High Density Fused Casting Zirconia Corundum Brick Refractory For Glass Industry
The fused zirconia corundum brick is a high-performance refractory material designed for extreme thermal and chemical environments. Combining zirconia and alumina, this brick delivers outstanding corrosion resistance, thermal stability, and mechanical strength. The zirconia corundum brick is widely used in glass furnaces, metallurgical units, and high-temperature industrial applications, while zirconia bricks provide durable solutions for demanding refractory linings.
Key Features
Exceptional Corrosion Resistance: The fused zirconia corundum brick resists molten glass, metal slags, and chemical attack, ensuring long-lasting performance.
High Mechanical Strength: Each zirconia corundum brick is dense and wear-resistant, suitable for high-stress areas in industrial furnaces.
Thermal Shock Resistance: Zirconia bricks maintain structural integrity under repeated heating and cooling cycles.
Durable and Long-Lasting: The combination of alumina and zirconia in the fused zirconia corundum brick extends service life under extreme conditions.
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 zirconia corundum brick, zirconia corundum brick, and zirconia bricks offer a unique combination of heat resistance, mechanical strength, and chemical stability, making them ideal 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
