METHOD AND DEVICE FOR ELECTROLYTIC TINNING OF CONTINUOUSLY MOVING STEEL STRIP IN ELECTRODEPOSITION MODULE

摘要

FIELD: metallurgy.;SUBSTANCE: method is implemented by means of the device in electrodeposition module (3) with insoluble anode (23) in electrolyte and in-line located electrodissolution reactor (6) designed for refilling of the electrolyte with tin ions by selective separation through diaphragm (10) of electrodialysis or electrolysis, which divides the above reactor (6) into anode compartment (6b) containing the first electrode (122b) connected to positive pole of electric current supply circuit (12), and cathode compartment (6a) containing the second electrode (121a) connected to negative pole of the same electric circuit. The first switching of polarity of electric current supply to each of the two electrodes is performed by means of reactor (6) control member. Besides, immediately after the first switching, the second switching of electrolyte circulation is provided between each of the two reactor (6) compartments and module (3). Continuous selection of electrolyte with alternating cycles is provided from this or that compartment, thus providing the above compartment with anodic function of electrodissolution by means of a soluble electrode; besides, both alternating cycles of continuous selection are performed with similar durations.;EFFECT: providing continuous electrolyte refilling.;26 cl, 7 dwg
