A hypothetical drained cell model retrofitted from a 160kA Hall-Heroult cell was set up to calculate the current distribution in the cathode when the anode bottom and cathode top surfaces were declivous. Two half anode-cathode slice thermo-electrical models with the collector bars installed slopingly or horizontally were adopted to calculate the potential drop and electricity distribution of the cathode.

摘 要：将某厂现有的160kA Hall-Heroult铝电解槽改造成导流槽后，在阴极上表面和阳极底面呈斜坡状的条件下，计算了采用不同阴极导杆安装方式时阴极的电位和电流分布，即通过建立导流槽内部从阳极到阴极的一个半切片电热场模型，用有限元法分别对水平和平行于阴极斜坡两种不同导流槽阴极导杆的安装方式下阴极电位和表面电流密度分布进行了计算。
