Process of steelmaking | Tata Steel
When sufficient hot metal has formed at the bottom of the furnace, we drill open the furnace and tap the iron. The hot metal is collected in torpedo-shaped train waggons and is then ready for transport to the BOS (Basic Oxygen Steelmaking) plant next door. The converter in the BOS Plant turns the pig iron into steel.
Steps in the Modern Steelmaking Process
The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5%. The EAF method, however, feeds recycled steel scrap through high-power electric arcs (with temperatures of up to 1,650 degrees Celsius) to …
Iron processing
Iron processing - Smelting, Refining, Alloying: 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 …

Iron- and Steel-Making Process | SpringerLink
Iron is extracted in the form of metallic iron (Fe) by reducing the oxide ores with a reducing agent. The principal agents commonly employed to serve this reduction process are the naturally occurring forms of carbon such as coke, charcoal and coal. In order to extract the iron, Fe (55–60%)-rich ore is usually used.
