A process for the continuous dip-coating of a metal strip () in a tank () containing a liquid metal bath (), in which process the metal strip () is made to run continuously through a duct (), the lower part of which is immersed in the liquid metal bath (), in order to define with the surface of the bath a liquid seal (). In the region where the strip () leaves the liquid metal bath (), the liquid metal is isolated from the surface of the bath in an isolating enclosure (), the metal oxide particles and intermetallic compound particles are recovered by the liquid metal flowing from this region into the enclosure (), and the particles are extracted from this enclosure (). Also, a plant for implementing the process.

A process for the continuous dip-coating of a metal strip () in a tank () containing a liquid metal bath (), in which process the metal strip () is made to run continuously through a duct (), the lower part () of which is immersed in the liquid metal bath () in order to define with the surface of the bath a liquid seal (). A natural flow of the liquid metal from the surface of the liquid seal () is set up in two overflow compartments () made in the duct () and each having an internal wall which extends the duct () 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 (). A plant for implementing the process.

Method and installation for hot process and continuous dip coating of a metal strip

A process for the continuous dip-coating of a metal strip () in a tank () containing a liquid metal bath (), in which process the metal strip () is made to run continuously through a duct (), the lower part () of which is immersed in the liquid metal bath () in order to define with the surface of the said bath a seal ().

Method and installation for dip coating of a metal strip

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