Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel. The process is referred to as “basic” because of the pH of the refractories and the calcium oxide and magnesium oxide, which line the vessel to protect against the high temperature of molten metal. Secondary Steelmaking
