• How Do You Turn Iron Into Steel?

     · The oxygen furnace is the most widely used method for making steel. In this method, the intermediate product, pig iron, is combined with steel scrap, usually under 30%, as well as a small amount of flux. Oxygen is blown into the furnace which increases the temperature to over 1700°C. The pressurised oxygen reacts with the high levels of carbon ...

  • Primary Mill Fabriion

    The carbon monoxide gas flows up through the blast furnace, removing oxygen from the iron ore and leaving iron. The iron in the ore reduces to metallic iron from iron because the free energies of CO and CO 2are both lower than that of iron oxide. This greatly increases the temperature and provides the required carbon for steelmaking.

  • What's 'Good Quality' Steel and How Do You Achieve it?

     · There are two basic processes used to produce steel: one involves the use of a basic oxygen furnace (BOF) and the other an electric arc furnace (EAF). Feedstocks used to produce steel in a BOF include molten pig iron and scrap steel. Pig iron is produced from iron ore in a blast furnace and contains approximately 92 to 94 percent iron and 3 to ...

  • Primary Metal Production

    Molten metals tend to dissolve impurities from the ore. For example, many ores that contain native copper have arsenic compounds associated with them. When the ore is melted, the molten copper dissolves the arsenic. As a result, the metal from the furnace can be less pure than the individual metal grains that were originally in the ground.
