Steps in the Modern Steelmaking Process

Aug 21, 2020· Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten iron—also referred to as hot metal—still contains 4-4.5% carbon and other impurities that make it brittle.Steelmaking Process - an overview | ScienceDirect Topics,During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).Iron and Steel Manufacturing,In the BOF process, coke making and iron making precede steel making; these steps are not necessary with an EAF. Pig iron is manufactured from sintered, pelletized, or lump iron ores us-ing coke and limestone in a blast furnace. It is then fed to a BOF in molten form along with scrap metal, fluxes, alloys, and high-purity oxygen to manufacture,
