Fused cast AZS block

Description:

Fused cast AZS block is the most important refractory material for ensuring the normal operation of the glass melting furnace. At present, the glass melting furnace in the world increases the melting rate, prolongs the kiln age, and reduces the fuel consumption mainly because of the use of fused cast AZS block. Its performance increases as the ZrO2 content increases.

Advantages:

High refractoriness under load, high strength, good resistance to glass melt erosion, not polluting the glass melt

Application:

Glass melting furnace/kiln, side wall of the melting tank, superstructure, dog-hole corner, throat etc. ...
