High Density Fused Casting Zirconia Corundum Brick Refractory For Glass Industry
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
