By 1350 BC to 1100 BC, the production of ferrous metals from iron ore had spread to a wide geographic area.1 More than 3,000 years after this early beginning of the Iron Age, modern iron and steelmakers still use the same carbothermic process discovered by early ironmakers. However, this industry continues to develop incremental
Steelmaking – Wikipedia
Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.
