  • Patent number: 11001931
    Abstract: The application is directed towards methods for purifying an aluminum feedstock material. A method provides: (a) feeding an aluminum feedstock into a cell (b) directing an electric current into an anode through an electrolyte and into a cathode, wherein the anode comprises an elongate vertical anode, and wherein the cathode comprises an elongate vertical cathode, wherein the anode and cathode are configured to extend into the electrolyte zone, such that within the electrolyte zone the anode and cathode are configured with an anode-cathode overlap and an anode-cathode distance; and producing some purified aluminum product from the aluminum feedstock.

  • Publication number: 20200305242
    Abstract: The present invention, in some embodiments, is a method the includes obtaining a sheet of a non-ferrous alloys as feedstock having a first edge and a second edge, heating the feedstock using a transverse flux induction heating system to form a heat treated product and concomitant with the heating step, cooling at least one of the first edge and the second edge of the feedstock by cross-flowing at least one fluid across the at least one of the first edge and the second edge of the feedstock.
