The Making of Iron & Steel SEAISI

Originally most steel was produced by the "Bessemer" and "open hearth" processes but these have been replaced by the more modern "basic oxygen steelmaking" (BOS) and "electric arc furnace" (EAF) processes. The BOS process uses pure oxygen, injected by a lance, for refining the relatively impure hot metal (and scrap is used for temperature control).Онлайн-запрос

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.
