1A Manufacturing Process for Iron and Steel
The figure shows a flowchart of the integrated manufacturing process for iron and steel using the blast furnace and basic oxygen furnace (denoted BF and BOF hereinafter, respectively), which is presently the most commonly used method (51% of world steel production).Iron ore and steel production trends and material flows,01-10-2010· These figures are total iron ore and steel figures though, while a country may export billet or bars and import wire for example, depending on where it is produced most cheaply.

Iron ore and steel material mass flows in the world for the year 2006 (tonnages in short tons).Steelmaking - Wikipedia,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 (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.
