High Temperature Fused Cast Mullite Brick Ceramic Fire Bricks Refractory

Quick Detail:

1, Low permanent linear change on reheating
2, Good Thermal Shock Stability
3, High dense structure

Description:

Mullite brick IS characterized by good high temperature resistance and good thermal shock resistance, whick comes into being mullite through calcine with clay, high alumina materials and ceramics.

Applications:

1, Sulfuric cracking furnace
2, Fibrous glass furnance
