    • The invention relates to an aluminum smelter, including: (i) a series of electrolytic cells (2) including an anode (9), a cathode, and a casing having a side wall (7a) and a bottom wall, each cathode including at least one cathode outlet (12); (ii) a main electrical circuit through which an electrolytic current passes, and which includes an electrical conductor (14) connected to each cathode outlet (12) of a cell N, and to the anode (9) of a cell N+1; and (iii) a means for stabilizing the electrolytic cells (2), which is provided in the form of either a secondary electrical circuit (5, 6) or a cathode having a crenulated surface. One of the cathode outlets (12) of the cell N passes through the bottom wall of the casing. Each electrical conductor (14) extends from each cathode outlet (12) of the cell N to the cell N+1, and the electrolytic current passes therethrough only in an upstream-to-downstream direction during the operation of the electrolytic cells N and N+1 (2).
    • 本发明涉及一种铝熔炉,包括:(i)包括阳极(9),阴极和具有侧壁(7a)和底壁的壳体的一系列电解池(2),每个阴极包括 至少一个阴极出口(12); (ii)电解电流通过的主电路,其包括连接到电池N的每个阴极出口(12)和电池N + 1的阳极(9)的电导体(14); (iii)用于稳定电解池(2)的装置,所述装置以二次电路(5,6)或具有小圆齿表面的阴极的形式提供。 单元N的阴极出口(12)中的一个穿过壳体的底壁。 每个电导体(14)从电池N的每个阴极出口(12)延伸到电池N + 1,并且电解电流在电解电池N和N的操作期间仅在上游至下游方向上通过 +1(2)。
