iron production process

12.5.1.2 Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for

    Ironmaking Process - an overview | ScienceDirect Topics

    Apr 04, 2012 In its Technology Roadmap Research Program, the American Iron and Steel Institute defined an ideal ironmaking process as one that eliminates the need for coal and coke ovens (and hence reduces the emissions of CO 2), that is able to use low-quality iron ores, that requires lower capital investment than the combination of coking oven and BF, and that is able to produce 5000–10,000

    Oct 23, 2017 It has to be derived from iron ore that occurs near the surface when mining. Then the iron derived after a long processing in the blast furnace is handed over to the iron and steel industry to make a huge amount of useful materials. Most of the iron, however, is used in the construction industry

    Iron and Steel Manufacturing

    Iron and Steel Manufacturing Industry Description and Practices Steel is manufactured by the chemical reduction of iron ore, using an integrated steel manufac-turing process or a direct reduction process. In the conventional integrated steel manufacturing process, the iron from the blast furnace is con-verted to steel in a basic oxygen furnace
