    Another way to create steel from pig iron is the Bessemer process, which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converter.The heat of oxidation raises the temperature and keeps the iron molten. As the air passes through the molten pig iron, impurities unite with the oxygen to form oxides.

    Passage - 1 Materials usually look different from each other. Wood looks very different from iron. Iron appears different from copper or aluminium. At the same time there may be some similarities between iron, copper and aluminium that are not their in wood. An iron smith, look out for freshly cut surfaces of metal rods to see if they have lustre.

    SPONGE IRON PLANT

    Iron ore crushing is not required since sized material has to be purchased. Iron ore of size 5 mm to 20 mm is being used for the production of Sponge iron. Iron ore is being fed to the Ground hopper, from where it conveyed to the Screen with the help of Vibro Feeder, where Oversize i.e. + 20 mm and Undersize i.e. – 5

  • Iron Production

    Iron Production

    Aug 15, 2020 Iron Production. The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron ...

    About 95% of this iron is processed further to make steel, often by the open-hearth process or the Bessemer process, but more recently in the United States and other countries by the basic oxygen process or by an electric arc furnace. The balance is cast in sand molds into blocks called pigs. It is further processed in iron foundries (see casting).
