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.
Method for the dynamic adjustment of roller segments (13 to 17) that support and/or guide both sides of a continuously cast strand (4) made of metal, especially steel, with at least two successive pairs of rollers (18), which are adjusted relative to each other by piston-cylinder units (19), which are acted upon with both position control and pressure control, and the pairs of rollers (18) are then adjusted to the continuously cast strand (4) by position control, and the hydraulic pressure is switched from position-controlled operation to pressure-controlled operation when the hydraulic pressure in a piston-cylinder unit (19) reaches a predetermined value, comprising the application of the method to roller segments (13 to 17) of continuous bloom and billet casting machines (20), such that the roller segments (13 to 17) are installed in the cold bar zone, the hot bar zone, and/or the soft reduction zone and are operated by an automatic segment control system (32) and a basic automation system (33).
Continuous casting device for casting continuous bloom or billet sections, with a containment roll stand (5), which is arranged after the continuous casting mold (2), and with a bending-straightening unit (11), wherein a device is arranged at least partially in front of the bending-straightening unit (11) or completely behind the bending-straightening unit (11), with several hydraulically operated piston-cylinder units (19) with position-controlled or pressure-controlled, adjustable roller segments (13 to 17), each of which has at least one driven roller (23).
