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.
Blast furnace process tecscience
Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent.The carbon is fed to the blast furnace in the form of coke (pyrolyzed coal) from the coking plant.At sufficiently high temperatures, the carbon can participate directly in the
