- Commodity name： Silicon Mullite Wear-resistant Brick
Description
Introduction
☆ Silica wear-resistant brick ( GUIMO abrasion resistant bricks ) are made of high alumina bauxite, silicon carbide, andalusite as the main raw materials. As one of the materials with high hardness, silicon carbide significantly improves the wear resistance of the product. At high temperature, silicon carbide oxidizes and reacts with high-alumina matrix components to form secondary mullite, which improves the thermal shock stability and corrosion resistance of the product. ability. Andalusite's own micro-expansion and excellent erosion resistance further improve the high temperature volume stability and thermal shock stability of the product.
☆ Compressive strength and load softening temperature are obviously higher than that of anti-stripping high alumina bricks. Its thermal shock stability, corrosion resistance, wear resistance, and thermal conductivity are not high, which are required by the process characteristics of the post transition zone. The life span is 1.5-2 times that of the anti-stripping brick. Good wear resistance is more suitable for cooling belts. The service life can reach more than two years, which is 3-5 times longer than the service life of high alumina bricks. Now, according to the use conditions of different sections of the rotary kiln, different grades of silica bricks with different properties have been applied.
☆ The thermal conductivity of Silica mullite Brick azm 1650 s is lower than that of alkaline products, so the thermal insulation effect of silicon-modified bricks is better. Silica mullite Brick azm 1650 s are used in the secondary firing zone, transition zone, preheating zone, kiln tail, tertiary air duct, calciner, etc. of large rotary kilns. Compared with alkaline bricks, the surface temperature of the cylinder body is lowered by more than 100 ℃.
☆ Silica wear-resistant brick ( GUIMO abrasion resistant bricks ) are currently one of the most widely used shaped refractory products in cement rotary kilns. The product has the characteristics of high temperature resistance, wear resistance, strong corrosion resistance, long service life, high temperature and pressure resistance, effective protection of kiln lining, straight appearance of the product, and convenient construction.
