Abstract
A method and device are provided for casting a strand of liquid metal which is cast into a mold, and which is drawn as a strand out of the mold. The casting level, e.g., a level of the liquid metal in the mold, is regulated to a predetermined casting-level desired value using a casting-level controller having at least one integrator. The output of the integrator of the casting-level controller is replaced by a predetermined value when the difference between the casting-level actual value and the casting-level desired value exceeds a tolerance threshold.
