大の費用と労力を要することになる問題点があった。In other words, a conventional high-temperature metallurgical furnace, for example, a high-temperature metallurgical furnace used in a continuous smelting method for sulfide metal ore, is a smelting furnace in which air and fluid solid fuel are appropriately mixed with raw materials consisting of sulfide metal ore and a solvent. It is a method in which the melt is continuously blown directly into the solution which is a reaction product in the furnace.In general, in Fig. 1, 1 is the smelting furnace, 2 is the melt, 3 is the lance, and 4 is the nose part. , 5 is a rising flue, 6 is a boiler, 6a is an artificial flue of the boiler, and 7 is a joint part.During work, a lance 3 is used to transport raw materials, air, etc. to reaction products in the furnace. Since the liquid is blown directly into the melt 2, a splash is generated, and a part of it rises and scatters into the flue 5, and the joint 7
Alternatively, the boiler artificial flue 6a may be blocked, and as a result, the flow rate of the gas increases due to the reduction in the cross-sectional area of the joint 7 or the boiler artificial flue 6a, causing splash or soot to reach the interior of the boiler and prevent it from adhering to the boiler tube. If the flue is blocked, the suction of gas in the furnace will deteriorate and the amount of raw material or air charged will have to be reduced.In order to dissolve the flue accretion while continuing operation, it is necessary to turn on the burner. There is a problem in that it is necessary to prevent acrision from accumulating in the flue by burning or spraying a solvent, which requires a great deal of cost and labor.
本考案は、その問題点を解決したもので、ノーズ部煉瓦
の部分を下げる簡単な構造にして、スプラッシュの立上
り煙道への飛出しを少なくし好適に実施できるよう提供
するものである。The present invention solves this problem and provides a simple structure in which the nose brick part is lowered to reduce splash rising into the flue and to provide a suitable implementation.
次に、第2図及び第3図に示す本考案の実施例について
説明する。Next, an embodiment of the present invention shown in FIGS. 2 and 3 will be described.
第1図に示す一般的な溶錬炉におけるノーズ部煉瓦4の
部分にスプラッシュ押さえ板10を突設する構造にする
が、詳細には第2図及び第3図に示すように、水冷銅ブ
ロックジャケット8にキャスタブルコーティング9して
スプラッシュ押さえ板10を形威し、該板10の基部を
ノーズ部煉瓦4間に挿入挾持させてノーズ部煉瓦4の表
面より突出するように装設して構成する。In a general smelting furnace shown in FIG. 1, a splash presser plate 10 is provided protruding from the nose brick 4, but in detail, as shown in FIGS. 2 and 3, a water-cooled copper block is used. The jacket 8 is coated with a castable coating 9 to form a splash presser plate 10, and the base of the plate 10 is inserted and held between the nose bricks 4 so as to protrude from the surface of the nose bricks 4. .
なお、スプラッシュ押さえ板10は不定型耐火物であり
、水冷銅ブロックジャケット8内の水冷パイプ8aは炉
外側へ延出して構成する。The splash presser plate 10 is made of a monolithic refractory material, and the water-cooled pipe 8a inside the water-cooled copper block jacket 8 extends to the outside of the furnace.
従って、ノーズ部煉瓦4の部分をスプラッシュ押さえ板
10により下げた状態に形成することができてスプラッ
シュの立上り煙道5への飛び出しが少なくなり、熱伝導
の良い銅を使用することにより突出部の冷却を促進でき
る。Therefore, the nose brick 4 can be formed in a lowered state by the splash holding plate 10, reducing the rise of splash and jumping out into the flue 5. By using copper with good thermal conductivity, the protruding part can be lowered. It can promote cooling.
なお、水冷パイプ8aは炉内側へは入らない構造になっ
ているので、もし炉内突出部が溶損しても水冷パイプ8
aが溶損して水が炉内へ入らないようになっている。Note that the water cooling pipe 8a has a structure that prevents it from entering the inside of the furnace, so even if the protrusion inside the furnace melts, the water cooling pipe 8a
A has been melted down to prevent water from entering the furnace.
このように本考案は、ノーズ部煉瓦間には水冷銅ブロッ
クジャケットにキャスタブルコーティングして形成した
スプラッシュ押さえ板をノーズ部煉瓦表面より突出させ

ことができ、従来の問題点を解決でき、簡単な構造にし
て好適に実施できる特長を有する。In this way, the present invention is constructed by installing a splash control plate formed by castable coating on a water-cooled copper block jacket between the nose bricks so as to protrude from the surface of the nose bricks, which prevents splash or soot from rising up the flue. It has the advantage of being able to effectively suppress and prevent it from flying out towards the body, solving the problems of the prior art, and having a simple structure that can be suitably implemented.
