the conventional integrated steel manufacturing process, the iron from the blast furnace is con-verted to steel in a basic oxygen furnace (BOF). Steel can also be made in an electric arc furnace (EAF) from scrap steel and, in some cases, from direct reduced iron. BOF is typically used for high-tonnage production of carbon steels, while
Direct-reduced iron has about the same iron content as pig iron, typically 90–94% total iron (depending on the quality of the raw ore) so it is an excellent feedstock for the electric furnaces used by mini mills, allowing them to use lower grades of scrap for the rest of …
electric arc furnace was 31,9% (from total crude steel production). During the 2005-2014 period, participation of steel production via electric arc furnace was increased, for example, in Italy for 12,3%, in USA for 7,5%, in Russia for 14,3%, but a due to strong increase of steelmaking production in China mainly with oxygen blowing
