Abstract
The subject of the invention is a plant for the continuous dip-coating of a metal strip (1), of the type comprising a tank (11) containing a liquid metal bath (12), a duct (13) through which the metal strip (1) runs and the lower end (13a) of which duct (13) is extended by at least two internal walls (20; 22) each located on one side of the strip (1) and directed towards the surface of the metal bath (12) in order to form at least one compartment (21; 23) for recovering the metal oxide particles and intermetallic compound particles. The duct (13) has a fixed upper part (30) and a movable lower part (31) joined together by a deformable element (32) and means (35) for positioning the movable lower part (31) with respect to the metal strip (1).
