Method and casting/rolling system for casting and rolling a continuous strand material

A method for operating a casting/rolling system for casting and rolling a continuous strand material, wherein the casting/rolling system comprises:

• a strand casting machine and a rolling line arranged downstream of a strand casting machine,
• wherein the strand casting machine is provided with a chill-mold;
• wherein the rolling line is provided with n roller frames, wherein n=1 through N, provided with respective drivers for the rollers, a pass sequence plan model and a drive controller for controlling the drives of the rollers;
• and
• wherein the method comprises the following steps:
• controlling the drives for the rollers of the first roller frame by a drive controller in response to a target value specification of the pass sequence plan model;
• wherein the strand casting machine is further provided with at least one strand guide arranged downstream of the chill-mold with strand guide rollers and at least one drive for driving at least one of the strand guider rollers, a strand casting machine drive model and a strand guide roller drive controller, wherein the control over the drive of the at least one strand guide roller is performed via the strand guide roller drive controller in response to a target value specification of the strand casting machine drive model;
• wherein the pass sequence model presets as a target value specification a target rotational speed for the drive of the first roller frame of the rolling line;
• and
• the strand casting machine drive model sets as a target specification a target torque for the drive of the at least one driven strand guide roller.
