Corundum Mullite Fire Brick For Steel Smelting Furnace And Various Kiln Lining
Corundum Mullite Fire Brick
Corundum Mullite Fire Brick include fused cast corundum brick, fused alumina corundum brick and sintered corundum brick. 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 refractory corundum brick is fired in the temperature of 1700~1800℃ after drying .Corundum fire brick is good quality high temperature refractory product. Corundum fireproof brick has high refractoriness and good chemical stability. Because corundum firebrick is manufactured with corundum as the principal crystalline phase and contain more than 90% alumina content. Corundum can not only resist acid and alkaline slag erosion, but also the metal and glass liquid strongly.

Features of Corundum Mullite Fire Brick :
Corundum Mullite Fire Brick are high alumina refractory bricks made for extreme demands. The alumina content in Corundum Bricks is from synthetic corundum of high purity, such as white fused alumina or tabular alumina. Additional ingredients are special refractory clays, reactive alumina, and very pure modifications of silica.
