摘要：: <p>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 ( 13 a) of which is immersed in the liquid metal bath ( 12 ) in order to define with the surface of the bath a liquid seal ( 14 ). A natural flow of the liquid metal from the surface of the liquid seal ( 14 ) is set up in two overflow compartments ( 25, 29 ) made in the duct ( 13 ) and each having an internal wall which extends the duct ( 13 ) in its lower part, and the level of liquid metal in the compartments is maintained at a level below the surface of the liquid seal ( 14 ). A plant for implementing the process.</p>
