The apparatus of the present invention includes a molten metal vessel system for casting molten metal, the system comprising: (a) a vessel (1) containing molten metal (2) adapted to contain and dispense the molten metal (2) for casting, the vessel (1) having interior surfaces (8) and the molten metal forming an upper surface (9); (b) a submerged entry nozzle (3) exiting below the upper surface (9); and (c) a surface and/or a submerged flow modifier member (7, 11) disposed between at least one of the interior surfaces (8) and the submerged entry nozzle(3). The surface and/or submerged flow modifiers (7, 11) work to impede the formation of waves in the upper surface (9) of the molten metal (2). The present invention also includes a method for improving the quality of a continuous casting process.
L'invention concerne un système de cuve de coulée pour le moulage de métal fondu, qui comprend: (a) une cuve (1) de métal fondu (2) contenant et distribuant le produit (2) de moulage, cette cuve (1) ayant des surfaces intérieures (8) et le métal fondu formant une surface supérieure (9); (b) une buse d'entrée immergée (3) sous la surface supérieure (9); et (c) un modificateur de flux immergé et/ou en surface (7, 11) entre au moins une des surfaces inférieures (8) et la buse immergée (3). Le modificateur de flux immergé et/ou en surface (7, 11) empêche la formation d'ondes à la surface supérieure (9) du métal fondu (2). L'invention concerne également un procédé permettant d'améliorer la qualité du processus de moulage en continu.
