CA 2706461

The invention pertains to a method for manufacturing a strip (1) of metal, particularly of steel, wherein liquid metal is delivered to a solidification section (3) from a delivery vessel (2), and wherein the cast metal solidifies along the solidification section (3). In order to achieve an optimal strip quality without damages, the inventive method proposes that liquid metal is delivered to a first location (4) of the solidification section (3) that is realized in the form of a horizontally extending conveyor element, and in that the solidified metal departs the conveyor element (3) at a second location (5) that is spaced apart from the first location in the transport direction (F), wherein means (6, 7) for maintaining the mass flow of the strip departing the solidification section (3) and/or the tension in the strip at a desired value are provided at or downstream of the second location (5) referred to the transport direction (F) . The invention furthermore pertains to a device for manufacturing a strip of metal.

L'invention concerne un procédé de fabrication d'une bande (1) de métal, notamment en acier, selon lequel du métal liquide sortant d'un godet de chargement (2) est amené sur une ligne de solidification (3), le métal coulé se solidifiant le long de cette ligne de solidification (3). L'invention vise à obtenir une bande de qualité optimale, sans endommagements. A cet effet, le métal liquide est amené en un premier emplacement (4) de la ligne de solidification (3) se présentant sous forme d'un élément de transport s'étendant à l'horizontale, et le métal solidifié quitte l'élément de transport (3) en un deuxième emplacement (5) séparé dans le sens de transport (F), des moyens (6,7) étant disposés sur ou derrière ce deuxième emplacement (5), dans le sens de transport (F), pour maintenir le débit massique de la bande à la sortie de la ligne de solidification (3) et/ou pour maintenir la tension dans la bande à un niveau souhaité. L'invention porte également sur un dispositif destiné à la fabrication d'une bande de métal.
