A plurality of rectangular electrolytic cells are disposed in at least two rows of a side-by-side arrangement of cells. A first set of cathode bus bars extends along the outside of the short end of the cell facing the other row of cells. This set of bus bars, along with a second set of bus bars disposed beneath the cell, collect cathode current from the upstream long side of the cell. The second bus bars are positioned, and current through each set of bus bars is controlled, to minimize disruption of the molten bath due to circulation flow. |
