ABSTRACT:
A process for the continuous dip-coating of a metal strip (1) in a tank (11) containing a liquid metal bath (12), in which process the metal strip (1) is made to run continuously through a duct (13), the lower part (13a) of which is immersed in the liquid metal bath (12) in order to define with the surface of the said bath a seal (14). A natural flow of the liquid metal from the surface of the liquid seal is set up in an overflow compartment (25) made in the duct (13) and having an internal wall which extends the duct (13) in its lower part, and the level of liquid metal in the compartment (25) is maintained at a level below the surface of the liquid seal (14). Also, a plant for implementing the process.
