The silica mullite firebrick produced by our company is made from high-grade bauxite clinker and high-quality silicon carbide as the main raw materials and firing at high temperature.
The silica mullite firebrick produced by our company is made from high-grade bauxite clinker and high-quality silicon carbide as the main raw materials and firing at high temperature. Silica mullite refractory brick has high cold compressive strength and high structural strength in high temperature, good thermal shock resistance, and forms a protective layer during using. Silica mullite firebrick has good wear resistance and good anti-flaking property, and applied for transition zone, cooling zone, kiln mouth of cement kiln and other parts.
Applications of Silica Mullite Brick:
●Transition zone, cooling zone
●Kiln mouth of cement kiln and other parts
Advantages of Silica Mullite Brick:
●high compressive strength
●Good thermal shock resistance

Magnesia mortar for fire bricks is made from high-quality magnesite, magnesia mortar performs well in use with excellent workability, desirable hardening time, high adhesive strength, and good corrosion resistance under high temperature.
Wear-resistant plastic, which is made of special grade alumina, mullite, corundum, siliconcarbide as aggregate and matrix material, mixed by adding binder, additive and plasticizer.
In the high temperature state, the anti-crust refractory castable forms a glaze layer on the surface of the material, preventing the penetration of the glass phase in the cement raw material, thereby playing an anti-skinning effect.
