Refractory high-alumina refractory bricks are a neutral refractory material with an alumina content of more than 48%. High-alumina refractory bricks are formed and calcined from bauxite and other raw materials with high alumina content. Refractory high-alumina bricks have high thermal stability, a refractoriness of over 1770°C, and good slag resistance.
Refractory high alumina bricks are suitable for lining and backing of various industrial furnaces in metallurgy, petrochemical, building materials, ceramics, machinery and other industries. Such as: cracking furnace, reforming furnace, heating device, refining device, regeneration device, hot blast furnace, heating furnace, soaking furnace, heat treatment furnace, resistance furnace, tunnel kiln, roller kiln, shuttle kiln, bell kiln, glass pool kiln etc.
