Abstract
A method for hot-dip coating of a steel strip running in a bath of liquid metal such as zinc, or metal alloy contained in a pan is provided. Dross which are formed during the coating and float at the surface of the bath are moved away from the surface of the strip by at least one inductor. Each inductor produces a sliding electromagnetic field oriented along a given direction and generates a magnetomotive force, and the magnetomotive forces displaced the dross towards a container intended to collect them and/or towards an area of the surface of the bath from which they are discharged. For at least one of the inductors, the direction of the respective sliding electromagnetic field is reversed intermittently so as to modify the flows of the dross inside the pan. A hot dip coating facility is also provided.
