BUS ARRANGEMENT OF ELECTROLYZER WINNING ALUMINUM Russian patent published in 2004 - IPC

FIELD: electrolytic production of aluminum. SUBSTANCE: invention can be employed to improve technical-and-economic index of electrolyzers with transverse location of bus arrangement thanks to modernization of bus arrangement circuit. Bus arrangement includes anode uprights positioned on input side of electrolyzer, collection buses with cathode bars passing along butts and under bottom of electrolyzer connected to them and to anode uprights of next electrolyzer in path of current. At least several collection buses on input side are placed in symmetry relative to axes of anode uprights perpendicular to longitudinal axis of electrolyzer and are so connected to cathode bars that current flows over collection buses in opposite directions from axes of uprights. EFFECT: enhanced current efficiency, reduced skewness of molten aluminum. 5 dwg, 1 tbl
