CARBON-CONTAINING CASTABLE REFRACTORY AND METHOD FOR PRODUCING CARBON-CONTAINING CASTABLE REFRACTORY
PROBLEM TO BE SOLVED: To provide a castable refractory that recycles used blast furnace trough slag line materials, containing silicon carbide of 40 mass% or more, where the castable refractory has excellent corrosion resistance, and a method for producing the castable refractory.SOLUTION: A carbon-containing castable refractory recycles used blast furnace trough slag line materials 14, containing silicon carbide of 40 mass% or more. The castable refractory contains: used blast furnace trough slag line materials 14 with a particle size of 2 mm or less of 3-50 mass%; easily-sinterable alumina and/or temporarily sintered alumina with a particle size of 20 μm or less of 3-25 mass%; and spinel containing materials and/or alumina containing materials of 20-80 mass%, as all or part of aggregate, where, the total content of the aggregate is 87-99.5 mass%, provided that the alumina containing materials exclude the easily-sinterable alumina and the temporarily sintered alumina.SELECTED DRAWING: Figure 1
【課題】炭化珪素を４０質量％以上含む使用後の高炉樋スラグライン材を再利用したキャスタブル耐火物であって、耐食性に優れるキャスタブル耐火物、及び、上記キャスタブル耐火物の製造方法の提供。【解決手段】炭化珪素を４０質量％以上含む使用後の高炉樋スラグライン材１４を再利用したカーボン含有キャスタブル耐火物であって、粒径２ｍｍ以下の使用後の高炉樋スラグライン材１４を３〜５０質量％と、粒径２０μｍ以下の易焼結性アルミナ及び／又は仮焼アルミナを３〜２５質量％と、スピネル含有物及び／又はアルミナ含有物を２０〜８０質量％とを、骨材の一部又は全部として含有し、上記骨材の合計量が８７〜９９．５質量％である、カーボン含有キャスタブル耐火物。ただし、上記アルミナ含有物は、上記易焼結性アルミナ及び上記仮焼アルミナ以外のアルミナ含有物である。【選択図】図１
