Abstract

PURPOSE:To prevent overfill by detecting beforehand the magnitude and direction of the thrust force acting on work rolls, predicting the generation of overfill and adjusting right and left drafts and right and left rolling benders in accordance with the detected values after the trailing end of a material to be rolled passes through the previous rolling stand. CONSTITUTION:Tension is applied on a rolling material 1 and the direction and magnitude of the thrust force acting on work rolls 6 under rolling are detected with a thrust force detector 7 in rolling with a hot strip mill. The detected thrust force is added in an adder 10, and is inputted to an arithmetic device 11. On the other hand, when the trailing end of the material 1 passes through the previous rolling stand 2, the rolling load of a rolling load detector 8 is inputted to a detector 13, the detection signal whereof is inputted to an arithmetic device 11. At the same time, a control device 14 operates a screw down device 13 to adjust the right and left drafts and right and left roll benders of the stand 2.
