Basic Oxygen Furnace Steelmaking - Steel TechnologyAug 04,2020·Basic Oxygen Furnace (BOF) steel making or Basic Oxygen Furnace Steelmaking (BOS) or Linz-Donawitz-Verfahren steelmaking or the oxygen converter process is a method in which both molten pig iron and steel scrap are converted into steel with the oxidizing action of oxygen blown into the melt under a basic slag.Oxidation and decarburization of forgings during heating When the steel material is heated,the carbon on the surface and the oxidizing gas in the furnace react chemically,the phenomenon that the surface of the steel material and the carbon content decrease is called decarburization,a result of diffusion.
