【０００２】[0002]
従来、電気炉等の窯炉炉壁の補修は、熱間または冷間で溶損部に耐火物を吹付 けたり、炉停止後の冷間で耐火物を取り替えたりして行なっている Conventionally, repair of kiln furnace walls such as electric furnaces has been carried out by spraying refractory material on the melted part hot or cold, or by replacing refractory material cold after the furnace is stopped.
【０００３】 上記耐火物吹付方式は、窯炉の炉壁残存部に吹付ノズルにより耐火物を吹付け て、溶損部に層状の耐火物層を形成させるものである。In the above refractory material spraying method, a refractory material is sprayed on the remaining portion of the furnace wall of the kiln by a spraying nozzle to form a layered refractory material layer on the melt-damaged portion.
【０００４】 一方、耐火物取替方式は、炉体を冷却後、炉壁残存部を解体除去し、この除去 した部位に耐火れんがや耐火ブロックを積み上げ施工するものである。On the other hand, in the refractory replacement method, after cooling the furnace body, the remaining portion of the furnace wall is dismantled and removed, and a refractory brick or refractory block is piled up on the removed portion.
【０００５】[0005]
しかし、上記した耐火物吹付方式では、溶損面に耐火物吹付材の新たな耐火物 層が形成されるが、その品質は吹付け作業者の技能次第で、品質が一定しなく、 耐久性の面でもばらつきが大きい。さらに、耐火物の吹付時に、材料のリバウン ドロスが２０％〜３０％程度発生するために、材料コストが高くなる。 However, in the above-mentioned refractory spraying method, a new refractory layer of refractory spraying material is formed on the erosion surface, but the quality depends on the skill of the spraying operator, and the quality is not constant, so the durability In terms of Furthermore, when the refractory material is sprayed, rebound loss of the material is about 20% to 30%, which increases the material cost.
【０００６】 また、上記した耐火物取替方式では、炉を冷却し、耐火物を解体して除去し、 耐火物を積み上げ施工して補修するという経過をたどるため、長時間におよぶ補 修時間を必要とする。したがって、炉停止時間が長く、生産量が減少し、さらに 大勢の補修人員を必要とするので、補修コストも高くつくものであった。Further, in the refractory replacement method described above, since the furnace is cooled, the refractory is disassembled and removed, and the refractory is piled up and constructed for repair, a long repair time is required. Need. Therefore, the reactor downtime is long, the production volume is reduced, and a large number of repair personnel are required, resulting in a high repair cost.
【０００７】[0007]
本考案は、上記のような点に鑑みたもので、上記の課題を解決するために、窯 炉の溶損した炉壁を補修するために、金属製コイルを縦横に内装して不定形耐火 物で所定寸法の壁面状の補修用パネル材を形成し、補修する炉壁に並設して炉壁 との間に耐火物補修材を充填施工するために、補修する炉壁に係止して取り付け る炉壁取付金具を上記補修用パネル材の上端部に取り付けたことを特徴とする窯 炉補修用パネル材を提供するにある。 The present invention has been made in view of the above points, and in order to solve the above problems, in order to repair a melted furnace wall of a kiln, metal coils are vertically and horizontally installed to form an irregular fire resistance. Form a wall-shaped repair panel material of a predetermined size with a piece of material, and install it side by side on the furnace wall to be repaired, and lock it on the furnace wall to be repaired in order to fill the refractory repair material with the furnace wall. An object of the present invention is to provide a kiln-furnace repair panel material, characterized in that a furnace wall mounting metal fitting to be attached is attached to the upper end portion of the repair panel material.
【０００８】[0008]
本考案によれば、不定形耐火物の補修用パネル材の上端部に炉壁取付金具を取 り付けて、補修用パネル材を窯炉の補修する炉壁に平行状に取り付けると、補修 用パネル材が中子枠状態に配置することとなり、炉壁と補修用パネル材との間に 耐火物補修材を流し込み充填できて、短時間に補修施工ができる。 According to the present invention, a furnace wall mounting bracket is attached to the upper end of the panel material for repairing irregular refractories, and the repair panel material is mounted in parallel with the furnace wall for repairing the kiln. Since the panel material is arranged in the core frame state, the refractory repair material can be poured and filled between the furnace wall and the repair panel material, and repair work can be performed in a short time.
【０００９】 また、上記補修用パネル材は、金属性コイルを縦横に内装して不定形耐火物で 形成していることによって、補修用パネル材の強度を高められ、炉壁の品質が一 定となって、耐久性よく使用できる。In addition, since the above repair panel material is made of an irregular shaped refractory with metal coils installed vertically and horizontally, the strength of the repair panel material is increased and the quality of the furnace wall is kept constant. It can be used with good durability.
