Present Status of Steel Industry: Plain carbon steels are produced principally by the following routes: 1) Blast furnace→ Basic oxygen furnace →Ladle treatments→continuous casting→Rolling →flat or long products. Adopted by Integrated Steel Plants 2) Electric Arc Furnace→ Ladle treatments→Continuous casting→Rolling →Mostly long products but occasionally flat products. Adopted by Mini Steel Plants Alloy and special steels are produced by route 2. Some plants employ Argon-Oxygen-Decarburization process instead of Electric Arc Furnace Top steel producers in the world in the year 2010-2011
