  • Blast furnace metallurgy Britannica

    2021-7-21 · In Europe, the blast furnace developed gradually over the centuries from small furnaces operated by the Romans, in which charcoal was used for reducing ore to a semisolid mass of iron containing a relatively small amount of carbon and slag. The iron mass was then hammered to remove the slag, yielding wrought iron.Recycling of Blast Furnace Sludge to the Blast Furnace via,Ore-based steelmaking generates various residues including dusts, sludges, scales and slags. Recycling of these residues within the process or via other applications is essential for sustainable production of steel. In blast furnace (BF) ironmaking, the gas-cleaning equipment generally recovers the particles in the off-gas as dust and sludge.
