The invention concerns a tundish for continuous casting in a steel mill, equipped with at least one tube changer (18). The changer has a frame (20) mounted under the tundish (2), at least one fixed plate (8) and a tube (28), having a plate (30) at its upper part, means (36) for applying the plate (30) of the tube (28) against the fixed plate (8), their surface in contact forming a junction plane (34). The junction plane (34) is inclined at a nonzero angle .alpha. with respect to the horizontal. The new tube (28) passes from the introduction position to the casting position and the worm tube from the casting position to the evacuation position by a sliding movement on the junction plane (34), following a trajectory at least partially nonrectilinear, the combination of the angle of inclination .alpha. of the junction plane, dimensions of the tubes (30) and the trajectories of these latter being such that the tubes (30) avoid the casting mold (42) during a tube change.
L'invention concerne un panier de coulée en continu dans une aciérie, équipé d'au moins un changeur (18) de tube. Le changeur a un cadre (20), monté sous le panier de coulée (2), au moins une plaque fixe (8) et un tube (28) ayant une plaque (30) dans sa partie supérieure, un moyen (36) pour appliquer la plaque (30) du tube (28) contre la plaque fixe (8), leurs surfaces en contact formant un plan de jonction (34). Le plan de jonction (34) est incliné à un angle non nul .alpha. par rapport à l'horizontale. Le nouveau tube (28) passe de la position d'introduction à la position de coulée et le tube usé de la position de coulée à la position d'évacuation, par un mouvement coulissant sur le plan de jonction (34), suivant une trajectoire au moins partiellement non rectiligne, la combinaison de l'angle d'inclinaison .alpha. du plan de jonction, des dimensions des tubes (30) et des trajectoires de ces tubes étant telle que les tubes (30) évitent la lingotière (42) durant le changement.
