Corundum brick


Corundum brick has the advantages of high refractoriness, high strength, high load softening temperature, good high temperature creep resistance, volume stability and strong chemical stability. It has been widely used in oil or gas gasifiers, ethylene engineering gas furnaces, synthetic ammonia plants and other thermal kiln equipment with high temperature, high pressure and serious chemical erosion.
