An Overview of Steelmaking Process Steel Technology
The first metallurgical step involved in this process is to reduce iron ore to metallic iron in a blast furnace, using coke as both a fuel and reducing agent The produced metallic iron contains a relatively high proportion of carbon (4%) and it is passed to the steelmaking process in the form of liquid at approximately 1450 C, called as 'hot 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 051 in chunks, which increases surface Ironmaking 101 – From Ore to Iron with Blast Furnaces 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 Iron Ore Smelting Process Bright Hub Engineering

The blast furnace process Download Scientific
Iron blast furnace is used in the metallurgical field to extract molten pig iron from its ore through a reduction mechanism The furnace is a vertical shaft with circular cross section A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom All the three ingredients are Extraction of Iron Metallurgy Blast Furnace Why does the blast furnace emit so much CO 2? Roughly 80–90% of CO 2 emissions from iron and steel production is generated by the blast furnace process This owes to the two functions of the blast furnace (1) Reduction of iron ore In this demonstration plant, verification of hydrogen Carbon contained in coke is used to remove oxygen from KOBELCO Group’s Value Creation KOBELCO Group
