Description
本発明は、冶金炉用スラグドアであって、敷居を備えたドアトンネルを有する炉の上殻にスラグドア開口部が設けられており、スラグドアが閉鎖機構によって操作可能であるものに関する。 The present invention relates to a slag door for a metallurgical furnace, in which a slag door opening is provided in an upper shell of a furnace having a door tunnel with a sill, and the slag door can be operated by a closing mechanism.
特許文献1により、3部材で形成されたスラグドアが公知である。 Patent Document 1 discloses a slag door formed of three members.
その際、上側ドア部分またはドア扉は水平軸の周りを旋回可能なゲートによって形成され、ゲートの下方には2つの、垂直軸の周りを旋回可能な指状ドア扉が設けられている。 In this case, the upper door portion or door is formed by a gate that can pivot around a horizontal axis, and two finger-like doors that can pivot around a vertical axis are provided below the gate.
ゲート用旋回機構も、下側ドア扉用調整機構または閉鎖機構も、炉殻の炉壁に配置されている。 Both the gate turning mechanism and the lower door door adjusting mechanism or closing mechanism are located on the furnace wall of the furnace shell.
本発明の課題は、構造支出が少なく、特に既存の冶金炉においてさしたる改造措置なしに追加設置も可能とするスラグドアを明示することである。 It is an object of the present invention to specify a slag door that requires little structural expenditure and that can be additionally installed without modification, particularly in existing metallurgical furnaces.
この課題は、本発明によれば、冶金炉用スラグドアであって、敷居を備えたドアトンネルを有する炉の上殻にスラグドア開口部が設けられており、スラグドアが閉鎖機構によって操作可能であるものによって解決される。 This subject is a slag door for a metallurgical furnace according to the present invention, in which a slag door opening is provided in the upper shell of a furnace having a door tunnel with a sill, and the slag door can be operated by a closing mechanism Solved by.
その際、閉鎖機構は落下する屑鉄から保護するために炉壁の外側で炉壁に前置して配置されており、スラグドア開口部の内法断面は少なくとも2つの水平旋回可能なドア扉によって閉鎖可能であり、ドア扉は少なくとも3つの位置で鎖錠可能であり、これらの位置に付属する第1位置ではドア扉が実質的に1平面で直立しており、第2位置は共通平面に垂直であり、かつ開放位置を意味しており、第3位置ではドア扉が、炉内部の方向を向く鋭角を成し、この鋭角がドア扉の間で開口隙間を解放する。 In that case, the closing mechanism is placed in front of the furnace wall outside the furnace wall to protect it from falling scrap iron, and the internal section of the slag door opening is closed by at least two horizontally pivotable doors Yes, the door door can be locked in at least three positions, and in the first position attached to these positions, the door door is substantially upright in one plane and the second position is perpendicular to the common plane. In the third position, the door door forms an acute angle facing the inside of the furnace, and this acute angle releases the opening gap between the door doors.
好ましい諸構成は従属請求項から明らかとなり、それらの本質は4つのドア扉が対で上下に配置して設けられており、ドア扉が相互に独自に操作可能であることにある。 Preferred configurations will become apparent from the dependent claims, the essence of which is that four door doors are provided in pairs and arranged vertically and the door doors can be operated independently of each other.
好ましくは、外部に向かって鋭角で開放されることになる位置でもドア扉はなお鎖錠可能であり、ドア扉縁部の間に形成される隙間を通して、管理下にスラグ排出が可能である。 Preferably, the door can still be locked even at a position where it will be opened at an acute angle towards the outside, and the slag can be discharged under control through a gap formed between the door door edges.
以下、図面を参考に本発明を説明する。 The present invention will be described below with reference to the drawings.
これらの略図において冶金炉の壁は示唆してあるだけであり、符号1としてある。 In these diagrams, the wall of the metallurgical furnace is only suggested and is denoted by 1.
この壁にドア開口部2が設けられている。このドア開口部2の前に、しかもより正確に述べるなら炉壁によって形成される壁面の前に、つまりこの壁面に前置して、枠3が象徴的に示唆してあり、この枠にドア扉4、5、6〜9が固着されており、またはこの枠によって保持される。 A door opening 2 is provided on this wall. In front of the door opening 2 and more precisely, in front of the wall formed by the furnace wall, that is, in front of the wall, a frame 3 is symbolically suggested, and this frame has a door Doors 4, 5, 6-9 are fixed or held by this frame.
ここに図示しない閉鎖機構が各ドア扉について枠3と結合されている。 A closing mechanism (not shown) is connected to the frame 3 for each door.
これらの図面の個々の図は、ドア扉がいかなる位置を占め得るかを示している。 The individual figures in these drawings show what position the door door can occupy.
図1もしくは図2に、しかも上側の図には、閉鎖状態が示してある。 The closed state is shown in FIG. 1 or FIG.
炉内部に接近する必要性に応じて、一方または両方のドア扉を開放することができる。 Depending on the need to access the furnace interior, one or both doors can be opened.
その場合特殊性はそれぞれ図1もしくは図2の下側図に示してあり、しかもここではドア扉が‐炉内部の方向を向く‐鋭角を成し、この鋭角により、対向するドア扉縁部の間に隙間が残ることになる。ドア扉のこの運動性は、スラグを押し戻すことによって敷居の清浄を可能とする。 In that case, the specialities are shown in the lower part of FIG. 1 or 2 respectively, and here the door doors-facing the inside of the furnace-make an acute angle, which makes the edge of the opposite door door edge A gap will remain between them. This mobility of the door door allows the sill to be cleaned by pushing back the slag.
最後になお、外向きに開放された鋭角におけるドア扉の位置は図面に示していない。その際、内向き位置におけると同様に、対向するドア扉縁部の間で隙間が解放され、この隙間は管理下にスラグ流出を可能とする。 Finally, the position of the door door at an acute angle opened outward is not shown in the drawing. At that time, as in the inward position, a gap is released between the opposite door door edges, and this gap allows slag outflow under control.
自明のことであるが、ドア扉の位置は任意の別の位置でも鎖錠可能であるが、しかし少なくとも前記諸位置が重要である。 Obviously, the door door can be locked in any other position, but at least the positions are important.
例えばドア扉が個々に調整可能かつさまざまな位置で鎖錠可能である場合、これは、炉からのスラグ流出量および/または炉内のスラグ高さを制御可能とする可能性を生じる。 For example, if the door door is individually adjustable and lockable at various positions, this creates the possibility of allowing control of the slag outflow from the furnace and / or the slag height in the furnace.
最後に図3は、この場合4つの対で配置されるドア扉の異なる位置をやはり示す。 Finally, FIG. 3 again shows the different positions of the door doors, which in this case are arranged in four pairs.
開放位置のとき下側ドア扉はスラグ管理と敷居の清浄とに役立つ一方、上側ドア扉はその開放位置のとき、例えば整備作業を実施できるようにするために炉内部へのさらなる接近を可能とする。 When in the open position, the lower door door helps to manage slag and clean the sill, while the upper door door allows further access to the furnace interior when in the open position, for example, to allow maintenance work to be performed. To do.
