Description of Corundum Bricks:
Corundum brick has high refractoriness under load, good chemical stability, strong resistance to acidic or alkaline slag, metal and glass liquid, etc., and has a dense structure. Corundum bricks are widely applied in extremely high temperature environment, such as pyrolyzer or reformer in petrochemical industry and chemical fertilizer industry, or all kinds of high temperature furnace lining and kiln furniture in metallurgical industry. The corundum bricks we produce have a high bulk density, fine compressive strength and can serve under high temperature above 1790℃.

High Purity Corundum Brick
High-purity corundum bricks are mainly made of high-purity raw materials and ultra-fine powder through high-pressure forming and high-temperature sintering. They are mainly used in key parts of kilns in steel, petrochemical, non-ferrous, electronics and other industries. They have high temperature resistance, high strength, corrosion resistance and erosion resistance. and other excellent features.
