Corundum brick is made of corundum as the main raw material. It contains more than 90% Al2O3. Due to its good stability, good corrosion resistance and excellent wear resistance, it is widely used in the petrochemical industry, metallurgical industry and the lining of coal gasifier, residual oil gasifier, pulp waste gasifier, the carbon black reactor and other industrial furnaces.
The bulk density is related to the particle size, particle distribution and particle shape. Generally, magnesia carbon brick with coarse particles have lower bulk density than those with fine particles. The smaller the gap between the particles, the greater the bulk density of the bricks. Bricks with mixed particles have higher bulk density than those with single particles. The bulk density of corundum brick increases with the density of particles.
Corundum brick has high cold compressive strength , which will directly affect the quality of the bricks. It has high Al2O3 content. The higher the Al2O3 content, the better the refractories performance of the bricks. It has high softening temperature and good high temperature performance. It has good chemical properties and excellent resistance to acid and alkali. It has good thermal shock resistance and high strength.It has wide applications.
