Method for electrolytically producing a metal band

Abstract

Abstract THE METHOD RESIDES IN DEPOSITING THE METAL ELECTROLYTICALLY ON THE SURFACE OF A CATHODE FROM AN ELECTROLYTIC SOLUTION, WITH THE CURRENT DENSITY BEING SUCCESSIVELY VARIED IN A PLURALITY OF STAGES: DURING THE FIRST ONES OF THESE STAGES THE CURRENT DENSITY IS MAINTAINED WITHIN A RANGE FROM 1,000 TO 5,000 A./SQ. M., DURING THE LAST STAGE BUT ONE THE CURRENT DENSITY IS MAINTAINED WITHIN A RANGE FROM 5,000 TO 10,000 A./SQ. M. FOR A PERIOD FROM 1 SECOND TO 300 SECONDS, DURING THE LAST STAGE THE CURRENT DENSITY IS MAINTAINED WITHIN A RANGE FROM 4,000 TO 50,000 A./SQ. M. FOR A PERIOD FROM 1 SECOND TO 200 SECONDS, THE ELECTROLYTIC SOLUTION BEING POSITIVELY AGITATED DURING ALL SAID STAGES EXCEPT THE LAST ONE. THE APPARATUS COMPRISES AT LEAST THREE ANODE PLATES ARRANGED ABOUT THE PERIPHERY OF THE CATHODE DRUM AND RAIDIALLY SPACED THEREFROM WITHIN THE BATH CONTAINING THE ELECTROLYTIC SOLUTION, THE ANODE PLATES BEING CONNECTED TO THE INDIVIDUAL POWER SUPPLY SOURCES. THE TWO ANODE PLATES, WHICH ARE THE LAST ONES IN THE DIRECTION OF THE PROGRESS OF THE METAL BAND, HAVE THE RATIO OF THE RESPECTIVE SURFACE AREAS THEREOF WITHIN A RANGE FROM 15:1 TO 5:1. THE INTERELECTRODE SPACE, PERTAINING TO THE LAST ONE OF THESE ANODE PLATES, IS SEPARATED BY A PARTITION FROM THE REST OF THE INTERNAL SPACE OF THE BATH.
