Basic oxygen steelmaking Wikipedia
Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitzsteelmaking or the oxygen converter process is a method of primary steelmaking in which carbonrich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into lowcarbon steel.
