Scrap metal and iron ore are melted with very hot electrodes (about 1,650 degrees Celsius). Oxygen blown into the furnace during the process removes impurities from the hot metal. The molten steel is then tapped into a ladle furnace where additives are mixed in to refine the composition of the steel and give it certain properties.
