The present invention relates to a water leakage treatment method for a metal water cooling jacket.
It is related with the method performed in the copper smelting method which smelts copper concentrate and a copper raw material especially with a flash furnace.

Generally, the furnace body of a flash smelting furnace used for copper smelting is cooled by a water cooling jacket.
(Japanese Patent Publication No. 03-57169: Patent Document 1)
この場合、水冷ジャケットの水漏れが生じると、炉体への水の浸入による操業への悪影響、炉体レンガ及びキャスターの劣化が問題となる。最悪の場合、炉内の溶湯が炉外へ漏出することになる。 In this case, when water leakage of the water cooling jacket occurs, adverse effects on operation due to water intrusion into the furnace body and deterioration of furnace bricks and casters become problems. In the worst case, the molten metal in the furnace leaks out of the furnace.
ジャケットの修復方法としては、コーキング、肉盛り等があるが、従来技術では操業中に炉体水冷ジャケットを修復することは不可能である。交換のために、長時間にわたる操業停止を余儀なくされる。
又このような水冷ジャケットは、銅の製錬の転炉、精製炉、更には鉄鋼製錬の高炉、転炉、電炉等にも使用され水漏れ対策に苦慮している。

It has been found that water leakage of a water-cooled copper jacket can be stopped.

以下本発明に関して、詳細に説明する。
本発明に関する対象の炉は、加熱炉或いは製錬用の炉である。特に非鉄製錬に於ける自溶炉、ＰＳ転炉、精製炉、連続製銅炉等である。
金属ジャケットは、金属製であり特に熱伝導性の良い銅製が好ましい。又アルミニウム、鋳鉄等も考えられる。
止水液を添加する溶液は、工業用水等である。水漏れを確認後、通常の炉体冷却水とは、別系統とし、止水対策がなされる。
冷却水は、ポンプによる循環利用のため、液温が上昇するが、止水効果を保つための冷却媒体として、氷等を使用し液温上昇を抑制する。
なお、通常の炉体冷却水は、冷却塔を介して循環し、温度コントロールされている。
Hereinafter, the present invention will be described in detail.
The target furnace according to the present invention is a heating furnace or a furnace for smelting. Particularly, a flash smelting furnace, a PS converter, a refining furnace, a continuous copper furnace, etc. in non-ferrous smelting.
The metal jacket is made of metal and is preferably made of copper having particularly good thermal conductivity. Aluminum, cast iron, etc. are also conceivable.
The solution to which the waterstop solution is added is industrial water or the like. After confirming the water leakage, it will be separated from the normal furnace body cooling water and water stoppage will be taken.
The coolant temperature rises because of circulating use by the pump, but ice or the like is used as a cooling medium for maintaining the water stop effect to suppress the rise of the fluid temperature.
In addition, normal furnace body cooling water circulates through a cooling tower, and is temperature-controlled.
止水液は、ラジエータ水漏れ処置に供される市販品等（例えば、輸入販売元：武蔵ホルト株式会社、製造元：ホルト ロイド リミテッド（HOLT LLOYD LTD）製のラドウェルド（RADOWELD）である。）が、使用できる。
止水液の組成は、主にレジン（接着性を有するもの。）、ファイバー（ガラス状のもの）と溶剤である水からなるものである。
更に詳細な組成としては、例えば水84〜85mass%、アレイン酸樹脂6〜8mass%、植物性樹脂2〜3mass%、植物性繊維1〜2mass%、ホウ酸ナトリウム3〜4mass%、リン酸0.2〜0.5mass%、トリエチルアミン0.5〜1mass%、メチルｐ−安息香酸エステル0.05〜0.15mass%、ポリジメチルシリコンエマルジョン0.1〜0.3mass%、染料0.01〜0.03mass%である。
冷却水に対して、0.5〜5.0mass%であることが好ましい。
この程度であれば、水漏れ処置に好適であるからである。
止水液を添加した冷却水は、ジャケット内を循環させるため液温が上昇するが、液温を下げるために氷等を使用し冷却効果を高める。
液温は、40〜80℃の範囲に保持することが好ましい。液温は使用する止水液の止水効果の高い温度範囲で使用する。
The water-stopping liquid is a commercially available product (for example, RADOWELD manufactured by HOLT LLOYD LTD, an import sales company: Musashi Holt Co., Ltd.) that is used for a radiator leak treatment. Can be used.
The composition of the water-stopping solution is mainly composed of a resin (having adhesiveness), a fiber (glass-like), and water as a solvent.
As a more detailed composition, for example, water 84-85 mass%, array acid resin 6-8 mass%, vegetable resin 2-3 mass%, vegetable fiber 1-2 mass%, sodium borate 3-4 mass%, phosphoric acid 0.2- 0.5 mass%, triethylamine 0.5-1 mass%, methyl p-benzoate 0.05-0.15 mass%, polydimethylsilicone emulsion 0.1-0.3 mass%, dye 0.01-0.03 mass%.
It is preferable that it is 0.5-5.0 mass% with respect to cooling water.
This is because this level is suitable for water leakage treatment.
The cooling water to which the still water is added circulates in the jacket, so that the liquid temperature rises, but in order to lower the liquid temperature, ice or the like is used to enhance the cooling effect.
The liquid temperature is preferably maintained in the range of 40 to 80 ° C. Use the liquid temperature in the temperature range where the water-stopping effect of the water-stopping liquid used is high.
冷却水に、止水液を投入すると同時に、金属粉を投入することにより、水漏れが、完全になくなる。
金属粉の添加量は、0.1〜0.5mass%であることが好ましい。
前記金属粉を0.5mass%より多く添加しすぎても、効果が無く好ましくない。また前記金属粉が0.1mass%より少ないと、水漏れ処置効果が低くなるため好ましくない。
By introducing the water-stopping liquid into the cooling water at the same time as the metal powder, water leakage is completely eliminated.
The amount of metal powder added is preferably 0.1 to 0.5 mass%.
Even if the metal powder is added in an amount of more than 0.5 mass%, there is no effect and it is not preferable. On the other hand, when the metal powder is less than 0.1 mass%, the effect of water leakage treatment is reduced, which is not preferable.
また、銅粉であると電解銅粉等容易に、安価に、細かい粉が得られやすいため好ましく、更に銅粉は、延性があり、銅粉同士の密着性も良いからである。また、異種金属同士の電池作用等の相互作用を避けるため、炉体水冷ジャケットと同一素材を使用することが望ましいため、銅製のジャケットに対しては、銅粉を用いる。
また、銅粉は、例えば、粒径が10〜80μｍであることが好ましい。これは水漏れ個所に、密着し、水漏れを処置しやすいからであり、余り大きいと早期に沈降してしまい目的の水漏れ個所に、到達しないことがあるからである。
銅粉には、電解銅粉、アトマイズ粉等があるが、電解銅粉は、孔を塞ぐ為に、針状部分を有するため孔に止まりやすく好ましいと思われる。
Further, it is preferable that the copper powder is an electrolytic copper powder or the like because a fine powder can be easily obtained at a low cost, and the copper powder is ductile and has good adhesion between the copper powders. Moreover, since it is desirable to use the same raw material as a furnace body water cooling jacket in order to avoid interactions, such as a battery effect | action of dissimilar metals, copper powder is used with respect to a copper jacket.
Moreover, it is preferable that a copper powder has a particle size of 10-80 micrometers, for example. This is because it adheres closely to the water leak location and is easy to treat the water leak, and if it is too large, it will settle quickly and may not reach the target water leak location.
The copper powder includes electrolytic copper powder, atomized powder, etc., but the electrolytic copper powder is preferable because it has a needle-like portion so as to close the hole, and is easy to stop in the hole.
以下図１〜図３に則して、具体例を説明する。
止水液、銅粉を含む液体を、水漏れしている自溶炉の水冷ジャケット（図２（３））に循環させる方法として以下の方法を実施してきた。
ドラム缶等の容器に、水、止水液1.5mass%、銅粉0.3 mass%を適量混合させる。止水液は、輸入販売元：武蔵ホルト株式会社、製造元：ホルト ロイド リミテッド（HOLT LLOYD LTD）製のラドウェルド（RADOWELD）を使用した。
A specific example will be described below with reference to FIGS.
The following method has been implemented as a method for circulating a water-stopping liquid and a liquid containing copper powder to a water-cooling jacket (FIG. 2 (3)) of a flash smelting furnace where water is leaking.
A container such as a drum can is mixed with water, water-stopping liquid 1.5 mass%, and copper powder 0.3 mass%. The water stop solution used was RADOWELD manufactured by HOLT LLOYD LTD, an import sales agency: Musashi Holt Co., Ltd.
ジャケットの具体的な一態様は、図１に示すような一体物であって、銅の鋳物に穴を開け、水路としている物が使用されている。
対象の自溶炉は、図３に示すように、ジャケット設置位置（３）が耐火煉瓦の外側に設置される。また自溶炉内の溶体は、１２００から１２５０℃のマットの上部に１２５０から１３００℃のスラグが存在する。スラグの炉内溶体レベル上限を（４）に示す。
ドラム缶内の液体(水＋止水液)を、対象とする水冷ジャケットに循環させる為のルートを作製する。循環にはポンプを使用する。
炉体水冷ジャケットへの冷却水の出入口（図１（１）、（２））を、ドラム缶内の液体を循環させるルートに切り替える。炉体水冷ジャケット内の水を切らさないよう切替えは素早く行うことが重要である。
A specific embodiment of the jacket is an integral body as shown in FIG. 1, in which a copper casting is perforated to form a water channel.
As shown in FIG. 3, the target flash smelting furnace has the jacket installation position (3) installed outside the refractory brick. Moreover, the slag of 1250 to 1300 degreeC exists in the upper part of the mat of 1200 to 1250 degreeC as the solution in a flash smelting furnace. The upper limit of the slag solution level in the furnace is shown in (4).
Create a route to circulate the liquid in the drum (water + still water) to the target water cooling jacket. Use a pump for circulation.
The cooling water inlet / outlet (FIGS. 1 (1) and (2)) to the furnace water cooling jacket is switched to a route for circulating the liquid in the drum. It is important to switch quickly so as not to drain the water in the furnace water cooling jacket.
ポンプにより液体の循環を開始する。
循環中、循環液の温度が上昇するため（ジャケットが高温溶体及び、ガスと接しているため）、氷をドラム缶内に投入し、循環液温度を下げる操作を実施する。液温は、40〜80℃の範囲に保つように氷を投入する。
The pump begins to circulate the liquid.
During the circulation, the temperature of the circulating fluid rises (because the jacket is in contact with the high-temperature solution and gas), so ice is put into the drum can and the circulating fluid temperature is lowered. Ice is added so that the liquid temperature is kept in the range of 40-80 ° C.
氷の添加により、止水液濃度が薄くなるため、氷の溶解に見合った量の止水液及び銅粉を追加する。
上記方法により、操業中に炉体水冷ジャケットの水漏れを停止させること
が可能であった
The addition of ice reduces the concentration of the still water solution, so add an amount of the still water solution and copper powder commensurate with the melting of the ice.
By the above method, it was possible to stop water leakage in the furnace water cooling jacket during operation.

In FIG. 3, the estimated image of the water stop effect which is 1 aspect of this invention is shown.
The first stage shows a state where water is leaking from a pinhole or a crack.
In the second stage, the water-stopping liquid particles adhere to the surface of the base material and bring about a water-stopping effect.
However, if the hole is 0.3mmφ or larger, the water cannot be stopped with only the water stop solution.
In the third stage, the metal powder is collected in the water-stopping liquid particles adhering to the base material, and the pores are narrowed. In the fourth stage, in the gap between the metal powders collected in the water-stopping liquid particles. , Water stop liquid Particles are clogged, water passage is lost, and water stop is performed completely.

The thinnest part on the jacket solution side is 23 mm during fabrication. When PT inspection (liquid penetrant testing) was applied to the jacket during regular repairs,
