Fused Cast AZS 33# Block

Fused cast AZS 33# 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
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
