<p>PURPOSE:To recover nickel incorporated in a plating solution after changing over. CONSTITUTION:In continuous electroplating equipment by alternately plating zinc and zinc aluminum on a steel strip by using an insoluble anode, this device is constituted by providing a solid-liquid separating means 5 to separate a sludge in the plating solution at a circulating pipe line passage connecting a zinc dissolving vessel 3 to replenish zinc ion by dissolving metal zinc in the plating solution with a zinc plating solution circulating tank 6, a transferring means 7 to transfer the separated sludge and a redissolving vessel 7 having a stirring device 8 to charge the transferred sludge into the zinc nickel plating solution to redissolve.</p> |
