Product description of alumina silicon carbide brick
Alumina silicon carbide brick is made by special sintering process with super high bauxite, silicon carbide and mullite as main raw materials. The working layer is made of high quality super bauxite and silicon carbide as the main raw materials, and the heat insulation layer is made of low thermal conductivity alumina silicate material through high pressure molding and special sintering process.
Features of alumina silicon carbide brick
Good wear resistance
High density induced
Good high temperature performance
Application of alumina silicon carbide brick
In addition to the application of cement kiln, alumina silicon carbide brick is also suitable for high temperature, wear resistance and thermal shock temperature comprehensive requirements of the kiln, such as particle steel rotary kiln, magnesite incinerator, sintering mullite rotary kiln.
