Abstract

An electromagnetic device for coating flat metal products by means of continuous hot dipping in a small molten coating bath, arranged over strip guiding rollers, the device being adapted not only to contain the molten coating metal in the bath but further to substantially eliminate leakages and dripping through the lower opening at the bottom of the container, for the strip passing, by means of particular electromagnetic components.
