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
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.
