The Steel Story

A water-cooled copper tube called an oxygen lance blows pure oxygen (>99%) into molten iron – this reacts with the carbon, forming CO and CO2 which dissolve into the slag, out of the steel. If Basic Oxygen Steelmaking replaced the Bessemer Process, it was the Electric Arc Furnace (EAF) which replaced many Blast Furnaces.
