Product Description

Factory supply zirconia corundum brick high quality AZS 33# 36# 41# fused cast refractory brick for glass kiln

Product Description

Fused Zirconia Corundum Brick Introduction

AZS 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.

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

Fused Zirconia Corundum Brick Application 

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.
