Iron and Steel Manufacturing - IFC

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 ...

Leading Iron and steel processors Iron Steel

Steel Making is often a complicated process of converting iron ore into Steel. In general, Steel Making is the second step in producing steel from the Iron ore, here the impurities are removed from the Raw iron ore and some elements are added to produce the steel which is required. Modern steelmaking is often divided into two parts.

Scrap metal and iron ore are melted with very hot electrodes (about 1,650 degrees Celsius). Oxygen blown into the furnace during the process removes impurities from the hot metal. The molten steel is then tapped into a ladle furnace where additives are mixed in to refine the composition of the steel and give it certain properties.
