<p>Continuous melting of lightweight shredded metal, e.g. in the recycling of aluminium can scrap, uses apparatus as shown in Figure 1, the scrap portions being fed into the top of a melting chamber (12) to be acted on by an upward flow of gases at controlled velocity, preferably recirculated from the top to the bottom by a fan (18), and heated to a temperature in excess of the metal melting point; the portions being borne in the flow within the chamber until they melt into denser droplets or globules which drop from the chamber to collect in a holding furnace (26). <IMAGE></p> |
