Product Description

Kiln Melting Refractory Zircon Corundum Block Fused Cast Azs Brick for Glass Furnace 

Product Description

Fused Cast Azs Refractory Bricks also known as fused zirconia corundum bricks, are made by carefully selected zircon sand and industrial aluminum oxide powder in a 1:1 ratio, with a small amount of flux added, mixed evenly, melted at 1800~1900 ºC, and then cast into shape. Generally, zirconium corundum bricks can be divided into several grades according to the content of ZrO2, such as three grades of 33%, 36% and 41%. They have high melting point, good chemical stability, and strong corrosion resistance to acid and alkaline media, especially molten glass.

Features of AZS Brick

1.Casted by melting raw material in the mold, then cooling and solidification.
2.Strong glass corrosion resistance and high thermal shock stability.
3.Good wear-resistance,slag-resistance and alkali corrosion resistance.
4.High-purity raw material, barely no pollution.
5.Top quality, long service time.
 

Shapes and sizes: there are great variety of formats and shapes which are available for different forming and special machine processes.
