Low Creep Clay Bricks
- Description
-
The low creep high alumina brick used in hot blast furnace is mainly made of high quality bauxite, white corundum, mullite and "three stones". Combined with compound ultrafine powder and admixture. It is formed by high pressure forming and sintering at high temperature. It is mainly used for the upper masonry of the air furnace. It has the characteristics of high temperature resistance, high compressive strength, high load softening starting temperature, high temperature volume stability and excellent creep performance.
