建立了AP-30铝电解槽阴极块的有限元/优化模型，以确定阴极块的最佳形状。最佳形状是使阴极块表面上的电流密度尽可能均匀的设计，以便同时延长其寿命，最小化其能量消耗并最小化材料成本。结果表明，通过对集流棒的设计进行改进，阴极压降可降低93 mV，电池寿命可提高20%。
A finite element/optimization model was developed to determine the optimum shape of the cathode block of an AP-30 aluminum electrolysis cell. The optimum shape is the design that makes the electric current density on the surface of the cathode block as uniform as possible so as to simultaneously prolong its lifetime, to minimize its energy consumption and to minimize the cost of material. Results indicate that by making some changes in the design of the collector bar, the cathode voltage drop can be reduced by 93 mV and the lifetime of the cell can be increased by 20%.
