Abstract
(EN)
The present invention relates to a nozzle and a casting method comprising the steps of: providing a nozzle; injecting a melt into a container by using the nozzle; and controlling the flow of the melt injected into the container by circulating a part of the injected melt to the inner bore portion of the nozzle. By circulating at least a part of the melt injected into the container to the inside of the nozzle, the meniscus flow of the melt can be stabilized.
(FR)
La présente invention concerne une buse et un procédé de coulage comprenant les étapes consistant à : utiliser une buse ; injecter une matière fondue dans un récipient à l'aide de la buse ; et régler le débit de la matière fondue injectée dans le récipient en faisant circuler une partie de la matière fondue injectée vers la partie d'alésage interne de la buse. En faisant circuler au moins une partie de la matière fondue injectée dans le récipient vers l'intérieur de la buse, l'écoulement au niveau du ménisque de la matière fondue peut être stabilisé.
