The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0 %. The EAF method, however, feeds recycled steel scrap through high power electric arcs (with temperatures of up to 1,650 degrees Celsius) to melt the metal and convert it into high quality steel.
