Description of fused cast AZS refractory
Fused cast AZS block has dense micro structure which ensures its great resistance in glass liquid, thus you don't have to worry about the solidification and other problems. It is widely applied to glass furnace for superstructure, working pool side wall, paving blocks, feeder channels, tank bottoms, C-shaped block and doghouse crown,etc.
Advantages of fused cast AZS refractory
1. Compact microstructure
2. Good erosion resistibility to molten glass
3. Good thermal shock resistibility,high compression resistance
4. Barely rendering blister
5. A variety of formats and shapes for furnace different working areas
Different casting methods can produce various shapes and sizes AZS for different areas of glass furnaces.
Product Applications
Bricks are mainly used in the linings in decomposing furnaces for petroleum and chemical industry, as well as the chemical fertilizer industry. They are also used as high temperature kiln linings and furnitures in metallurgical industry.
Zirconia Corundum Brick Manufacturing Process
Made of the zirconite (Industry zirconia ) and industry alumina as the mainly mixed raw material, melting in the electric furnace,casting, annealing, machining, then finished.

The Application of AZS Bricks
The most important application of AZS bricks is glass furnace. AZS-33 bricks are mainly used at working tank, fore-hearth, upper structure and crown. AZS-36 bricks have high corrosion resistance and low pollution to glass liquid, they are mainly used at the parts contacting with glass liquid, such as melting tank wall, clarification tank, working tank and so on. AZS-41 bricks have the best glass liquid corrosion resistance and the lowest pollution to glass liquid. Their main application parts are: melting tank wall, throat, kiln weir, charging hole corner brick, bubble bricks, electrode bricks and so on.
