Abstract
(EN)
The present invention comprises: a first nozzle having a movement route of a molten metal formed therein; a second nozzle which is positioned at one side of the first nozzle and in which a movement route of the molten metal is formed, wherein the movement route can be interconnected to the movement route inside the first nozzle; and a sealing member installed such that at least a part of the sealing member can move between the nozzles in accordance with the pressure of a space between the nozzles. Therefore, the present invention can suppress or prevent outside air from flowing into the movement routes of the molten metal.
(FR)
La présente invention comprend : une première buse comportant en son sein un trajet de circulation d'un métal en fusion; une seconde buse qui est positionnée sur un côté de la première buse et dans laquelle est formé un trajet de circulation de métal en fusion, le trajet de circulation pouvant être raccordé au trajet de circulation présent à l'intérieur de la première buse; et un élément d'étanchéité installé de sorte qu'au moins une partie de l'élément d'étanchéité puisse se déplacer entre les buses en fonction de la pression d'un espace entre les buses. Par conséquent, la présente invention peut supprimer ou empêcher l'air extérieur de s'introduire dans les trajet de circulation du métal en fusion.
