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. Secondary steelmaking involves treating the molten steel produced from both BOS and EAF routes to adjust the steel composition.
