The present invention concerns stopper rod system for use in a metallurgical vessel, comprising a stopper rod and a nozzle. At least one of the stopper rod nose (42,56) and the internal surface of the nozzle bore comprise (43,62) a plurality of ripples that are arranged such that the size of a flow channel between the stopper rod nose and the internal stopper rod when the stopper rod system is in an open position discontinuously increases in size as a function of the distance downstream from the point of contact between the stopper rod and the nozzle.

La présente invention porte sur un système de tige de butée destiné à être utilisé dans une cuve métallurgique, ce système comprenant une tige de butée et un ajutage. Au moins un embout de la tige de butée et la surface interne du trou de l'ajutage comprend une pluralité de cannelures qui sont disposées de sorte que la dimension du canal d'écoulement entre l'embout de la tige de butée et la tige de butée interne, lorsque le système de tige de butée est en position ouverte, augmente en taille irrégulièrement en fonction de la distance en aval du point de contact entre la tige de butée et l'ajutage.
