Product Description

Fire resistant zirconia-corundum brick electrocast heavy duty azs refractory brick azs 33# for glass furnace

Product Description

AZS Series Zirconia Corundum Refractory Brick

Fused cast AZS refractory is also called fused cast brick 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 Bricks can be divided into three types AZS-33#,AZS-36# and AZS-41#.

Description of Fused Cast AZS Refractory Brick

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 of Fused Cast AZS Refractory Brick

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.

Zirconia Corundum Refractory Brick Applications

Bricks are mainly used in the linings in decomposing furnaces for petroleum and chemical industry, as well as the chemical fertilizer industry. They are also used as high temperature kiln linings and furnitures in metallurgical industry.

Zirconia Corundum Brick Manufacturing Process

Made of the zirconite (Industry zirconia ) and industry alumina as the mainly mixed raw material, melting in the electric furnace,casting, annealing, machining, then finished.

Product Application

The Application of AZS Bricks

The most important application of AZS bricks is glass furnace. AZS-33 bricks are mainly used at working tank, fore-hearth, upper structure and crown. AZS-36 bricks have high corrosion resistance and low pollution to glass liquid, they are mainly used at the parts contacting with glass liquid, such as melting tank wall, clarification tank, working tank and so on. AZS-41 bricks have the best glass liquid corrosion resistance and the lowest pollution to glass liquid. Their main application parts are: melting tank wall, throat, kiln weir, charging hole corner brick, bubble bricks, electrode bricks and so on.

Packaging & Shipping

The bricks are packed on wooden pallet with papers in each layer and PP film wrapped outside of the whole pallet.
