Disclosed are a method and a continuous casting device for dynamically placing roller segments (13 to 17) against a cast bar (4) made of metal, particularly steel. The inventive continuous casting device comprises pairs of rollers (18) which are placed against each other in a position-controlled and pressure- controlled manner by means of piston-cylinder units (19), the hydraulic pressure being switched from position-controlled operation to pressure- controlled operation when a threshold pressure is reached. In order to extend the range of applications of the inventive method, said method is applied to roller segments (13 to 17) of continuous bloom and billet casting devices, said roller segments (13 to 17) being arranged in the cold bar zone, hot bar zone, or soft reduction zone.
La présente invention concerne un procédé et un dispositif de coulée de barre permettant un réglage dynamique de segments de rouleau (13 à 17) sur la barre de coulée (4) en métal, notamment en acier. Ce dispositif comprend des paires de rouleau (18) dont la position et la pression sont réglées au moyen d'unités piston-cylindre (19). La pression hydraulique en fonctionnement de réglage de position à réglage de pression est modifiée lorsqu'une pression seuil est atteinte. Afin d'élargir le domaine d'utilisation de ce procédé, on utilise des segments de rouleau (13 à 17) de dispositifs de coulée de barre à ébauche et à billette qui sont placés dans une zone de barre formée à froid, dans une zone de barre formée à chaud et/ou dans une zone de réduction douce.
