How is pig iron converted into steel ? - Find 2 Answers ...

Iron to Steel. Fill a crucible with pig iron and carbon. Carbon can be made from charcoal or charred organic material such as bone or wood. The final carbon content of the steel is nearly impossible to predetermine, but filling the crucible three-quarters full with steel and the rest carbon is a good start.

The conversion of pig iron to steel frequently req toppr.com

The conversion of pig iron to steel frequently requires the addition of (I) oxygen or iron oxide and (II) transition elements.Iron oxide or oxygen oxidizes the impurities such as silicon and manganese which are then removed in the form of slag.Transition metals such as manganese serve as deoxidizer and reduce FeO (if any). Also Mn makes steel harder and increases its tensile strength.
