Product Description

Silicon carbide bricks are refractory materials made of SiC as the main raw material. Mohs hardness 9. It is more stable for acidic slag. Contains SiC 72%~99%. It is divided into clay bonded, Si3N4 bonded, Sialon bonded, β-SiC bonded, Si2ON2 bonded and recrystallized silicon carbide bricks.

Product Features

Good wear resistance

Corrosion resistance

High temperature strength

Good thermal shock stability

High thermal conductivity

Small thermal expansion coefficient, etc.

Product Application

It is mainly used as the lining of the lower furnace body of the blast furnace, and its service life is more than doubled compared with the use of traditional refractory materials. In addition, it can be used as the lining of aluminum reduction electrolytic cells and ceramic kiln furniture. It has the advantages of energy saving, extended life, and no pollution to the environment. It can also be used as bricks for blast furnace tuyere water cooling pipes.
