BF Corundum Mullite Brick: High‑Grade Refractory for Blast Furnace Ceramic Cup System

TY Refractory’s premium BF Corundum Mullite Brick is produced from tabular corundum and high‑purity fused corundum. Every BF Corundum Mullite Brick delivers outstanding high‑temperature bending strength, stable refractoriness‑under‑load and tiny permanent linear change for blast furnace ceramic cup and ceramic pad working conditions.

This robust BF Corundum Mullite Brick owns reliable technical indicators: Al₂O₃ content ≥88%, bulk density 3.0‑3.2 g/cm³, apparent porosity ≤13%, cold crushing strength over 150 MPa. Each BF Corundum Mullite Brick keeps stable performance above 1600°C and presents excellent thermal‑shock resistance up to 1100°C. Its dense matrix effectively resists penetration from molten iron, slag and alkali vapors to prolong furnace service campaign.

Besides blast furnace critical hearth zones, the versatile BF Corundum Mullite Brick is also applicable for hot‑blast stoves, steel ladles and torpedo cars. Custom‑sized BF Corundum Mullite Brick can be manufactured per customer drawings for special lining requirements.

Backed by over 20‑year refractory manufacturing experience, our factory holds complete ISO triple‑system certifications and 21 proprietary technical patents. Rigorous batch‑by‑batch lab inspection guarantees consistent quality for every BF Corundum Mullite Brick. Global steel producers select our BF Corundum Mullite Brick to cut maintenance frequency and unplanned downtime.
