Blast furnace
Challenging conditions affect every area of a conventional blast furnace. For the hearth pad and hearth wall, tuyere belt, bosh and belly, lower and upper stack the lining of these areas has to deal with elements such as molten iron, corrosive vapors and abrasion from the solid burden. Raw materials entering through the throat may be a source of wear and tear, while coarse particles and carbon monoxide-rich gases produced as by-products can cause problems from the bottom up.
At Saint-Gobain Performance Ceramics & Refractories, we develop advanced, sustainable solutions for every stage of ironmaking. Our Coranit® Al and SlagR ceramic cup technology reduces CO₂ emissions and extends furnace life. We offer castable and shotcrete options for various furnace repairs, including the hearth and stack areas. With a full portfolio of engineered refractories, we help blast furnace operators reduce the number of repairs, heat losses, fuel rates, costs and meet today’s environmental standards.
