High-alumina brick is a kind of neutral refractory with alumina content above 48%, which is formed and calcined by bauxite or other materials with higher alumina content. The heat stability is high, the New is above 1770 ℃, the slag resistance is good, it is used for lining of steel-making electric furnace, glass furnace, cement converter etc.
High-alumina bricks are mainly used in masonry blast furnaces, hot blast furnaces, furnace top, blast furnaces, reflective furnaces, rotary kiln liner, in addition, the high alumina brick is also widely used as open hearth thermal storage lattice bricks, gating system with plug head, water brick, etc., but high aluminum brick prices than clay bricks, so the use of clay bricks can meet the requirements of the place without using high alumina bricks.
