铝电解槽的槽底电压降与其结构、阳极宽度和工艺状况有关,为250～450毫伏,占电解槽加热功率的6～11%。电解槽的能量参数和阴极装置工作的温度条件均取决于该值。因而,研究降低电压降的可能途径是合理的。早巳指出,槽底电压降的主要部分是 The voltage drop at the bottom of the aluminum reduction cell is related to its structure, anode width and process conditions, ranging from 250 to 450 millivolts, accounting for 6 to 11% of the cell heating power. The energy parameters of the cell and the temperature conditions at which the cathode device operates depend on this value. Therefore, it is reasonable to study possible ways to reduce the voltage drop. It has been pointed out earlier that the major part of the voltage drop at the bottom of the tank is
