AZS,33,36, 41#.

It produced by casting process after batch fused. The casting refractories mainly include fused AZS blocks, fused α-Al2O3 blocks, fused β-Al2O3 blocks, fused α-β alumina. Comparing with bonded refractories, fused casting blocks formed with bigger size grain, more compact, less porosity and high strength under normal and high temperature. Moreover fused casting blocks have exclusive resistance on glass corrosion and scour, it popularly used at glass melting tank and super-structure of furnaces.
