Furnace consists of three separate chambers which are arranged in a cascade so that the melt can flow from one to the next. The first is for melting and extraction of iron scrap, the second for collection of the melt and for melting pure aluminium scrap, and the third is for refining. This furnace can process aluminium scrap both with and without iron admixtures. It has a high throughput, low metal losses and requires little labout. The first chamber at the highest level is charged with aluminium scrap, containing iron, by a belt conveyor after the cover has been shifted. The molten aluminium flows through a channel while the iron scrap is removed from the hearth through an opening on the side. L'invention concerne la métallurgie. Le four faisant l'objet de l'invention est du type comportant une chambre de fusion 1, une chambre de raffinage 3 et un dispositif pour le chargement des déchets dans la chambre de fusion 1, et est caractérisé en ce que, entre la chambre de fusion 1 et la chambre de raffinage 3 est prévue une chambre 2 d'accumulation du produit fondu, communiquant en permanence avec la chambre de fusion 1 et périodiquement avec la chambre de raffinage 3, toutes des chambres étant disposées en cascade de manière que le produit fondu passe successivement de l'une dans l'autre L'invention permet notamment de faire fondre aussi bien les gros déchets non dépouillés, contenant des pièces en fer avec obtention directe d'alliages de nuance prédéterminé.
