Abstract (en)
[origin: EP0068814A1] The apparatus has a low height, a curved mold (6), and a multi-point straightening zone (10). The prior art involves a problem in that the straightening rolls (7) are not reliable due to a high load which is generated during a non-stationary casting period during which the top or bottom section of a strand (3) is conveyed through a multi-point straightening zone (10). One selected pair of straightening rolls (11) is shunted from the defined radius (Rn) of the curve by means of cone-shaped springs (28) or hydraulic cylinders so that the distance between the two pairs of straightening rolls (11) which are engaged in straightening during a non-stationary casting period is increased. The reliability of the straightening rolls (11) is so enhanced that high-speed and moderate-cooling casting in a low-head CCM can be directly combined with hot-rolling of the strands (3).
