Abstract
In a method for casting prefabricated products in a continuous casting device, having a casting mold and a strand guide downstream of the casting mold, wherein the strand guide has rolls positioned opposite one another in pairs for supporting and guiding the solidifying cast strand. The motor torques of the drives are maintained at a level as equal as possible below a permissible torque limit value relative to a loadability of the strand shell. For a single drive and corresponding drive roll the permissible torque limit value is measured by continuously increasing the drive torque starting at zero and monitoring the rotational speed of the drive roll, while the remaining drive rolls are controlled to a preset nominal casting speed. For a superproportional increase of the rotational speed, the torque limit value is determined and the process is stopped.
