The invention relates to a device for the continuous casting of metal that consists of a lifting platform (3a, 3b) that is driven by a drive aggregate (4a, 4b) so as to oscillate, and that further comprises a die for continuous casting that is received by the lifting platform and a stationary supporting structure (2a, 2b) that is provided with guide elements for receiving the lifting platform. The aim of the invention is to improve the guide elements of the supporting structure. To this end, the guide elements are configured as an elastic spring system (61a to 64a, 61b to 64b). Said spring system consists of two spring legs (201, 202; 301, 302) that are at angles with respect to each other and that extend in a direction perpendicular to the direction of oscillation. The two spring legs are bifurcated and the overlapping upper and lower ends (211a, 211b, 212a, 212b; 311a, 311b, 312a, 312b) of the two spring legs represent the support surface for the elevated platform (3a, 3b) or the connecting surface with the stationary supporting structure (2a, 2b). The spring system, in addition to the force in the direction of oscillation, also compensates interfering forces in the direction perpendicular to the direction of oscillation in order to establish a load balance.
L'invention concerne une unité pour réaliser la coulée continue de métal, constituée d'une table élévatrice (3a, 3b), pouvant être entraînée de manière oscillante au moyen d'une unité d'entraînement (4a, 4b), ainsi que d'une coquille de coulée continue logée dans la table élévatrice, et d'une armature de support (2a, 2b) pourvue d'éléments de guidage servant à recevoir la table élévatrice. L'invention vise à améliorer ces éléments de guidage. A cet effet, ces derniers se présentent sous la forme d'un système de ressorts élastique (61a à 64a, 61b à 64b) composé de deux branches de ressort (201, 202; 301, 302) qui sont placées de manière à former un angle l'une par rapport à l'autre et s'étendent perpendiculairement au sens d'oscillation. Ces deux branches de ressort sont conçues de manière à présenter la forme d'un diapason. Les extrémités supérieures et inférieures (211a, 211b, 212a, 212b; 311a, 311b, 312a, 312b), se chevauchant respectivement, des deux branches de ressort forment la surface d'appui de la table élévatrice (3a, 3b,) ou la surface de raccordement avec l'armature de support (2a, 2b). Ce système de ressorts compense, outre la force exercée dans le sens d'oscillation, les forces perturbatrices dans des directions perpendiculaires au sens d'oscillation, par des répartitions de charge.
