BF High Alumina Brick: Heavy‑Duty Refractory for Blast Furnace & Hot‑Blast Stove Linings

TY Refractory’s premium BF High Alumina Brick is sintered from high‑grade bauxite raw materials. This metallurgical refractory features low high‑temperature creep, remarkable slag‑erosion resistance and stable thermal‑shock performance, effectively mitigating deformation and spalling risks under long‑term furnace thermal loads.

This industrial brick delivers stable core technical parameters: Al₂O₃ content ≥75%, bulk density ≥2.5 g/cm³, apparent porosity ≤22%, cold crushing strength ≥60 MPa and refractoriness reaching 1790°C. Its dense matrix restricts penetration of molten iron, alkali vapors and corrosive slags, maintaining good dimensional stability under continuous high‑temperature service.

The versatile BF High Alumina Brick fits blast furnace ceramic cup zones, hot‑blast stove checker work, torpedo cars and hot‑metal ladles in steel plants. Custom‑shaped and formula‑adjusted bricks are available per‑customer drawings for special lining configurations.

Backed by over 20‑year refractory manufacturing experience, our factory holds complete ISO triple‑system certifications and 21 proprietary technical patents. Rigorous batch‑wise laboratory testing guarantees consistent product performance. Global steelworks select our BF High Alumina Brick to prolong furnace campaign cycles and cut recurring maintenance costs.
