AZS fused cast block

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

AZS fused cast block
  • Bulk density g/cm3: ≥3.75
  • Apparent Porosity %: ≤1.2
  • Cold Crushing Strength Mpa: ≥300
  • Exudation Temperature of Glass Phase: ≥1400
  • Bubble Separation Ratio(1300℃×10h): ≤1.5
  • Anti-corrosion rate of glass liquid 1500℃×36h (mm/24h)%: ≤1.45

TY-AZS series blocks have passed the ISO international certified. High purity raw material, scientific formula, advanced technology and professional guide all contribute to our qualified azs blocks production. Over 10 years producing and marketing experience, we have developed stable customer base overseas and kept long-term cooperation. Need refractories for high temperature furnace fuel?

AZS fused cast block

TY-AZS33 Description
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
