an apparatus and a method for manufacturing an electric chrome-plated steel strip of electrical chrome-plated steel strip

摘要

PROBLEM TO BE SOLVED: To provide a device for chromium electroplating of a steel strip, with adjustment of the concentration of metal impurities in a chromium plating tank; and a method of chromium electroplating.;SOLUTION: The device for manufacturing a chromium electroplated steel strip includes: a plating tank in which a steel strip is chromium electroplated; a drag-out tank in which chromium plating solution dragged out of the plating tank by an associated flow along with the transfer of the steel strip is collected; a drag-out storage tank in which the chromium plating solution collected in the drag-out tank is stored; a device which is separately connected to the drag-out storage tank so as to remove metal impurities in the stored chromium plating solution; and a chromium plating solution buffer tank connected between the plating tank and the drag-out storage tank, which allows the chromium plating solution to be circulated into the plating tank and returns the chromium plating solution stored in the drag-out storage tank to the plating tank.;COPYRIGHT: (C)2015,JPO&INPIT
