► 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#.

Corundum Brick is quality high temperature refractory product. It has high refractoriness and good chemical stability. Corundum can resist acid and alkaline slag erosion, and also the metal and glass liquid strongly.

►Advantages

1. Top high-temperature capablility.

2. Excellent thermal stability.

3. Low thermal conductivity

4. Powerful penetrating-proof capability.

5. Good erosion-resistance.

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