METHOD FOR FORMATION OF SELF-BURNING ANODE OF ALUMINIUM ELECTROLYZER WITH UPPER CURRENT SUPPLY Russian patent published in 1997 - IPC

Abstract RU 2085623 C1

FIELD: electrolytic aluminium production. SUBSTANCE: charging of anode mass with elevated content of binder designed for transposition of contacting fingers is performed directly into projection of disposition of longitudinal sets of current-supply fingers in anode plane defined with planes passing outside internal and external sets of fingers of each longitudinal sides of electrolyzer, whereas remaining surface of anode is charged with "dry" mass. Charging of anode mass with elevated content of binder may also be performed in direction from internal sets of fingers to external ones after charging "dry" mass, upper level of anode mass in projection of fingers being maintained higher than level of remaining part of anode. EFFECT: reduced usage of anode mass, reduced power consumption, coal foam yield, and increased productivity of electrolyzer. 3 cl, 2 dwg, 2 tbl
