METHOD AND DEVICE FOR DYNAMICALLY RESTING ROLLER SEGMENTS THAT SUPPORT AND/OR GUIDE BOTH SIDES OF A CAST BAR MADE OF METAL, PARTICULARLY STEEL

摘要

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.
