摘要

Coupling device for reversibly coupling a ladle shroud to a collector nozzle, self-supported ladle shroud, kit thereof and method for coupling a ladle shroud to a collector nozzle. The present invention concerns a coupling device (34) fixed to a ladle shroud (111) for reversibly coupling an inlet orifice (115a) of said ladle shroud to a collector nozzle (112) fixed to the outside of a bottom floor of a ladle (11) in a metal casting installation, by means of at least a first and second elongated latches (32) pivotally mounted on a hinge (36), such that the latch can pivot from a fixing position to an idle position. The idle position of the latches allowing the engagement of the ladle shroud into its casting configuration about the collector nozzle, and the fixing position of the latches engages catching means (33, 33a) provided on said latches into matching fixing means (31, 31a) located on the gate frame holding the collector nozzle.
