Lining Corundum Refractory Brick / Block Thermal Insulation High Bulk Density
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.
The refractory corundum brick is a premium-grade, high-alumina refractory material engineered for industries that demand exceptional thermal resistance and durability. Manufactured with advanced sintering technology, this brick ensures long-lasting stability in high-temperature and chemically aggressive environments.
Key Features
High Thermal Stability: The refractory corundum brick withstands extreme temperatures without deformation or cracking.
Exceptional Purity: The high purity corundum brick is made from carefully selected raw materials to ensure consistent chemical stability and resistance to slag erosion.
Sintered Excellence: Each sintered corundum refractory brick undergoes high-temperature firing to achieve superior density and mechanical strength.
Wear and Corrosion Resistance: The dense structure of the high purity corundum brick resists abrasion and chemical attack, prolonging service life.
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.
The refractory corundum brick, high purity corundum brick, and sintered corundum refractory brick deliver outstanding performance in demanding industrial environments, offering the perfect combination of heat resistance, structural strength, and long-term durability.
