Abstract:
Method for the continuous chromium-plating of elongated members according to which an elongated member to be plated is advanced through at least one tubular-shaped chromium-plating anode into which an electrolytic solution is made to flow so as to allow the deposition of at least a layer of chromium on the bar as the latter is advanced through the anode, characterized by the steps of:supplying the electrolytic solution along the length of the chromium-plating anode by axially distributing a flow of electrolytic solution from the bottom to upwards, transversely with respect to the advancing direction of the elongated member, andcirculating the electrolytic solution through the chromium-plating anode, in a controlled condition and in a quantity sufficient for keeping the elongated member at a substantially constant chromium-plating temperature while the same elongated member is advanced into the electrolytic solution along the chromium-plating anode.
