Abstract (en)
[origin: CA2337451A1] 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, wherein some rolls are drive rolls and others are idle rolls, wherein drives are provided for the drive rolls, and wherein the drive rolls are adjustable against the cast strand in order to transmit guiding forces and strand conveying forces onto the cast strand in interaction with the idle rolls, the drive rolls and the drives are controlled to a preset rotational speed such that the drive rolls have circumferential speeds identical to one another within the limits of a preset casting speed. 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.
