High alumina refractory brick is a kind of neutral refractory material. It is formed and calcined by bauxite or other raw materials with high alumina content. It has high thermal stability. The refractoriness of high alumina refractory brick is higher than that of clay brick and semi-silica brick, reaching 1750~1790℃, and it belongs to advanced refractory material. High alumina refractory brick contains more Al2O3, which is close to neutral refractory material. It can resist the erosion of acidic slag and alkaline slag. Because it contains SiO2, its ability to resist alkaline slag is weaker than that to resist acidic slag.
High alumina refractory brick is mainly used for masonry of blast furnace, hot blast furnace, electric furnace roof, blast furnace, reverberatory furnace, rotary kiln lining. In addition, high alumina brick is also widely used as flat furnace regenerative checker brick, plug for pouring system, nozzle brick, etc.
