What is the Basic Oxygen Steelmaking Process
The basic highlights of the BOS process are the partial oxidation of the phosphorus carbon silicon and manganese present in pig iron and the going with a decrease in the sulphur level. BOS is a primary steelmaking process for changing over liquid pig iron into steel by blowing oxygen through a lance over the molten pig iron inside the converter.
