Basic production of iron from ore

Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel

    Mar 20, 2017 Pig Iron. In the electric-furnace production of pig steel from ore, carbon in the product can be kept below 2.2 per cent., and regulated to an extent by the amount of carbon charged, without resulting in excessive loss of iron in the slag or in the production of a pig steel very high in impurities, if a fair grade of ore is used

    Making steel. Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route. Both processes are being continually improved

    Mar 13, 2010 The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the

    At the most basic, steel is made by mixing carbon and iron at very high temperatures (above 2600 F). Primary steelmaking creates steel from a product called “pig iron.”. Pig iron is smelted iron, from ore, which contains more carbon than is correct for steel. The steelmaker uses a system that bubbles oxygen through melting pig iron

    Pig iron is produced by smelting or iron ore in blast furnaces or by smelting ilmenite in electric furnaces . Pig iron is supplied in a variety of ingot sizes and weights, ranging from 3 kg up to more than 50 kg. The vast majority of pig iron is produced and consumed within integrated steel mill complexes.
