Abstract

An adjustment device for adjusting the position of at least one strand supporting element (5) relative to a supporting stand (9, 10) carrying at least one further strand supporting element (6), of a strand guide in a continuous casting plant comprises at least one hydraulic adjustment cylinder (12) contacting a strand supporting element (5) directly or indirectly on the one side and the supporting stand (9, 10) carrying a further strand supporting element (6) on the other side, the movement of the strand supporting element (5) being detectable via a position sensor (17) and controllable by means of an automatic controller (26). In order to safely attain the high precision in positioning the strand supporting elements (5, 6) sought for a strand guide at yet a minimum expenditure and a minimum susceptibility to failure, at least one directional control valve (21A, 21B) capable of being switched via a three-level controller (26) is provided for actuating the hydraulic adjustment cylinder (12) FIG. 2.
