Zusammenfassung:In continuous casting in a continuous casting plant, a strand (2) after emergence from the mold (1) is reduced in thickness by a wedge-shaped roller gap. In order to assure upon the casting to obtain the shortest possible wedge-shaped solidified head piece (25) or in the event of an interruption in casting or a decrease in the operating casting speed a short completely solidified strand intermediate piece of a thickness (28) differing from the desired final thickness (26) of the strand, the strand (2) is reduced in thickness exclusively in a region in which it has a liquid center (20), support segments (4, 5) being so directed at all times that the liquid tip (19) of the liquid center (20) always lies in a region of the strand guide in which the roller gap developed by the rollers (8) is the narrowest parallel gap-with respect to the following strand guide and disregarding a roller adjustment which follows the shrinkage of the completely solidified strand.
