VERFAHREN ZUM MEHRLAGIGEN BESCHICHTEN VON STRANGFOERMIGEM GUT

摘要

A process is disclosed for coating elongated metallic materials, preferably strips or wires, with multiple layers, by applying different layers of metallic coating materials while the materials to be coated continuously run through a plant composed of several successive dippings with molten coating materials. In order to produce new corrosion-resistant coatings with improved properties and improved surfaces, the elongated metallic materials are led in a straight line through the plant and their temperature is regulated by means of the adjustable dipping temperatures of the different molten coating materials. The device used to implement the process has several successively arranged coating containers (4a, 4b) with through-channels (12) for the elongated metallic materials (B) located below the dipping level (h) and closed by hydromagnetic seals (13).
