Process of Steel-making from Iron Ore. Steel is an alloy consisting mainly of iron, carbon and other elements. According to its carbon content, iron can be divided into pig iron and wrought iron. Pig iron contains between 2.11 and 4.5 percent carbon, wrought iron less than 0.0218 percent and steel between (0.0218 and 2.11 percent)

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

Apr 10, 2020 Iron products evolved during this time, beginning with blacksmiths producing wrought iron goods. These tradespeople learned to heat up iron ore, and using a hammer-and-anvil process, the blacksmiths would remove impurities from the metal and produce a durable and malleable final iron

Iron billet. The iron blooms made by bloomery . smelting had to be smithed before they could be used, to remove trapped slag and air. Then the iron was shaped into objects or a form of trade iron, such as a billet, ingot or bar. This is a billet of iron excavated from a Roman settlement at Westhawk Farm in Kent

The IFCON process, developed by ISCOR in South Africa, is capable of producing steel directly from coal and iron ore. 1 In this process, coal and ore are added continuously to a channel type induction furnace containing a slag-metal bath. Electrical energy is supplied by the induction furnace for heating and stirring the bath

the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas or elemental carbon produced from coal. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e., without melting, as in the blast furnace

This process is the oldest direct reduction method. In this method, Thermal coal is mixed with iron ore as a reducing agent. Natural gas generates the required reduction temperature, and reduction is performed on Silicon Carbide (SiC) Crucibles in a tunnel furnace. Input iron ore: Hematite or magnetite iron ore in form of fine, preferably high
