Abstract: 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.
