BF Composite Corundum Brick: High-Performance Lining for Blast Furnace Ceramic Cup

TY Refractory’s BF Composite Corundum Brick is a core refractory lining material specially developed for blast furnace ceramic cups and ceramic pads. This premium BF Composite Corundum Brick is compounded with corundum, silicon carbide and high-performance binders, integrating the strengths of two core raw materials to achieve outstanding comprehensive high-temperature performance.

Every BF Composite Corundum Brick boasts stable core indicators: Al₂O₃ content over 90%, bulk density ranging 3.2–3.4 g/cm³, cold crushing strength above 100 MPa, and refractoriness under load exceeding 1700°C. It passes more than 30 cycles of 1200°C water quenching, delivering extraordinary thermal shock resistance, strong wear resistance and great anti-slag penetration capacity. Its low thermal expansion avoids structural cracking under frequent temperature swings.

Beyond blast furnace hearth and bosh sections, the durable BF Composite Corundum Brick also fits steel ladles, torpedo cars, non-ferrous smelting furnaces and petrochemical reactors. Supported by 38 years of refractory production experience, our factory holds complete three-system certifications and owns an R&D center with 21 patents. Custom sizes and tailored formulas are available for all furnace designs, plus full technical guidance from installation to post-operation maintenance.

Steel mills worldwide choose our BF Composite Corundum Brick to extend furnace campaign life and cut frequent maintenance downtime.
