UNIFORM ELECTROLYTIC TREATING DEVICE OF METALLIC STRIP

摘要

PURPOSE:To obtain a uniform high current density in a titled treating device by limiting the disposition of respectively specified numbers of current conducting rolls and insoluble anodes. CONSTITUTION:This electrolytic treating device of a metallic strip has non-conductive turn rolls 4 disposed above and below higher than the electrolyte 6 in an electrolytic cell so as to pass vertically a metallic strip 2 in the electrolytic cell, current conducting rolls 8 attached to the parts of the rolls 4 on which the strip 2 are wound and insoluble electrodes 10 provided on the outside circumference of the rolls 4. The electrolyte 6 is supplied into the gap between the strip 2 and the electrodes 10 through a header 16 and a jet port 18 so that the power feed and electrolysis treatment are accomplished in the above-described winding parts of the strip 2. 1-5 Pieces of the rolls 8(R) and 2-4 pieces of the electrodes 10(A) are used in this case and the arrangement thereof consists of any combination expressed by the formulas I -VII.
