  • Coal steel World Coal Association

    Iron During the ironmaking process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes (minerals, such as limestone, which are used to collect impurities) Air which is heated to about 1200°C is blown into the furnace through nozzles in the lower section

  • Coal use in iron and steel metallurgy ScienceDirect

    01012013  Iron ore–carbon composites Pressed iron ore–coal mixtures or composites are being studied (particularly intensively in Japan), aiming at shifting the reduction processes in the BF to lower temperatures and so reducing the carbon consumption (Nomura et al, 2007, Ariyama et al, 2010)

    The BOF process uses 25%–35% old steel (scrap) to produce new steel On average, this process uses 1,400 kilograms (or kg) of iron ore, 770 kg of coal, 150 kg of limestone, and 120 kg of

  • 3A3 Direct Iron Ore Smelting Reduction Process (DIOS)

    The Direct Iron Ore Smelting Reduction Process (DIOS) directly uses noncaking coal in a powder or granular form, and iron ore without the use of coke or a sintering process, which are normally required in blast furnace processes The noncaking coal is directly fed to a smelting reduction furnace, while the iron ore is preliminarily reduced

    For this process, coking coal is turned into coke, an almost pure form of carbon, which is used as the main fuel and reductant in a blast furnace Typically, it takes 16 tonnes of iron ore and around 450kg of coke to produce a tonne of pig iron, the raw iron that comes out of a blast furnace

  • Coking Coal for steel production and alternatives Front

    Coal therefore plays three roles in the production of steel: a reducing agent, to turn the pig iron to coke; a source of energy to drive the process by breaking apart molecular bonds; and a source of carbon for the final product (steel is an alloy of carbon and iron) The coal industry loves to point out that wind turbines are made of steel
