ABSTRACT:
In electrolytic cells for producing aluminum in a side-by-side arrangement, a number of cathode bus bars connected to cathode current collector bars projected from upstream long side of each electrolytic cell are connected to at least one rising bus bars provided at upstream long side of an adjacent electrolytic cell provided on downstream side through at least one cathode bus bars provided in the space below the relevant cell and in parallel to the axial line of a row of electrolytic cells; the remaining number thereof are connected to rising bus bars provided at short ends of the adjacent electrolytic cell on the downstream side through cathode bus bars extending along outsides at the short ends of the relevant electrolytic cell, a number of cathode bus bars connected to cathode current collector bars projected from downstream long side of each electrolytic cell are connected to at least one rising bus bar provided on upstream long side of the adjacent electrolytic cell on the downstream side, and the remaining number thereof are connected to rising bus bars provided at the short ends of the adjacent electrolytic cell on the downstream side through cathode bus bars extending along outsides at the short ends of the adjacent electrolytic cell on the downstream side. Occurrence of circulating flow phenomena in molten aluminum layer in the cells can be suppressed to improve the current efficiency in the production of aluminum.
