Title: METHOD AND SYSTEM FOR CONTINUOUSLY CASTING SLABS, ESPECIALLY THIN SLABS, WITH COMPARATIVELY HIGH CASTING SPEEDS
Abstract:
The invention relates to a method and a system for continuously casting slabs, especially thin steel slabs, with comparatively high casting speeds, for example over 3m/min, in a chill (1) able to be driven in periodic oscillation. Said system comprises a strand guiding system (3) located underneath the chill (1) and having rollers (5,6) for guiding and extracting a strand (4). At least a few of these rollers (5,6) can be driven in a rotating motion either in pairs or individually. At least the driven roller (5) of at least one pair of rollers is driven by an overriding periodic oscillation (8) as well as by the rotating motion, whereby driving devices which can be electromechanically or hydraulically controlled are provided for said rollers (5,6).
