High alumina refractory brick is a kind of neutral refractory with alumina content over 48%. It is formed and calcined from bauxite or other raw materials with high alumina content. Refractories with definite shape and size. According to shape and size, it can be divided into standard brick, ordinary brick, special brick, etc. It has high thermal stability, fire resistance and slag resistance above 1770 C. Used in steel-making electric furnace, glass melting furnace, cement rotary kiln, etc Twenty-foot containers weigh no more than 26 tons. 40-foot containers weigh no more than 30 tons High alumina refractory bricks are used in general industrial furnaces, including iron carbide furnaces, boilers, glass furnaces, blast furnaces, hot blast furnaces, ladles lining and steel casting.
