Description

Steel making is the process for producing steel from iron ore and scrap. In steel making, impurities such as nitrogen, silicon, phosphorus, Sulphur and excess carbon are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygen, and entrained impurities (termed “Inclusions”) in the steel is also important to ensure the quality of the products cast from the liquid steel. The module takes us through the best steel making practices in an industry.
