The invention relates to a device and a method for supporting and guiding a cast strand in a strand guiding device (100) after leaving a continuous casting mould. The strand guiding device (100) comprises at least one segment, which has a first roller bridge (114-1) on one wide side of the cast strand and a second roller bridge (114-2) on the opposite wide side of the cast strand, wherein at least one roller is rotatably mounted respectively on the first and second roller bridges to support and guide the cast strand. To allow the guidance of the strand and the strand to be made more flexible, it is proposed according to the invention to provide at least a first setting element (118-3) for connecting the first roller bridge (114-1) to a first fixed land and for individually positioning the first roller bridge with respect to the neutral phase (N) of the cast strand, and at least a second setting element (118-2) for connecting the second roller bridge (114-2) to a second fixed land and for individually positioning the second roller bridge with respect to the neutral phase (N) of the cast strand.

L'invention concerne un dispositif et un procédé de soutien et de guidage d'une barre de coulée dans un dispositif (100) de guidage de barre après que la barre a quitté une lingotière de coulée continue. Le dispositif (100) de guidage de barre comprend au moins un segment qui présente un premier pont de rouleaux (114-1) sur un des côtés larges de la barre de coulée et un deuxième pont de rouleaux (114-2) sur le côté large opposé. Au moins un rouleau respectif est monté à rotation sur le premier et le deuxième pont de rouleaux pour soutenir et guider la barre de coulée. Pour rendre plus souple le guidage de barre et la barre, il est prévu selon l'invention de prévoir au moins un premier élément d'ajustement (118-3) qui relie le premier pont de rouleaux (114-1) à un premier méplat fixe et qui positionne individuellement le premier pont de rouleaux par rapport à la phase neutre (N) de la barre de coulée et au moins un deuxième élément d'ajustement (118-2) qui relie le deuxième pont de rouleaux (114-2) à un deuxième méplat fixe et qui positionne individuellement le deuxième pont de rouleaux par rapport à la phase neutre (N) de la barre de coulée.
