Corundum brick is with corundum as main material of refractory products, aluminum oxide content > 90%, corundum brick resorts its good chemical stability, good erosion resistance, good wear resistance, be widely used in petrochemical industry, metallurgical industry, coal gasifier residual oil gasifier, pulp waste liquid gasifier, carbon black reacting furnace and other industrial furnace lining.

The packing density of corundum brick has a relationship to abrasive particle size, particle composition, particle brand, particle size, particle shape and other factors. In general coarse granularity is smaller than fine-grained density, the gap between particles is the smaller, the density is the larger. Hybrid particle packing density is greater than the single particle. The density of particles directly affects the density of corundum brick, The density of the particle is the larger, the density of corundum brick is the larger, the real density of corundum brick refers to the quality of the abrasive contained  in unit volume .

Corundum brick is a kind of important refractory brick, the application is very wide, so what are the properties of high quality corundum brick?

1. Alumina oxide content, common alumina oxide content is the higher, fire resistance is the higher.

2. Corundum brick has high room temperature compressive strength, compression effect is good, directly affects the quality of corundum brick.

3. High temperature resistant effect is good, the starting softening temperature is high.


4. Chemical performance is good, has acid resistance, corrosion resistance, salt resistance and other properties.
