Fused Zirconia Corundum Refractories For Glass Industry Zirconium Corundum Brick
Fused zirconia corundum AZS series
Fused zirconia corundum AZS series products mainly use industrial alumina, zirconia, zirconium silicate as raw materials, through the arc furnace melting, crystallization, casting, insulation, processing, production of refractory products. This product is a key material of glass and glass products kiln, according to casting, can be divided into ordinary (PT), (QX), quasi tilt shrinkage (ZWS), no shrinkage (WS), according to the chemical composition of products, can be divided into:
Oxidation casting AZS-33,Oxidation casting AZS-36,Oxidation casting AZS-41
