  • Anode assembly and associated production method
    Patent number: 10480089
    Abstract: The present invention relates to a manufacturing process for an anode assembly intended for cells for the production of aluminum by electrolysis, the anode assembly being of the type having an anode rod, a longitudinal member interdependent with one end of the anode rod and a carbon anode including a cavity in which is housed the longitudinal member, the method comprising a formation phase of at least one sealed area filled with sealing material and at least one unsealed area devoid of sealing material, said at least one unsealed area extending to one of the longitudinal ends of the longitudinal member.
    Type: Grant
    Filed: January 23, 2015
    Date of Patent: November 19, 2019
    Assignee: Rio Tinto Alcan International Limited
    Inventors: Yves Caratini, Denis Laroche, Julien Vallet, Bertrand Allano, Lyes Hacini

  • Electrolysis cell for the production of aluminum comprising means to reduce the voltage drop
    Patent number: 8500970
    Abstract: An electrolytic cell is suitable for production of aluminium, and includes at least one collector bar made of first metal and at least one complementary bar made of a second metal having an electrical conductivity greater than the first metal and arranged adjacent to one of the side faces of the collector bar so that the external end of the complementary bar is at a specified distance from a specified end face of the block. The second end terminates so as to limit heat losses from said cell. The cell makes it possible to obtain significantly lower voltage drops while avoiding excessive heat losses through the collector bars.
