High Alumina Brick: Versatile Sintered Refractory for Metallurgical & Ferroalloy Ladle Linings

TY Refractory’s premium High Alumina Brick is sintered from carefully‑selected bauxite raw materials. This multi‑grade refractory features low high‑temperature creep, remarkable slag‑erosion resistance and stable thermal‑shock performance, coping with cyclic thermal load and chemical corrosion inside various high‑temperature industrial furnaces.

This robust brick covers flexible technical grades: Al₂O₃ content ranging 45‑90%, bulk density 2.3‑3.0 g/cm³, apparent porosity ≤20%, cold crushing strength ≥50 MPa and refractoriness reaching 1790°C. It can withstand more than 25 thermal‑shock cycles. Dense brick matrix restricts penetration of molten metal and corrosive slag, maintaining stable structural performance under long‑term high‑temperature service.

The versatile High Alumina Brick finds wide applications for ferroalloy ladles, blast furnaces, hot‑blast stoves, steel ladles and general‑purpose industrial kilns. Custom‑sized bricks with adjusted alumina grades 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 metallurgical plants select our High Alumina Brick to extend furnace service cycles and cut recurring maintenance costs.
