Abstract

The invention relates to a method and a device for coating the surfaces of, in particular, strip-like material, for example, a non-ferrous metal strip or a steel strip, with at least one metallic coating by running through at least one container filled with the liquid melt coating material. The metal strip for coating runs through the molten bath of coating material within the container from bottom to top, suitable guide means are provided for the above. The sealing of the container base is achieved by means of circumferential permanent magnets.

Claims (10)
