ABSTRACT:
In a method for vertical continuous casting of a steel band, a strand (11) of a parallelogram-like cross section is cast at first in a revolving chill-mold (2) and is thereafter transferred from said initial cross section with completely solidified longitudinal edges (10) and liquid core into a band (1) with plane-parallel cross section, this occurring in such a way that an already solidified shell (9) of the strand (11) which becomes increasingly thicker by cooling is increasingly compressed in the casting direction in a forming device (4) without upsetting deformation of the completely solidified longitudinal edges (10). In order to provide advantageous conditions it is proposed that after the compression into a band (1) the strand (11) with a still liquid core (16) is guided during the complete solidification of the core merely in a forming gap with a constant width corresponding to the thickness of the completely solidified longitudinal edges (10) and is calibrated in this process.
