Analysis of current distribution of electrode change operation in aluminium electrolysis based on equivalent circuit computer numerical

Abstract The development of industrial aluminium electrolytic cells towards higher series currents and a larger number of anodes, coupled with the fact that China has made more restrictions on high energy-consuming industries, has placed higher demands on the management of the aluminium electrolytic industry. In this study, a digital twin model of the electrolytic cell based on the idea of equivalent circuits was constructed using Matlab/Simulink software to simulate the electrode change operation and to study its effect on the change of current field. It is shown that the electrolysis temperature and the change of ACD caused by horizontal current have an effect on the current distribution.
