Fused cast AZS bricks are manufactured by fusing raw material and shaped in the mould. Then after further processes of cooling and burning, the fused cast AZS bricks are final produced.
Fused cast AZS bricks are the most widely used materials in glass industry furnaces. According to its different ZrO2 content， it can be classified as AZS 33, AZS 36, AZS 41, which basically defines their corrosion resistance and their applications.
While according to casting method, they can be classified with regular/normal (PT/RC/NC), oriented (TC/OC/QX), reduced cavity (ZWS/ENC/EC/RC), or without cavity – void free (WS/VF/FC).
