A DEVICE AND A METHOD FOR CONTROLLING THICKNESS

摘要

A device and a method for controlling the thickness of a metallic coating on an elongated metallic element (1) formed by continuously transporting the element through a bath (2) of molten metal comprises at least one pair of electromagnetic wiper members (7a, 7b, 8a, 8b) and, associated therewith, a second wiper member (11) designed to apply to the element (1) a jet of gas with a target area essentially according to a line transversely of the element with respect to the direction of the transport path in order to assist the electromagnetic wiper member in the wiping of superfluous molten metal from the element .
