In a basic oxygen furnace (see Fig 1), oxygen is blown through liquid pig iron, increasing its temperature and releasing carbon Pure oxygen is used as it improves the efficiency of the reaction between carbon and oxygen Hydrocarbon fuel injection (coal, natural gas, oil, and tar) is also used to increase temperature and speed throughput

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
