Abstract:
A strand pulling-off method for a metal strip cast in a curved continuous casting plant, the method comprising pulling the metal strip initially vertically from a casting mold using a curved entry segment driven with an entry speed, imparting to the metal strip in the curved entry segment a curved shape such that the metal strip travels in a circular arc, straightening the metal strip after reaching a horizontal strip travel direction using a curved exit segment driven with an exit speed and conveying the metal strip out of the curved exit segment, guiding the metal strip between the curved entry segment and the curved exit segment initially over a reaction roller arranged at the circular arc and then over a guide roller underneath the circular arc, detecting whether the metal strip is in contact with the guide roller or the metal strip is lifted off from the guide roller, and increasing the exit speed when the metal strip is in contact with the guide roller and decreasing the exit speed when the metal strip is lifted off from the guide roller.
