A cylindrical furnace lined with material capable of enduring high temperatures that produces molten steel by heating iron and steel scrap and other materials that are used as charge materials, using discharges of electricity from carbon-based conductors and direct-current electrical energy. This energy-efficient technology recovers the heat from the furnace off-gas by exhausting it through a shaft where the steel scrap is held prior to charging.
