METHOD OF PRODUCING ALUMINA SILICA BRICK CONTAINING CORDIERITE
PROBLEM TO BE SOLVED: To provide a method of producing an alumina silica brick containing cordierite having improved creep resistance and sufficient thermal shock resistance as well.SOLUTION: The method comprises: mixing a refractory raw material compound with an addition of a binder, molding and burning at 1100°C or higher and 1400°C or lower. The refractory raw material compound contains: 60 mass% or more and 88 mass% or less of andalusite and/or sillimanite having a particle size of smaller than 3 mm; 10 mass% or more and 30 mass% or less of cordierite having a particle size of 0.074 mm or larger and smaller than 3 mm; 2 mass% or more and 12 mass% or less of clay; and cordierite having a particle size of smaller than 0.074 mm can be included therein in an amount of at most 5 mass% (including 0).SELECTED DRAWING: None
【課題】耐クリープ性を向上ししかも十分な耐熱衝撃性を有するコージェライト含有アルミナ−シリカれんがの製造方法を提供する。【解決手段】粒度が３ｍｍ未満のアンダリュサイト及び／又はシリマナイトを６０質量％以上８８質量％以下、粒度が０．０７４ｍｍ以上３ｍｍ未満のコージェライトを１０質量％以上３０質量％以下、及び粘土を２質量％以上１２質量％以下含有し、粒度が０．０７４ｍｍ未満のコージェライトの含有量が５質量％以下（０を含む。）である耐火原料配合物に、バインダーを添加して混練し、成形後、１１００℃以上１４００℃以下で焼成する。【選択図】なし
