Abstract

Плавильная установка получения алюминия, содержащая: (i) последовательность электролизных ячеек (2), содержащих анод (9), катод и кожух, снабженный боковой стенкой (7а) и дном, причем каждый катод содержит по меньшей мере один катодный вывод (12), (ii) основную электрическую цепь, по которой течет ток электролиза, содержащую электропровод (14), соединенный с каждым катодным выводом (12) электролизной ячейки N и с анодом (9) электролизной ячейки N+1, (iii) средство для стабилизации электролизных ячеек (2), выбранное из вторичной электрической цепи (5, 6) или применении катода с зубчатой поверхностью. Один из катодных выводов (12) электролизной ячейки N проходит через дно кожуха; каждый электропровод (14) идет от каждого катодного вывода (12) электролизной ячейки N в направлении электролизной ячейки N+1, и во время работы электролизных ячеек (2) N, N+1 ток электролиза течет через них только в направлении от переднего по схеме к заднему по схеме.An aluminum smelting plant containing: (i) a sequence of electrolysis cells (2) containing an anode (9), a cathode and a housing provided with a side wall (7a) and a bottom, each cathode containing at least one cathode outlet (12), (ii) the main electrical circuit through which the electrolysis current flows, containing an electrical wire (14) connected to each cathode terminal (12) of an electrolysis cell N and an anode (9) of an electrolysis cell N + 1, (iii) means for stabilizing electrolysis cells (2) selected from a secondary electrical circuit (5, 6) or approx Cathode with a serrated surface. One of the cathode leads (12) of the electrolysis cell N passes through the bottom of the casing; each electric wire (14) goes from each cathode lead (12) of electrolysis cell N in the direction of electrolysis cell N + 1, and during operation of electrolysis cells (2) N, N + 1, the electrolysis current flows through them only in the direction from the front one according to the scheme to the back of the scheme.
