Corundum and Corundum-mullite Bricks Series
Description
Corundum bricks are a kind of aluminum-silicon refractory product with corundum as the main crystal phase. By adding some other chemical mineral components, it can form composite products, such as zirconium corundum bricks, chrome corundum bricks, titanium corundum bricks, etc.
Features
Corundum bricks have the characteristics of high melting point, good slag resistance, high strength and hardness, and abrasion resistance.
Corundum mullite bricks have good high temperature strength, high temperature creep resistance, thermal shock resistance and erosion resistance.
Application
Corundum bricks are often used in metallurgy, chemical industry, glass, ceramics and other industrial kiln lining.
Corundum mullite bricks are mainly used in glass furnace superstructure , feed channel brick, cover plate, molding parts, middle temperature carbon black reactor lining and other thermal equipment lining.
