Steelmaking Wikipedia

Basic oxygen steelmaking is a method of primary steelmaking in which carbonrich molten pig iron is converted into steel Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into steel The process is known as basic due to the chemical nature of the refractories—calcium oxide and magnesium oxide—that line the vessel to withstand the high
