Method and installation of electrolytic tinning of a steel strip continuously moving in the electrodeposition unit

摘要

1. Method of electrolytic tinning of a steel strip (1) continuously moving in a deelectrodeposición unit (3) with insoluble anode (23) in an electrolyte and has a deelectrodisolución online (6) intended to recharge the reactor electrolyte in tin by selectively separating ions through unamembrana (10) electrodialysis or electrolysis dividing said electrodissolution reactor (6) in anodic uncompartimiento (6b) containing a first electrode (122b) connected to the positive pole of a circuit supply Ignition (12) into electric current and a cathode compartment (6a) having a second electrode (121a) connected to the negative pole of the same electrical circuit, for which a control member electrodissolution reactor enters into a first permutation depolaridad supply current electric each of the two electrodes, the body ensures control of permutation adjacent to the first way, a second perm utación dela electrolyte circulation between each of the two compartments electrodissolution reactor and unidadde electrodeposition and characterized in that - adjacent and periodic permutations polarity supply of electric current launidad electrodissolution and electrolyte circulation returns to the electrodeposition unit ensure unatoma continuous electrolyte in alternating cycles from one or other of the two compartments to be attributed to dichocompartimiento an anodic function electrodissolution using a soluble electrode, - the two alternating cycles of continuous shooting are defined by lengths similar.
