Abstract
A method and device disclose how to drain a liquid coating metal from the two sides of a running steel strip. The method transfers a strip coated with a liquid coating metal, as it runs at the tank outlet, from a region not subjected to a magnetic field to another region subjected to a static magnetic field generated between the poles of magnetic members arranged opposite each other on either side of the strip and having field lines, or at least a main shell of the field lines, intersecting with the strip over at least one minimum longitudinal extent so that the liquid coating metal is correlatively subjected to a magnetic field variation generating on the liquid metal a force opposite to the running direction. Due to the low field variation, this magnetic braking effect generates little Foucault current in the strip.
