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 (the 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. limiting dissolved gases such as nitrogen and oxygenand entrained i · text under ccbysa licensesteel manufacturing process slidesharestep 2 steel making the steel making process is shown in figure 2. vanadium recovery before conversion into steel, vanadium is recovered from the molten iron. this is done firstly because of the value of the vanadium rich slag produced (15% vanadium as v2o5) and secondly because a high vanadium content can make the steel too hard.udc 669 . 184 . 244 . 66 621 . 746 . 047 development ofcient steelmaking process which can offer a wide variety of highgrade steel.
