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 (). A natural flow of the liquid metal from the surface of the liquid seal is set up in an overflow compartment () made in the duct () and having an internal wall which extends the duct () in its lower part, and the level of liquid metal in the compartment () is maintained at a level below the surface of the liquid seal (). Also, a plant for implementing the process.

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 ().

Plant for the dip-coating of a metal strip

The subject of the invention is a nozzle (1) for introducing a liquid metal into a mold for the continuous casting of metals, of the type comprising a tubular first part (2), one end of which is intended to be connected to a vessel containing said liquid metal and the other end of which emerges in a hollow second part (4) of elongate shape, at least one portion of the internal space (3) of which is oriented approximately perpendicular to said tubular first part (2), said hollow part (4) having an outlet (5, 6) at each of its ends, as well as one or more outlet orifices (7-17) provided in its bottom (18) and/or its lateral walls, a bar provided with holes (22, 22', 23-34) being placed in the internal space (3) of said hollow part (4) so that the liquid metal necessarily passes via said holes (22, 22', 23-34) before passing through said outlet orifices (7-17), wherein said bar (19, 38, 39, 41, 43) includes, on at least one portion of the width of its upper face, a raised part (20, 37, 42, 44) whose top lies along the longitudinal horizontal axis of said hollow part (4), said holes (22, 22', 23-34) being distributed on each side of said top.

Nozzle for introducing liquid metal into a mold for the continuous

The subject of the invention is a nozzle for introducing liquid metal into a mold for the continuous casting of flat metal products, having two large walls and two side walls, of the type having at its lower end two outlet ports which are made in its lateral wall opposite each other and intended to send the liquid metal each toward a side wall of said mold, and at least two holes made in the bottom of said lower end, wherein a first group of said holes is arranged on one side of a longitudinal plane of symmetry of the nozzle, which plane includes the axes of the outlet ports, and a second group of said holes is arranged on the other side of said plane of symmetry.

Nozzle for introducing a liquid metal into a mold, for the continuous

The invention relates to a nozzle for introducing a liquid metal into a mold for continuous casting of metals, of the type comprising a tubular first part, one end of which is intended to be connected to a receptacle enclosing said liquid metal, and the other end of which opens into a hollow second part in which at least one portion of the internal space is oriented substantially perpendicularly to said tubular first part, said portion comprising at each of its ends at least one orifice intended to emerge into the casting space of said mold, which comprises an obstacle placed in the path of the liquid metal inside said tubular first part or in its extension, said obstacle consisting of at least one perforated component intended to divert the metal from its preferential trajectory inside the nozzle.
