preferably set to be more than 20 mm. Further, it is preferable to change the width (thickness) of the opening 5 by adjusting the position of the upper and lower sides of the crucible 4. In the present embodiment, the crucible 4 is composed of a fixed body 4a (wall body) and supported by a device body (base body) via a suitable supporting member.

In this case, a refrigerant supply unit and a refrigerant discharge unit for the internal cooling mechanism are provided. Further, 'refrigerant generally uses water (cooling water), but other fluids (liquid or gas) can also be used. Further, since the rest of the configuration of the present embodiment is the same as that shown in Fig. 3, detailed description is omitted. The cooling slag S supplied to the tub 2 flows into the slag liquid retention portion A by using the cooling treatment of the molten slag as in the above-described cooling treatment device, and after cooling for a suitable period of time, is cooled from the cooling drum 1 098108889 20 200951098 Between the 堰4 (the body 4a), the opening 5 is extruded while cooling. The extruded molten slag S is cooled to a moderately solidified state (for example, a semi-solidified state, or a state in which only one-sided or double-sided surface layer is solidified) in a state of being attached to the surface of the cooling drum, as shown in FIGS. 1 to 3 In the embodiment, the self-weight is naturally peeled off from the surface of the cooling drum at a predetermined drum rotation position. The cooling treatment of the smelting slag is carried out by the molten slag S in the stagnation liquid retention portion A for a sufficient period of time to promote cooling, and is also cooled by the cooling drum 1 when φ is extruded from the opening 5. Therefore, even if the thick plate slag Sx is extruded while sufficiently increasing the width (thickness) of the opening 5, the molten slag S can be appropriately cooled. Therefore, the plate-like slag Sx of the thick plate which is appropriately cooled and has a thickness of 5 mm or more can be extruded from the opening 5. According to this embodiment, it is also possible to easily produce a thick plate slag solidified body having a thickness of about 20 to 30 Å. Further, in the embodiment shown in Fig. 8, when the cartridge 4a does not have a special internal cooling mechanism, the slag Sx extruded from the opening 5 is usually adjacent to the cold 6 but the lower surface of the drum 1 and the two end faces are solidified. While the upper side is in a molten or semi-molten state, it does not pose a problem if the extruded slag Sx is in such a state of solidification. Fig. 9 is a schematic front view showing another embodiment of a cooling treatment apparatus and a cooling treatment method for molten slag according to the present invention.

As in the embodiment shown in Fig. 8, the width (thickness) of the opening 5 is preferably set to 5 mm or more, more preferably 20 mm or more. Further, it is preferable to change the width (thickness) of the opening 5 by adjusting the position of the cooling roller 4x in the up and down direction. Further, like the cooling drum 1, the cooling drum 4x is also rotationally driven in the above-described rotational direction by a driving means (not shown). Further, it is preferable that both the cooling drum 1 and the cooling drum 4x can control the number of rotations in accordance with the operating conditions. Further, the cooling drum 4x does not necessarily have to be located directly above the cooling drum 1, and may be displaced in the horizontal direction as in the present embodiment. Further, since the remaining configurations of the present embodiment are as in the drawings, detailed descriptions thereof will be omitted. By using the cooling treatment of the refining slag as in the above-described cooling treatment apparatus, the slag S is retained in the slag liquid retention portion A for a suitable period of time, but A is between the cooling drum 1 and the cooling drum 4x. The method of rolling is extruded from the opening $ while cooling is performed.

In the heat recovery by the refrigerant, since the slag is larger than the table, the heat exchange efficiency is improved, and efficient heat recovery can be performed. It also has the advantage of not requiring or reducing the slag breaking procedure in subsequent steps. The slag that is extruded from the opening 5 and processed into the slag of the slag is processed by a crushing device such as a crusher, and the shearing device can also be used for cutting. x The cooling treatment device of the present invention is preferably such that the molten slag s is layered on the drum surface 100 of the cold portion j of the rotating portion, and in this state, only the rotation/deactivation 1 is properly rotated. The necessary cooling is performed during the rotation angle. Further, since the molten slag S contacts the cooling drum 1 and is cooled to at least the surface to form a solidified layer, the number of rotations of the cooling drum 1 is preferably about 2 2 〇ΓΡΠ 1 or more, more preferably about 2 to 10 rpm. In this case, the circumferential speed of the drum surface of the cooling drum 1 varies depending on the diameter of the cooling drum 1, and is preferably set to, for example, 〇·1 to 2 m/sec, more preferably 0. Bu lm / sec or so. If the rotational speed of the cooling drum 1 exceeds the above range, the molten slag is less likely to contact/attach to the drum surface 1〇〇. In the case where the peripheral speed of the drum surface is more than 5 m/sec, the molten slag such as blast furnace slag may be broken or finely granulated to form a fibrous shape due to the force received from the drum. Therefore, it is not conducive to the quality of the molten product. On the other hand, when the rotational speed of the cold portion drum 1 is less than the above range, the amount of treatment is reduced to a large amount of processing which is disadvantageous to the slag. In particular, when the thickness of the solidified layer becomes thick and the semi-solidified portion disappears or almost disappears, such as blast furnace smelting, the roll cooling treatment is completed, so that almost == raw (four) After _. Therefore, it is impossible to cause the amorphous layer to disappear in the contact with the roll, resulting in a decrease in suction, and a sharp state of the phase characteristic is disadvantageous to the quality of the slag product. Further, the solidification state of the layer is melted by a stretching roll or the like (4). Since the unevenness of the roll may be caused by the inclusion of the material, it is preferably avoided. In the case of sensible heat of the slag, the proportion of the heat dissipation of the shaft is also increased. Therefore, it is preferable to avoid the 鞔7邯 which is usually performed by the cooling water, and the rise of the cold water temperature is set to about 5, which is difficult to cool. Water for heat recovery). Since it is about 1 〇c, an example of the relationship between the cooling treatment apparatus of the present invention and the amount of material to be processed is shown in Fig. 26. W (the same as the number of (4) 098,108,889] The various embodiments of the above-mentioned various implementations (4) can be described in the line of 200951098. In order to cool the cooling drum 1, it is also possible to provide an internal cooling mechanism as described above in the cooling drum, or to provide a drum that blows the cooling fluid toward the lower drum surface of the cooling drum 1 in addition to the internal cooling mechanism. Cooling means. This cooling means can be constituted, for example, by a nozzle that blows a cooling fluid such as water or air toward the lower drum surface of the cooling drum 1. Further, in the cooling treatment apparatus having the cooling drum 4x, instead of or in addition to the internal cooling mechanism in the cooling drum 4, the drum surface may be blown toward the cooling drum 4χ. A drum cooling means for the cooling fluid. The cooling means may be constituted by, for example, a nozzle that blows a cooling fluid such as water or air toward the drum surface of the cooling drum 4A. Further, as shown in Fig. 1, the slag Sx' which is peeled off from the cooling drum 1 may be provided with a cooling means 7 for cooling between the cooling drum 1 and the conveying conveyor 8, or on the conveying conveyor 8. The cooling means 7 is constituted by, for example, a nozzle that blows a shallow fluid Sx against a cooling fluid such as water or air. The cooling treatment device having the slag liquid retention portion A is provided with a fluid supply means for blowing a fluid into the slag liquid retention portion A, and for example, (a) the molten slag temperature in the slag liquid retention portion A For the purpose of adjusting, (b) slag upgrading, and (c) sensible heat recovery of the molten slag, a fluid such as a gas may be supplied to the slag liquid from the fluid supply means. Further, irrespective of the (a) to (c) purpose, if a fluid such as a gas is blown into the slag liquid retention portion a and the molten 098108889 31 200951098 slag bath is spoiled, the cooling of the melt can be promoted. Fig. 20 is a front elevational view showing a cooling treatment apparatus and a cooling treatment method in this case. In the present embodiment, the fluid blowing means 6 is provided at the bottom of the front end portion of the tub 2 constituting the slag liquid retention portion A, and the fluid is blown from the fluid blowing means 6 into the slag liquid retention portion A. This fluid blowing means 6 is constituted by, for example, a gas injection nozzle or the like. The rest of the structure of the present embodiment is the same as that of the embodiment shown in Figs. 3 and 9, and detailed description thereof will be omitted. In the method of supplying the fluid to the slag liquid retention portion A, in addition to the above embodiment, for example, the fluid supply means 6 may be provided on the side wall 200 of the tub 2, and from the fluid supply means 6 toward the slag liquid A method of supplying a fluid in the retention portion A; and a method of blowing a fluid into the slag liquid retention portion A by the fluid insufflation means 6 from above the slag liquid retention portion A. The flow system supplied to the slag liquid retention portion A is, for example, air, oxidizing air, oxygen, nitrogen, carbonic acid gas, water vapor, natural gas, city gas, propane gas, coke oven gas, other process gases, etc. One or more of these types are used. The temperature adjustment of the molten slag of the above (a) is usually such that the temperature of the molten slag is lowered by the supply of the fluid. For the flow system, for example, air, nitrogen, water vapor or the like can be used. In relation to the slag upgrading of the above (b), for example, in order to reduce the amount of f-CaO in the slag, oxygen such as air, oxidizing air, oxygen or the like or oxygen gas containing 098108889 32 200951098 may be used. When the gas supply is melted and dissolved, the ruthenium in the smelting is oxidized, which is bonded to f-CaO to form 2Ca0 · Fe2〇3, so the melting point #f CaO is low' when the obtained melted solidified body is used. It can inhibit hydration expansion when the bed material is in the same time. On the other hand, 'when the slag with a large proportion of internal pores is desired', air or nitrogen gas can be supplied to the slag liquid retention portion A, and the operating conditions (for example, the rotational speed of the cooling drum 1 and the cooling drum 4) can be adjusted. And the molten slag s is extruded from the opening 5 in a gas-containing state. Thereby, the supplied gas is sealed in the slag, and a slag solidified body having a large internal pore ratio can be obtained. Because of its high water absorption, such slag is particularly suitable for use in road bed materials and the like. The sensible heat recovery of the molten slag of the above (c) is to recover the fluid supplied as described later and perform heat recovery from the fluid. For the flow system, for example, air, nitrogen, water vapor or the like can be used. Further, by supplying water vapor (water) and a gas containing a hydrocarbon component such as natural gas or coke oven gas to the slag liquid retention portion, a steam reforming reaction occurs, because The sensible heat of the slag is supplied by the endothermic reaction of the reforming reaction, thereby promoting the cooling of the molten slag, and recovering the gas (hydrogen-rich gas) generated by the reaction as a combustible gas or heat recovery. When the hydrocarbon-containing component gas system uses, for example, a decane gas, a reaction of CHAM)-CO+3H2 occurs. Further, the supply of fluid to the slag liquid retention A can also be applied to the embodiment shown in Fig. 3 in which 堰4 is not provided. 098108889 33 200951098 Further, the temperature of the molten slag in the slag liquid retention portion A in the cooling treatment device having the slag liquid retention portion A is adjusted, and (b) the melting is performed in (a) the slag crushing or grinding treatment The powder may be added to the molten slag by increasing the amount of the slag powder produced and (c) the yield of the product. The powder system is like: fused powder. In the case of (coal ash), brick, iron oxide powder, coal dust, sludge, sputum, fly ash, mud iron ore powder, etc., one or more of these may be used. j Use ❹ The temperature of the molten slag in (a) above is adjusted by the addition of the powder to lower the temperature of the smelting melt. By the temperature adjustment by the addition of the powder (in particular, the addition of the powdery slag (slag powder)), "...j 4 has the following effects.藉 By adding the powder granules to the molten slag, for example, by adding 1% to 5 years old, the slag temperature is drastically lowered to promote solidification. In particular, when the product slag having a large melting thickness is rapidly cooled to the inside and a high-quality slag product is to be obtained, the cooling and solidification inside the slag can be effectively promoted. If the amount added exceeds 50%, the slag temperature is excessively lowered and it is easy to agglomerate, so that not only the adjustment of the cooling rate is difficult, but also the adjustment of the shape and thickness is difficult. On the other hand, if the amount of addition is less than 1%, the adjustment of the slag temperature is substantially difficult. Further, when sensible heat recovery is carried out from the solid state slag which has been subjected to the treatment by the cooling treatment apparatus of the present invention, since the amount of slag is increased, the difference between the surface temperature and the internal temperature of the solid solution can be reduced, so that heat recovery can be efficiently performed. . Further, since the cooling and solidification of the molten slag is promoted, the heat load and thermal fatigue of the cold drum 1 or the stretching rolls 3 and the like can be alleviated. 098108889 34 200951098 The above (8) secret-deformation is based on the melting of iron oxide such as sand, fly ash, etc. (10) high oxygen bricks, such as eight 12〇3 source, iron oxide powder or iron powder. The amount of Ca0 in the slag-reducing slag is lowered, and the hydration expansion of the slag solidified body used in the household bed material or the like can be suppressed. Related to the above (e) 'If the addition of the smashing treatment or the pulverization treatment caused by the cooling treatment according to the method of the present invention can be made: • $, the retention of the liquid liquid The addition of the powder of the melt in A can also be applied to the embodiment shown in Fig. 3 which is not provided. In the implementation of this issue, it is particularly good to save energy and reduce emissions (10). It is preferable that the sensible heat recovery of the molten slag is carried out by heat recovery of at least one of the following two types (iXiv) and particularly preferably all. Further (i) heat recovery from the refrigerant passing through the inside of the cooling drum crucible. The crucible (u) is subjected to a heat treatment for melting the dross using a cooling device having a crucible 4 (in the case of a cooling drum 4), and heat recovery is performed from the crucible. 7 Spiral The (4) which is cooled by the cooling drum 1 is further cooled by contact with a refrigerant (e.g., reduced water, air, etc.), and is recovered by recovering the refrigerant. In this method, after the refrigerant is brought into contact with the solvent in the vacant space, the refrigerant exchanged with (4) is recovered. Can take, for example.  (4) A method in which the cooling drum 1 is cooled by cooling means, and a method of transporting the refrigerant to the 098108889 35 200951098 while being in contact with the refrigerant, and then recovering the heat from the refrigerant; (b) cooling by the cooling drum 1 The slag is subjected to various methods such as a method of performing heat recovery from the refrigerant by cooling the container or the cooling device through which the refrigerant is supplied. (iv) in the cooling treatment of the molten slag by using the cooling treatment apparatus having the slag liquid retention portion A, when the fluid is blown into the molten slag in the slag liquid retention portion 4, the blown air The fluid is recovered and heat recovered from the fluid. In the above aspects (1) and (11), heat is recovered from the refrigerant passing through the internal cooling mechanism that cools the drum 丨 or the crucible 4 (preferably, the cooling drum 4x). In the aspect (a) of the above (ill), for example, the conveyance belt 8 of each of the above-described embodiments is covered with a tunnel, and the slag is cooled by circulating a refrigerant inside the tunnel, and the slag is cooled from the refrigerant. Heat recovery. In the form (b) of the above (in), for example, the slag is stored in a cooling container to which the refrigerant is supplied and cooled, and heat is recovered from the refrigerant. For the cooling container, for example, the slag bucket 9 of each of the above-described embodiments can be used, and heat can be recovered from the refrigerant passing through the cooling container. Further, slag may be placed in a cooling device such as a screw feeder or a rotary kiln, and the slag may be cooled by supplying a refrigerant such as air inside, and heat may be recovered from the refrigerant. In the embodiment (IV), 'the cover for fluid recovery or the like is provided above the cooling drum 1, for example, and the fluid having passed through the molten slag S of the slag liquid retention portion A is recovered, and heat recovery is performed from the fluid. . 098108889 36 200951098 Any of the above cases (i) and (iv) are in heat recovery equipment (not shown in Figure 8 for refrigerant or gas heat recovery. The recovered heat can be used as, for example:::: drying heat source, fuel drying Various heat sources such as a heat source of steam. 'In the form (b) of the above (iii), (4) is cooled by a cooling container or a cooling device, and the particle size is the most (four) degree from the efficiency level of sensible heat recovery. In other words, it is preferable to carry out cooling treatment by the embodiment of the first example 1{) to the figure exemplified above. The system shown in Fig. 21 is a schematic front view showing the cooling treatment method of the above (iii)_. In the present embodiment, a cooling treatment device similar to that of the embodiment of Fig. 15 and Fig. 15 is used, and the slag slag Sx or the slag Sx which can be easily separated into a block shape is broadcasted from the device. The slag Sx is further subjected to a crushing treatment by a crushing device 13 such as a crusher, and then inserted into the sealed cooling container 14 by the conveying conveyor 8. The temperature of the slag Sx charged in the cooling capacity 14 is usually 700 to 1000 °C. For the cold chill, the pressurized air as the refrigerant is blown into the container 14, and the slag Sx is cooled. The heated air (hot air) subjected to the sensible heat of the slag Sx is discharged to the outside of the cooling container 14, and is heat-recovered by an appropriate heat exchange means. The melted edge Sx cooled to an appropriate temperature is taken out from the inside of the cooling container 14 and sent to the necessary processing steps. Further, since the rest of the device structure and the cooling processing form are the same as those shown in Figs. 3, 9, 14, and 15, the detailed description is omitted. Fig. 22 is a schematic front elevational view showing another embodiment of the 098108889 37 200951098 in the cooling treatment method of the above aspect (iii). In the case of using the hermetic cooling container 14 shown in Fig. 21, it is necessary to keep the slag and the refrigerant in the container for a certain period of time. When the cold (four) container 14 is only a squat, the processing efficiency is a problem. In the embodiment of FIG. 22, the plurality of cooling containers 14a to 14c are provided, and the cooling containers 14a to 14c (slag charging heat recovery - slag discharge) are sequentially circulated. Then you can perform efficient processing. Further, since the rest of the device configuration and the cooling processing form are the same as those of the embodiment shown in Fig. 21, detailed description is omitted. Fig. 23 is a schematic front view showing another embodiment of the cooling treatment method of the above aspect (iii). In the present embodiment, when slag transfer is performed by the screw feeder 15 which is cooled, the slag is cooled by supplying pressurized air as a refrigerant to the inside. The pressurized air is supplied from the outlet side of the screw feeder 15 toward the inlet side. The air which is circulated in the screw feeder 15 and cools the slag is taken out of the machine and heat-recovered by an appropriate heat exchange means. Further, since the rest of the apparatus configuration and the cooling processing form are the same as those shown in Fig. U, detailed description is omitted.

Further, in the present embodiment, a refrigerant such as mist (water + compressed air) is supplied (sprayed) from the refrigerant supply means 16a to the lower surface of the cooling drum 1, and the drum surface 100 is cooled. In addition to the mist, the refrigerant can be sprayed with water or the like.设备 The equipment on the outlet side of the apparatus, such as the cooling treatment device and the refrigerant supply means 16, 16a, is covered by the lid body 17, and the lid body 17 is connected to the exhaust pipe. A heat exchanger 19 is provided in the exhaust pipe 18. ° In addition, as for the blast furnace slag, it is easy to be amorphized and collapsed due to rapid cooling. After cooling by the drum, the surface layer formed at the contact portion of the drum is the semi-solidified portion of the edge. After the supply of (4) heat = crystal phase disappears, by fog cooling, non-amorphous form is formed (the slag is not cooled as a whole). In the drawings, the anode phase is omitted, and a radiation thermometer is provided. Grasping the temperature of the fuse surface, and adjusting the speed of (10), etc., the chilled swelled Cai cold slag product can be obtained. The recycled product in the cover body 17 is heated by the contact with the molten material to generate heat. The gas (hereinafter referred to as "exhaust gas") passes through the exhaust pipe; 8: = heat is exchanged with the heat medium by the heat exchanger, thereby returning to heat. For example, if the money is used as a heat medium, Exhaust gas _ change = available steam. In the exhaust gas alarm set gas thermometer 20, (4) ^ 098108889 39 200951098 gas gas temperature. In the control device 21, the rear bracket 4 account + straight T system according to the use of the gas thermometer 20 Exhaust gas temperature is measured and becomes the required row The method of the gas temperature is (4) the amount of refrigerant supplied from the refrigerant supply means 16 (for example, the amount of mist or the ratio of gas to water in the case where the refrigerant is misty, and the amount of water in the case of spraying water). Usually, the cooling drum 1 is cooled by circulating cooling water in the refrigerant flow path, but steam may be used as a refrigerant from a part of the cooling water passing through the cooling drum 1 or a part of the cooling water. At least a part of the refrigerant (vapor, water) supplied by the means 16 can thereby make the sensible heat recovery of the slag more efficient. Further, the heat exchanger 19 may not be provided in the exhaust pipe 18, but directly Exhaust gas is used as any one of the heat sources. The melting to the appropriate temperature is checked and Sx' is sent to the necessary processing steps to become the product slag. At this time, slag powder (micronized slag) is generated. The slag powder may be added to the molten slag of the slag liquid retention A as described above to perform temperature adjustment of the molten slag. 22 in the figure refers to the slag powder used for performing such a step. Supply device. 'Because the rest of the device structure and the cooling process are the same as those shown in Fig. 3 and Fig. 4 to Fig. 6, the detailed description is omitted. In the embodiment of Figs. 2A to 24, the cooling device can also be used. In the cooling treatment method of the above (lv), for example, the upper space of the slag liquid retention portion a is covered with a gas recovery cover and the cover is connected to the gas 098108889. 200951098 The discharge pipe will be sent from the Hyun, 杳 _ wheel;:: The two body 'utilize the cover and the gas in the wire as described above, in this embodiment, the component gas is the same as the day (four) or coke oven In addition, it is particularly suitable for the case where the gas is contained in the slag. The point is because the melting, 杳, and 实施4 embodiments are 'at the beginning of operation', ', and 'The liquid retention part is made into: slag s, and the formation of the melting premise needs to supply the melting night staying part A. Therefore, for example, the figure R, 闽n loose implementation form, in the lower, the person, as shown in Figure 8, Figure 9, etc., but the drum 1 and the upper 堰4〇n gentleman & the human barrel 4 χ) interval (open D (Figure Cooling and rolling operation in 9. At this time, when A ^ is in a narrow state or in a closed state, it starts to enter, n-shaped Λ ', and it is easy to generate slag liquid retention A, but also olefin; the cold part is the same as 1 The order is reduced in the formation of the established Hyun, A, y degrees) adjusted to the established A# '# by the above interval (the opening 5 is wide relative to this, (6) can be stabilized to the thickness of the township (10) honey & see Figure 10 to Figure 13 The embodiment is because the method #μ口5 becomes narrow or seals 々..., to make it open, so at the beginning of the operation, a large amount of melting and melting is processed by adjusting the melting and melting of the cold-rolling device. Further & 匕), the slag liquid retention portion 迅速 can be quickly formed. y < The slag liquid retention stagnation liquid level detection hand and the smelting slag receiving capacity η and although the melting degree is controlled At the time of 'changing the number of revolutions of the cooling drum 1 so that the molten residual liquid level is high, a certain thickness of _sx is obtained. The drawing rolls 3 provided in the cooling processing apparatus such as FIG. 4 to FIG. 6 also have an internal cooling mechanism of 098108889 200951098. Fig. 25 is a schematic cross-sectional view showing an internal cooling mechanism according to an embodiment. The stretching rod 3 is provided with a refrigerant inside. The flow path 30' is provided with refrigerant passages 4a and 40b along the axial direction of the roll shafts 31a and 31b. In the present embodiment, only the inside of the stretching roll 3 is formed to be hollow, and the hollow portion is used as a refrigerant. The flow path 30 has a structure in which the refrigerant passages 31a and 31b are connected at both ends of the refrigerant flow path 30. The reason for the structure is as follows. The melt cooling treatment device is not suitable for collecting the sensible heat of the melt through the refrigerant. In one of the slag cooling and heat recovery modes, it is considered that the slag is cooled by the latent heat of vaporization of the cooling water flowing through the refrigerant flow path, and the vapor is recovered from the refrigerant flow path. In the present embodiment, the inside of the roll is hollow to form the refrigerant flow path 30, and the internal cooling water is heated and boiled, and hot water convection occurs, so that the lower portion is in contact with the molten slag. The cooling water 'introduced into the refrigerant passage 30 from the refrigerant passage 31a does not immediately flow out of the refrigerant passage 31b, but is appropriately retained in the refrigerant passage 30 by the above-described hot water convection, and functions as a refrigerant. It is possible to use the latent heat of vaporization to obtain a high cooling effect with less cooling water. In addition, the 'vapor generated in the refrigerant flow path 30 is discharged from the refrigerant flow path 30' and can be easily used in the refrigerant circulation path. The method for producing a slag product according to the present invention is to perform cooling by the cooling treatment method of the present invention, and to perform the crushing treatment and/or the grinding treatment of the solidified slag, if necessary, by using a sieve or the like. Granular, granulated slag products are obtained. The present invention is capable of easily producing a melting cost of 5 mm or more and a melting factor of 5 mm or more. In particular, it is also possible to easily obtain a particle size-degree fuse. There are no restrictions on the types of bribe products. They can usually be used as roadbed materials, coarse aggregates, fine materials, marine soils and other civil materials. (4) Slag products of materials, especially suitable for flat bed materials and coarse aggregates. Since the slag product obtained by the present invention is produced by rapid cooling, the pulverization is suppressed, so that the fine powder portion can be reduced, and when it is used as the marine soil wood #, the sea water is not clouded. Further, since the solidification is rapidly cooled to a layer shape close to the target particle size, the crushing step can be simplified, and coarse aggregates and fine aggregates having less fine particles can be formed. Further, since the dense material is formed, the water absorption rate is low, and it can be used as a hard material for use in asphalt. Further, by performing the solvent modification, the free CaO can be reduced, and it is easy to carry out by aging, and the expansion can be suppressed by atmospheric aging even if the aging of the vapor is not used, and thus it can be used as a road bed material. 〇 (industrial availability) (4) The hair transfer (10) is cooled; the g卩 treatment device and the cooling treatment method are cooled by the roller surface (100) of the single horizontal cooling drum (1). The melting; the inspection is discharged, so that the treatment of the melting after the completion of the treatment, the post-treatment, etc. are easy to 'can also reduce the equipment cost. In particular, when the fused sensible heat recovery is performed, if it is a conventional double-drum type smelting-cooling treatment device, it is desired to perform the cooling treatment in the forward and reverse directions, and the smelting treatment is performed by one heat recovery device. In the process of integrating the opposite direction 2 paths into 1,098108889 43 200951098, the slag temperature is lowered, and efficient heat recovery cannot be performed. In contrast, the present invention is cooled in one direction because the slag is cooled. Exhaust' thus enables efficient heat recovery. Furthermore, 'because of the melt-melting/checking of the horizontal cooling drum through the barrel (2), the falling load of the molten slag is not applied to the horizontal cooling drum (丨), or the falling load can be sufficiently reduced, and thus Even in the case of a large processing apparatus, the molten slag can be processed in a large amount without using a tundish. Further, by selecting the shape of the tub, the molten slag can be expanded toward the width of the drum, and the molten slag can be uniformly cooled on the drum surface. Further, according to the cooling treatment device using the slag liquid retention portion (A) formed by the tub (2) and the drum surface (100), and the cooling treatment method using the molten slag using the device, the dissolution treatment can be effectively promoted. The cooling of the collapse allows the thickness of the slag adhering to the surface of the drum (1〇〇) to be ensured even with the molten slag having a small viscosity, and the solidified slag solidified body can be obtained. Further, according to the cooling treatment device having the stretching roller (3) and the cooling treatment method using the refining and slag using the device, the stretching slag (3) is attached to the molten slag attached to the drum surface (100). The rolling is performed and stretched in the width direction of the drum, so that the molten slag having a high alkalinity and viscosity can be cooled according to high cooling efficiency, and the slag solidified body can be obtained according to high productivity. Further, since the molten slag can be cooled at a high cooling rate, it is possible to obtain a slag solidified body which is not easily pulverized, especially for slag having a high alkalinity. Furthermore, according to the cooling treatment device having 堰(4) and the cooling treatment method of 098108889 44 200951098 using the device, a large liquid retention can be formed by using the crucible (4), the drum surface (10) and the barrel (2). Part (4), and can extend the melting n-band retention time in the π-remaining portion (4) of the refining liquid, so that the cooling (4) can be particularly effectively promoted, and the chilled material (4) (4) port (5) can be extruded. Therefore, 'by increasing the width of the D(5) sufficiently (the degree) can be achieved by cooling the crucible (4) in the direction of rotation from the lower outer peripheral surface toward the anti-refining liquid retention portion (A). The drum (4x) is configured to more effectively promote the melting and melting (four) cooling, and the slab can be more stably obtained. Further, according to the method for producing a slag-containing product of the present invention, a slag product having a desired particle size can be produced at a low cost and stably by using the above-mentioned hydrazine treatment.
