Silica Mullite Refractory Brick
Silica mullite refractory brick are made of high-quality super bauxite and silicon carbide as the main raw materials.
Description
1.Features and Functions of silica mullite refractory brick
silica mullite refractory brick has strong wear resistance, high corrosion resistance, strong anti-stripping performance, it is not suitable to hang kiln skin at high temperature, and the thermal insulation layer has the characteristics of low thermal conductivity.
silica mullite refractory brick can achieve the dual functions of lowering the temperature of the carcass, saving energy and reducing consumption, and can greatly extend the life of the rotary kiln. It is an ideal lining material for the cooling zone and transition zone of the new dry-process cement kiln.
