COMPOSITION OF RAW MATERIAL FOR REFRACTORY BRICK AND METHOD FOR PRODUCING REFRACTORY BRICK
To improve both a slaking resistance and hot characteristics of magnesia-spinel refractory bricks in a high temperature range.SOLUTION: A magnesia-spinel refractory brick comprises a composition of: 0.5 to 5 mass% hercynite; 12 to 50 mass% periclase coexisting sintered spinel with a B2O3 content of 0.1 to 0.5 mass%; and 47 to 85 mass% sintered magnesia with the B2O3 content of 0.2 mass% or less. The bricks are obtained by forming the composition and firing at 1450-1650°C.SELECTED DRAWING: None
【課題】マグネシア・スピネル質耐火れんがの耐消化性と高温域における熱間特性を両立して向上させる。【解決手段】ヘルシナイト０．５～５質量％、Ｂ２Ｏ３含有量が０．１～０．５質量％のペリクレース共存型焼結スピネル１２～５０質量％、Ｂ２Ｏ３含有量が０．２質量％以下の焼結マグネシア４７～８５質量％を含む組成物よりなるマグネシア・スピネル質耐火れんがであり、前記組成物を成形し、１４５０～１６５０℃で焼成して得られる。【選択図】なし
