Fire Resistant Corundum Refractory Bricks , Fused Zircon Corundum Brick
The fused zircon corundum brick is a high-grade refractory material designed for extreme service conditions. Produced through an electrofusion process at ultra-high temperatures, it combines zirconia and alumina to achieve outstanding resistance to chemical corrosion, high-temperature strength, and wear resistance.
Key Features:
Excellent Corrosion Resistance: The fused zircon corundum brick offers superior protection against molten glass, metal slags, and alkali vapors.
High Density and Strength: Each electrocast zirconium corundum brick is produced by advanced casting technology to achieve a dense structure with minimal porosity.
Outstanding Thermal Shock Resistance: Maintains structural integrity under frequent temperature fluctuations.
Long Service Life: Both fused zircon corundum brick and electrocast zirconium corundum brick provide extended operational performance in severe industrial environments.
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.
The fused zircon corundum brick and electrocast zirconium corundum brick deliver exceptional thermal stability, corrosion resistance, and wear performance, making them the preferred choice for the most demanding refractory applications.
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
