SiC-mullite brick
Description:
SiC-mullite brick is currently one of the most commonly used refractory products in cement rotary kiln. This product has the characteristics of good abrasion resistance, high temperature structure strength, strong anti-stripping property, good thermal shock stability, and can continuously form a protective film during use. It uses high-quality high-alumina bauxite, silicon carbide, and andalusite as its main raw materials.
Advantage:
Good abrasion resistance, high temperature strength, strong anti-stripping property, good thermal shock stability
Application:
Rotary kiln transition zone decomposition zone
