<p>A method for dip coating a steel strip (16) moving in a liquid bath (9) of metal, such as zinc, or of metal alloy contained in a tank (15), by which the mattes which are formed during the coating and float on the surface (10) of the bath (9) are removed from the surface of the strip (16), by means of at least one inductor (11-15), each inductor (11-15) producing a travelling electromagnetic field oriented in a given direction and generating a magnetomotive force, all of said magnetomotive forces moving said mattes towards a container (19) intended to collect said mattes and/or towards an area (25) of the surface (10) of the bath (9) from where they are discharged, characterised in that, for at least one of said inductors (11-15), said direction of the travelling electromagnetic field thereof is intermittently reversed in such a way as to modify the flows of mattes inside the tank (15). Facility for implementing said method.</p> |
