Methods for manufacturing steel have evolved significantly since industrial production began in the late 19th century. Modern methods, however, are still based on the same premise as the original Bessemer Process, which uses oxygen to lower the carbon content in iron.
Steelmaking is the process for producing steel from iron ore and scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium and vanadium are added to

Iron and Steel Manufacturing Industry Description and Practices Steel is manufactured by the chemical reduction of iron ore, using an integrated steel manufac turing process or a direct reduction process. In the conventional integrated steel manufacturing process, the iron from the blast furnace is con verted to steel in a basic oxygen furnace
Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as quot;ganguequot;. The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.
