BF Compound Corundum Bricks: Composite Refractory for Blast Furnace Ceramic‑Cup & Ceramic‑Pad

TY Refractory’s premium BF Compound Corundum Bricks are compound‑sintered from high‑purity corundum, silicon carbide and specialized binders. This composite refractory delivers balanced high‑temperature stability, reliable thermal‑shock resistance and outstanding wear‑proof performance for the severe working zones of blast furnace hearth ceramic cup and ceramic pad.

This robust brick features stable core technical indexes: bulk density 3.0‑3.5 g/cm³, apparent porosity ≤16%, cold crushing strength ≥80 MPa and refractoriness reaching above 1790°C. Its dense compact matrix effectively resists penetration of molten iron, slag and alkali vapors. Precise dimensional accuracy guarantees tight assembly joints during on‑site masonry, eliminating gaps and medium infiltration.

Apart from blast furnace ceramic cup systems, the versatile BF Compound Corundum Bricks are also applicable for hot‑blast stoves, torpedo cars and hot‑metal ladles. Custom‑shaped bricks can be strictly manufactured according to customer furnace drawings for special lining geometries.

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 in‑house inspection guarantees consistent quality. Global steel plants adopt our bricks to extend blast‑furnace campaign cycles and cut frequent maintenance downtime.
