Alkali Resistance Bricks

Description

Alkali Resistance Bricks Introduce
 
Alkali-resistance brick is a kind of low alumina brick, the Al2O3 content is 30-25%, the main material is low alumina refractory clay, it is a kind of silica-alumina series refractory products with good alkali erosion resistance performance in cement kiln system.
