Description
[14]前記金属酸化物補強材のチップ部分の厚さ(t1)範囲は0.1乃至1mmであり、前記チップ部分の長さの範囲(h)は0.1乃至20mmであり得る。
[15]前記金属酸化物補強材のチップ部分と板状部分が会うコーナー部分の水平断面は曲率半径の範囲が0.1乃至10mmである外弧状であり得る。
[16]前記本発明の目的を達成するためのまた他の解決手段として、第1水冷セクターと第2水冷セクターを準備する水冷セクター準備段階、前記第1水冷セクターと第2水冷セクターの間の空間の外側部に雲母板を挟んで接着する雲母板接着段階、前記第1水冷セクターと第2水冷セクターの間の空間の内側部にT字状の金属酸化物補強材のチップ部分が挿入される補強材挿入段階を含む水冷セクター間の金属酸化物補強材の結合方法により達成される。
[25]図1は、本発明の実施形態による低温溶融炉及び絶縁層構造を示す水平断面図及び拡大断面図である。低温溶融炉10の溶融空間は、多数の水冷セクター100を円周方向に配置して形成される。本発明の水冷セクター100と水冷セクター100の間は、図1に示すように、雲母板200と金属酸化物補強材300を含めて結合される。
[36]前記結合方法において、b)段階とc)段階は作業の容易性及び効率性のために順番を変えて行うこともできる。前記c)段階の以前に無機系接着剤を塗布して接着層を形成し、接着層が固まる前に金属酸化物を締結する段階を含むことができる。
[37]本発明の金属酸化物補強材を含む低温溶融炉は、アーキング現象を防止することができ、水冷セクターの角部分の溶融物による損傷を減らして耐久性が高くなる。また、金属酸化物補強材は、従来の雲母板に比べて交換が容易であり、維持補修にも有用である。
