Iron making in blast furnace

Iron making in blast furnace

Oct 10, 2017 Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface area for reactions. Magnetic separation is used to

    Jun 21, 2018 Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent. The carbon is fed to the blast furnace in the form of coke ( pyrolyzed coal) from the coking plant

  • blast furnace | metallurgy | Britannica blast furnace | metallurgy | Britannica

    In Europe, the blast furnace developed gradually over the centuries from small furnaces operated by the Romans, in which charcoal was used for reducing ore to a semisolid mass of iron containing a relatively small amount of carbon and slag. The iron mass was then hammered to remove the slag, yielding wrought iron

    Blast furnace is a reactor to produce iron. Ore reaches molten state and gets separated physically due to density from gangue and impurities. Presence of excess carbon reduces the melting point of iron to 1150oC. Integrated Steel Plants refer to Liquid Iron as Hot metal Pig Iron - allusion to suckling Pigs in Sand molds of a cast floor

    Iron making. The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way. A third group of iron-making techniques classed as smelting
