Abstract
The invention relates to a method and a device for supplying electric current to igneous electrolysis tanks. According to the method, each element, front and rear, of the upstream collector is divided into two parts, one end part 19-20 and the other the central part 17-18, and the tank is supplied by four risers, including two end risers 23-24 and two central risers 25-27 and 26-28; each central riser comprises two elements 25 and 27 located in the same plane parallel to the plane of symmetry (XX) and situated respectively at 1/4 and 3/4 of the length of the cathode, one 25 of these elements passing under the upstream tank 13. The invention applies to igneous electrolysis tanks and more particularly to those intended for the manufacture of aluminium.
