Description:
Fused zirconia corundum AZS bricks are mainly used in glass industrial tank kilns, which have the characteristics of high resistance to molten glass and low pollution to molten glass. 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 bricks:
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.

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 fused zirconia corundum 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.
Packaging of fused zirconia corundum AZS bricks:
Packed by sea-worthy wooden pallet + shrink wrapped + carton For example, Standard size of Fireclay brick : 230x114x65mm Shipping : 384pcs/plt x 18plts in one 20 feet container;
