ELECTROLYTIC TREATING DEVICE FOR BELT-LIKE METAL

摘要

PROBLEM TO BE SOLVED: To provide an electrolytic treating device for a belt-like metal which can suppress the fluctuation in a plating coating weight by eliminating the biasing of the belt-like metal between electrode plates and can improve the quality of products and reduce a plating alloy cost. SOLUTION: This electrolytic treating device 10 is provided with a sink roll 15 for guiding the belt-like metal 13 within an electrolytic cell 12 containing an electrolyte 11 and is arranged with aperture of electrode plates 17a, 17b, 18a and 18b respectively on the inlet side and outlet side of the sink roll 15 across the belt-like metal 13. The electrode plate 18a on the sink roll 15 side of a pair of the electrode plates 18a and 18b arranged on the outlet side of the sink roll 15 is formed longer than the other electrode plate 18b.
