BF High Alumina Brick: Cost-Effective Refractory for Ironmaking Furnaces

TY Refractory’s premium BF High Alumina Brick is crafted from premium bauxite as core raw material, serving as standard lining for blast furnaces and hot blast stoves. Every BF High Alumina Brick features low high-temperature creep, outstanding slag erosion resistance and stable thermal shock performance, solving the deformation and spalling troubles plaguing ordinary refractory blocks.

This industrial-grade BF High Alumina Brick owns stable technical indexes: Al₂O₃ content ≥75%, bulk density above 2.5 g/cm³, apparent porosity ≤22%, cold crushing strength over 60 MPa and refractoriness up to 1790°C. Dense compact matrix of each BF High Alumina Brick blocks penetration of molten iron, alkali vapor and furnace slag, maintaining dimensional stability under long-term heavy thermal load.

Besides blast furnace linings, the durable BF High Alumina Brick is widely applied to hot blast stove checker layers, torpedo cars and steel ladles. Custom sizes and tailored formulations of BF High Alumina Brick are available to match diverse furnace structural demands.

Backed by over 20 years of refractory manufacturing, our factory holds complete ISO triple certifications and 21 technical patents. Strict full-batch lab tests guarantee consistent quality of all BF High Alumina Brick products. Global steel plants adopt our BF High Alumina Brick to extend furnace campaign cycles and slash maintenance downtime.
