Coupling device for reversibly coupling ladle shroud to collector nozzle, self-supporting ladle shroud, kit for self-supporting ladle shroud, and method for coupling ladle shroud to collector nozzle

摘要

A coupling device for reversibly coupling a ladle shroud to a collector nozzle, a self-supporting ladle shroud, a self-supporting ladle shroud kit, and a method of coupling a ladle shroud to a collector nozzle. The present invention includes at least a first elongate latch and a second elongate latch that are pivotally mounted to a hinge (36) so that an inlet orifice (115a) of a ladle shroud can be pivoted from a fixed position to an idle position. According to (32), the connecting device (34) fixed to the ladle shroud (111) for reversibly connecting to the collector nozzle (112) fixed outside the bottom floor of the ladle (11) in the metal mold forming facility. About. In the idle position of the latch, the ladle shroud can be fitted into its mold forming configuration in the vicinity of the collector nozzle, and in the fixed position of the latch, the catch means (33, 33a) provided in the latch hold the collector nozzle. It is possible to fit the fitting fixing means (31, 31a) in the gate frame.
