AZS Bricks Introduce


AZS Brick is a kind of fused cast zirconia-corundum refractory brick which is short writing of abbreviation that AZS from “A” of Al2O3, “Z” of ZrO2 and “S” of SiO2. Such as No. 33 fused cast zirconia-corundum refractory brick adopts the “AZS-33#” as its abbreviation, No. 36 fused cast zirconia-corundum refractory brick adopts the “AZS-36#” as its abbreviation and No. 41 fused cast zirconia-corundum refractory brick adopts the “AZS-41#” as its abbreviation.

 

Application of AZS Bricks


The AZS bricks are mainly applied for the top and bottom structure of melting chamber. Such as melting tank, the tank wall brick, the paving brick, the forehearths and so on. The high corrosion part shall be AZS 41#, such as the feeding part, the throat, the bubble brick, the furnace weir, the burner block, the tongue brick the discharging part and so on.
