Abstract
A method and a device for regulating a continuous casting system. The continuous casting system has a mold (1) and a strand guide (8) which is arranged downstream of the mold (1). Molten metal (3) is cast into the mold (1), in particular via an inlet device (4). The molten metal hardens on walls (1a) of the mold (1), such that a metal strand (7) with a hardened strand shell (5) and a still liquid core (6) is formed. The metal strand (7) is drawn out of the mold (1) by mutually spaced rollers (8b) of the strand guide (8), and a measurement variable is ascertained which correlates to the undulation of the casting level formed in the mold. The measurement variable is processed using at least one computing specification and is used to reduce the undulation of the casting level. In order to reduce the undulations of the casting level, the mutual spacing of opposing rollers (8b) of the strand guide is changed cyclically prior to the full hardening point (D).
