High Alumina Corundum Refractory Bricks High Temperature Kiln Linings
The corundum refractory bricks are premium high-alumina ceramic materials designed for extreme-temperature applications. Each corundum brick provides exceptional wear resistance, thermal stability, and chemical durability, making it ideal for furnaces, kilns, and other high-temperature industrial equipment.
Key Features:
Superior Thermal Resistance: The corundum refractory bricks withstand high temperatures with minimal thermal expansion, ensuring stable performance under prolonged heat exposure.
Excellent Mechanical Strength: Each corundum brick offers high compressive and abrasion resistance, suitable for demanding industrial conditions.
Chemical Stability: Resistant to slag and acidic or alkaline environments, the corundum refractory bricks maintain structural integrity over extended periods.
Precision Manufacturing: Produced with exact dimensional control, each corundum brick fits seamlessly into furnace linings for efficient installation.
Description:
The sintered corundum products were produced by sintering of high purity fused corundum, synthetic mullite and chromium oxide. They have high bulk density, high compressive strength, good thermal shocking resistance, and good corrosion resistances to acids and alkali. They are not influenced by H2, CO gases at use.
Features:
1. high bulk density
2. high compressive strength
3. good thermal shocking resistance
Applications:
Widely used as linings in decomposing furnaces for petroleum and chemical industry,
as well as chemical fertilizer industry. They also used as high temperature kiln linings
and furniture’s in metallurgical industry.
