Disclosed is a control and/or regulation device for an elevating platform (10) of a continuous casting machine (1) for liquid metals, especially liquid steel material (3), said platform (10) supporting a continuous casting die (5). The inventive control and/or regulation device comprises an oscillating drive mechanism (11) which is composed of several stationary piston-cylinder units (12) that are hingedly connected to the elevating platform (10). The control and/or regulation device further comprises surveying units (16) which are located on the hydraulic cylinder (12a) and whose signals are directed to the control and/or regulation stand (25) and back into the associated actuators via electrical connections. In order to be able to operate the disclosed control and/or regulation device in a decentralized manner while keeping the wiring effort low in spite of the large number of electrical connections (21), the electrical connections (21) are run as wire stacks (23) on one respective shaft regulator (31) in the vicinity (30) of the elevating platform (10), said shaft regulator (31) being connected, via a field bus (22), to a stored- program controller (32) that is located at a distance in the control and/or regulation stand (25).
L'invention concerne un dispositif de commande et/ou de régulation destiné à une table élévatrice (10) d'un dispositif de coulée continue (1) de métaux liquides, notamment d'acier liquide (3), portant une coquille de coulée continue (5), comportant un entraînement d'oscillation (11) composé de plusieurs unités piston-cylindre (12) articulées de façon fixe et sur la table élévatrice (10), pourvues d'appareils de mesure de terrain (16) sur le cylindre hydraulique (12a), dont les signaux sont transmis par l'intermédiaire de connexions électriques vers la station de commande et/ou de régulation (25), puis vers les actionneurs correspondants. Un tel dispositif de commande et/ou de régulation est employé de façon décentralisée et nécessite un câblage réduit malgré le grand nombre de connexions électriques (21), du fait que les connexions électriques (21) sont guidées, à proximité (30) de la table élévatrice, en tant que paquets de câbles (23) le long d'un régulateur d'axe (31) connecté par l'intermédiaire d'un bus de terrain (22) à une commande à mémoire programmable (32) située à distance dans la station de commande et/ou de régulation (25).
