Abstract

A brief analysis is made of different approaches to controlling the energy balance of electrolytic cells and the composition of the electrolyte. The effect of various factors on the temperature characteristics of electrolytes is studied during the production of aluminum. The goals of the investigation as a whole were to optimize the parameters of the cell and create a program for controlling its energy balance by monitoring the working voltage and electrolyte-temperature distribution and automatically keeping these parameters within prescribed limits. The results obtained from the investigation can be used to develop and introduce a technology for automatically controlling the production of aluminum in electrolytic cells.
