Product Description Product DescriptionCorundum Brick of refractory product with corundum Corundum BrickCorundum Brick is a kind of refractory product with corundum as the main crystal phase and contains over 90% aluminium oxide content. Corundum fire bricks have very high cold crushing strength that can reach up to 340MPa and high apparent initial softening temperature that is over 1700oC. Corundum refractory brick can be used in blast furnace, hot blast stove, glass furnace and etc. Corundum Brick SalesCorundum Brick sales is quality high temperature refractory product. It has high refractoriness and good chemical stability. Because it is manufactured with corundum as the principal crystalline phase and contain more than 90% alumina content. Corundum can resist acid and alkaline slag erosion, and also the metal and glass liquid strongly.

Fused Cast Corundum Brick is manufactured with commercial alumina and little sodium carbonate and quartz powder fusing in the quartz powder and through process of casting and annealing, and then form the shape and size through machining.Fused Alumina Corundum Brick is made of fused alumina particle and fines adding little fireclay and binding agent through molding by brick machine after mulling. The density of green brick is about 2.75~2.85g/cm3. After drying the bricks are fired in the temperature of 1700~1800oC.
