Abstract

Modeling of the internal contact connections resistance of electrolysis plants is important to a problem solution of energy savings in companies with energy-intensive production with rated currents of 40-150 kA that is a complex mathematical problem. In electrolytic plants, suppression grids, steeped into the solution in the electrolytic bath, are used as electrodes, and their deformation leads to an uneven current distribution on the electrode surface and insufficient performance of the electrolyser. It is suggested to produce electrodes of perforated steel sheets. Using calculation of complex electric fields, a method for optimizing the geometrical characteristics of the electrolysis baths has been developed, in order to reduce their internal resistance and even current distribution in them. The value of the electrolyser’s conductivity has been obtained, depending on apertures radius, the distance between their centers and sheets’ thickness. The electrodes modeling and a study of their conductivity have been performed; conductivity values of the electrolysis bath have been obtained, depending on the changes in these parameters.
