Fused Corundum Refractory Brick includes two types of Sintered Corundum Brick and Fused Cast Corundum Brick. Sintered Corundum Brick adopts sintered alumina as the raw material through the sintering process. Fused Cast AZS Brick can be made of fused alumina as the raw refractory material through the process method of sintering And also can use phosphoric acid or other adhesive to make Unburnt Corundum Fire Brick.
Refractory Fused Corundum Bricks 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 the 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 fire clay and binding agent through molding by fire brick machine after mulling. The density of fire brick is about 2.75~2.85g/cm3. After drying the refractory bricks are fired at a temperature of 1700~1800℃.
