Fused Cast AZS Block

  • Fused Cast AZS Block

Product Description And Parameters

Main Composition:ZrO2 + Al2O3

Application:Glass kiln

Capacity:300 tons per month

Size:As your requirements

AZS block is also called fused zirconia corundum brick which contains Al2O3-ZrO2-SiO2. The fused cast AZS block is made of pure alumina powder and zircon sand (consisting of 65% zirconia and 34% SiO2). After the alumina powder and zircon sand are melted in an electric furnace, they are cast into various molds and cooled down to become white solids. Since the content of zirconia is between 33% and 41%, the fused cast AZS blocks are pided into three types: AZS-33#, AZS-36# and AZS-41#.

Features
1.Compact micro-structure.
2.Good erosion resistance.
3.Good thermal shock resistance.
4.High compression resistance.

Application
It is mainly used in glass industry.
