An apparatus for the smelting of aluminum includes a melting furnace that is separate from and free of permanent interconnection with an electrolytic cell. The melting furnace is preferably an induction melting furnace that is designed for optimum heating and intermixing of a cryolite electrolyte and alumina, and the electrolytic cell is preferably designed for electrolysis of alumina without regard for heating, mixing or dissolving requirements. Methods for operating the apparatus are also described.
L'invention concerne un appareil de fusion d'aluminium comprenant un four de fusion séparée et dépourvu d'interconnexion permanente avec une cellule d'électrolyse. Le four de fusion est, de préférence, à induction et conçu de manière à permettre un chauffage optimal ainsi que le mélange d'un électrolyte cryolitique et d'une alumine. La cellule d'électrolyse est, de préférence, conçue pour l'électrolyse de l'alumine, abstraction faite des nécessités de chauffage, de mélange ou de dissolution. L'invention concerne enfin des procédés destinés à mettre en oeuvre cet appareil.
