BF Compound Corundum Bricks Applications: From Blast Furnace Hearth to Bosh

Proper refractories for critical blast furnace linings ensure stable production and avoid costly unplanned shutdowns. BF Compound Corundum Bricks become the top selection for blast furnace working zones. Optimized BF Compound Corundum Bricks integrate outstanding thermal shock resistance and superior slag corrosion resistance for long service life. Manufactured with high-purity corundum and composite mineral additives, premium BF Compound Corundum Bricks alleviate continuous furnace erosion, extend lining cycles and cut maintenance costs.
Blast furnace linings operate under severe conditions above 1450 °C, enduring constant erosion from molten iron and alkaline slag, which quickly damages ordinary refractories. With unique solid-solution microstructure, wear-resistant BF Compound Corundum Bricks maintain dimensional stability under frequent thermal cycling. Dense-grade BF Compound Corundum Bricks feature bulk density above 3.10 g/cm³ and apparent porosity below 16%, effectively preventing penetration of hot metal and molten slag.
Corrosion-proof BF Compound Corundum Bricks form compact protective layers against slag infiltration. These BF Compound Corundum Bricks deliver cold crushing strength over 95 MPa and refractoriness under load exceeding 1680℃. Practical operation shows blast furnaces lined with BF Compound Corundum Bricks achieve longer campaign life, reduce downtime and lower overall operating expenses for iron manufacturers.
