Iron processing Definition, History, Steps, Uses, Facts - Britannica
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 (the 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.

Bessemer process - Wikipedia
The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.

Who invented the Bessemer Process, which converted iron ore
Railroad growth created a considerable steel market. The first railroads ran on wrought iron rails, which were too soft to be durable (not enough carbon). On some busy stretches, the wrought iron rails had to be replaced every six to eight weeks. Steel production was still laborious and costly, using vast amounts of charcoal, ore, and labor.

2019年9月18日 How steel is made. First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The ore-based process uses a blast furnace or smelter and the scrap-based process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster.
