Abstract
(EN)
A steel making system including a coupling for the supply of stirring gas to a ladle (10). The coupling includes a male member (6) mounted on a ladle car or stand (3) which is controllably actuable to move in a substantially horizontal plane between a first retracted position and a second extended position. The rear of the male member (6) is mounted on a universal joint (4) and its front is hung from springs (5). This mounting allows the male member to move in a vertical plane and makes it tolerant of misalignment between the ladle and the car or stand (3).
(FR)
L'invention concerne un système de fabrication d'acier comprenant un raccord permettant d'alimenter une poche(10) de coulée en gaz d'agitation. Le raccord comprend un élément mâle (6), monté sur un wagon-poche ou sur un chevalet porte-poche (3), dont peut actionner de façon contrôlée le déplacement, dans un plan sensiblement horizontal, entre une première position rétractée et une seconde position déployée. La partie arrière de l'élément mâle (6) est montée sur un joint universel (4) et sa partie avant est reliée à des ressorts (5). Ce montage permet à l'élément mâle de se déplacer dans un plan vertical, et de tolérer les défauts d'alignement entre la poche de coulée et le wagon ou le chevalet (3).
