ABSTRACT:
The invention relates to a circuit for electrical connection between two successive cells of a series or row, designed for the production of aluminium by electrolysis of alumina dissolved in molten cryolite by the Hall-Heroult process at an intensity of at least 150 kA and possibly attaining from 500 to 600 kA. The circuit for the electrical supply of the cells comprises, in addition to the circuit 8 for the supply of electrolysis current, a distinct circuit 17 for correcting and balancing the magnetic fields which is formed by conductors which are substantially parallel to the axis of the series and are traversed by a direct current in the same direction as the electrolysis current which creates, in the cells, a vertical correcting magnetic field directed downwards close to the left-hand heads of the cells and directed upwards close to the right-hand heads of the cells. The total current J2 traversing the magnetic correcting circuit is at most equal to the electrolysis current J1 and is preferably between 4 and 80% of J1.
