PROCEDURE OF REPLACEMENT OF ANODES IN ELECTROLYZERS PRODUCING ALUMINUM WITH SELF-BAKED ANODES Russian patent published in 2002 - IPC

FIELD: non-ferrous metallurgy. SUBSTANCE: invention deals with replacement of used self-baked anodes in electrolyzers. Procedure of replacement of anodes includes consistent replacement of anodes positioned on side opposite to longitudinal axis of electrolyzer. Anodes are replaced when difference in time of operation of any pair of anodes located one opposite another in opposite rows relative to longitudinal axis of electrolyzer is constant and equal to half-time of complete cycle of replacement of all anodes installed in electrolyzer and difference in time of operation of anodes located on both sides of any anode in longitudinal row amounts to one or two time intervals between replacement of anodes replaced in sequence. EFFECT: diminished harmful effect of operation of replacement of anodes on magnetic, hydraulic and dynamic stability of electrolyzer and formation of uniform and stable thermal field in its working zone. 1 dwg
