The Steel Manufacturing Process - How is Steel Made?
To purify the steel, the furnace then blasts in oxygen, and lime and fluorspar are added. These substances combine with the steel's impurities, turning into slag. The slag then floats to the top of the molten steel where it is removed, leaving behind the pure steel. The EAF method is the most common steel production method today.
