High Performance Fused Zircon Corundum Brick, Fire Resistant Corundum Refractory Bricks

Description:

Fused Casting Zirconia Corundum (AZS) products were produced by baddeleyite and corundum material,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.

Features:

1). Fine thermal conductivity in the normal temperature.
2).Compact structure
3).Strong resistant erosion stability to the glass liquid.
4).Not color to the glass.

Applications:

Glass industry
