Abstract

PURPOSE: To surely prevent the transverse bend of the rolled material, by giving a force to the rolled material on the delivery side of the rolling stand so as to advance perpendicularly to the roll axis, and by utilizing the hereby generated difference of flatnesses between both ends of rolled material, in controlling the rolling mill.
CONSTITUTION: A couple of side guides 18, 20, being arranged at both sides on the delivery side of the rolling stand 10, gives an external force to the rolled material 8 so as to advance perpendicularly to the axis of the rolling roll 16. The detectors 22, 24, detect the flatness generated by this external force between lateral both ends of the rolled material 8. The difference of these two detecting outputs is operated by the operator 26; and correspondingly to this output of the operator 26, the driving side screw 12 and the driven side screw 14 are controlled by the driving side draft position corrector 28 and the driven side draft position corrector 30. According to this method, the transverse bend of the rolled material 8 on the delivery side of the rolling stand 10 is eliminated.
