What's Fused Cast 

The term Fused Cast refers to a manufacturing process in which the ceramic bonding is obtained by the solidification of a mixture which has been melted in an electric furnace and cast in liquid state into molds.

Fused Cast AZS Blocks Introduction

AZS fused cast block is also called fused cast block which is abbreviated as AZS because it contains Al2O3-ZrO2-SiO2. Fused cast AZS block is made from pure alumina powder and Zircon sand (composed of 65% zirconia and 34% SiO2). After Alumina powder and zircon sand melting in electric furnace, they are cast into various molds and cool themselves down to become white solid. Because of the different content of Zirconia from 33%-41%, our fused cast AZS blocks can be divided into three types AZS—33#,AZS—36# and AZS—41#.

 

?AZS 36 Blocks Description

Fused cast AZS 36# 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

Different casting methods can produce various shapes and sizes AZS for 
different areas of glass furnaces
