    Abstract: In a device for controlling a plug (5) of a metallurgical vessel (1), in particular a distributing launder of a continuous casting installation, with a plug (5), which can be raised and lowered and which is supported in a support frame which is movable relative to the metallurgical vessel (1), the support frame for the plug (5), which can be raised and lowered, is supported outside of the metallurgical vessel (1) displaceable in a direction crosswise to the lifting direction of the plug (5) and can be releasably locked together with the metallurgical vessel. By means of this a simple separation of the plug mechanism (9) and the metallurgical vessel (1) is possible without operational elaboration and an exchange of the metallurgical vessel (1), for example, is made possible without having to dismantle the entire plug mechanism (5, 9).
