Scrap metal is preheated by electrical radiant heating means. Volatiles driven off from the metal are mixed with air and are blown through conduits which constitute the electrical radiant heating elements. Combustion takes place inside the conduits and the products of combustion are directed through openings in the conduits onto the scrap metal. The temperature and pressure in the system is controlled by dampers arranged at each end of the conduits to vary gas recirculation.
