Basic Oxygen Furnace (BOF) | NIPPON STEEL ENGINEERING

A basic oxygen furnace is a reactor in which oxygen is blown through molten pig iron that is heated to approximately 1,600℃ to convert it into steel. As the basic oxygen furnace shell is exposed to severe high-temperature conditions during use, its material experiences gradual degradation leading to thermal deformation and cracking that ...

Steelmaking - Wikipedia

Basic oxygen steelmaking is a method of primary steelmaking in which carbon-rich 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 .
