Method and device for regulating a continuous casting machine

A method for regulating a continuous casting machine, wherein the continuous casting machine comprises a mold for forming a strand and a strand guide for guiding the strand and metal from the mold downstream of the mold;

• the method comprising:
• pouring liquid metal into the mold, via an inflow unit, wherein the liquid metal solidifies on walls of the mold, thereby forming a metal strand having a solidified strand shell and a still liquid core forming within the shell;
• drawing the metal strand out of the mold by means of rollers of the strand guide, wherein the rollers are arranged spaced apart;
• determining a measured variable correlated with cyclical variations of a casting level of liquid metal in the mold;
• processing the measured variable with incorporation of at least one computing rule and using the at least one computing rule to reduce the cyclical variations of the casting level of the liquid metal in the mold;
• and
• reducing the cyclical variations of the casting level of the liquid metal in the mold by cyclically changing the mutual spacing of opposing rollers of the strand guide toward or away from the strand before a complete solidification point, whereby the cyclical variations of the casting level of the liquid metal in the mold are opposed by anti-cyclically changing the mutual spacing of opposing rollers of the strand guide toward or away from the strand.
