Alumina Silicon Carbide Bricks | High Thermal Shock & Abrasion Resistant Refractories for Steel, Foundry, Chemical Plants

Alumina Silicon Carbide Brick | High-Performance Anti-Corrosion Refractory

Alumina Silicon Carbide Bricks are high-performance refractory products made from a combination of premium Al₂O₃ and SiC, offering an ideal balance of abrasion resistance, thermal stability, and chemical durability. These bricks are widely used in high-wear zones of furnaces, such as tapholes, slag lines, and metal-contact zones.

Manufactured using advanced pressing or casting methods and fired at high temperatures, these bricks feature low porosity and high strength, making them suitable for steelmaking, non-ferrous metallurgy, glass, and cement industries.

Key Feature of Alumina Silicon Carbon Bricks:
•Excellent resistance to slag & metal penetration

•Outstanding thermal shock resistance

•High mechanical strength at elevated temperatures

•Low porosity and high density

•Customizable shape, size, and composition

Typical Applications of Alumina Silicon Carbon Bricks:

•🧱Steel ladle working lining and slag line

•🔥Taphole area of blast furnace or BOF

•♻️Glass furnace sidewall & forehearth

•🏗Transition and burning zones of rotary kilns

•⚙️Non-ferrous metal refining furnaces
