Abstract

According to the problem that horizontal current in the metal pad of aluminum reduction cell induces waves of the electrolyte-metal interface, this paper reports on assessments of the horizontal current elimination effects by using slotted cathode and heightened collector bar as well as their combination. Computational fluid dynamics (CFD) modelling was applied to predict the current flow and the corresponding voltage drop across the electrolytic cell. The results show that both appropriate design schemes of slotted cathode and heightened collector bars can effectively reduce the maximum and average values of horizontal current density in the metal pad. Additionally, their combination effect of horizontal current reduction is better than each of both.
