Abstract
PURPOSE:To control the width of a rolled strip to uniform width in the stage of rolling the strip with tandem rolling mills by forecasting the width fluctuations from the fluctuations in the tension on the outlet side of rolling stands and correcting the inlet side tension of the rolling stand in accordance with said width fluctuations. CONSTITUTION:A tension controller 24 having a looper 28 is provided between the final stand 12n for rolling of a strip 10 and a stand 12n-1 before final stand, and the torque of the looper 28 is so controlled with a driving motor 30 that the tension of the strip 10 is kept constant. The tension of the strip 10 between the rolling stand 12n and a take-up roll 22 is detected with a detector 38, the output thereof is inputted to a width fluctuation forecasting operator 40 and is further inputted to a tension correction quantity operator 42, so that the correction quantity of the tension between the rolls 16n-1 and 16n necessary for eliminating the flutuations in the width is calculated. This signal is inputted via a distributor 44 to a tension controller 34 which is turn corrects the inlet side tension of the rolling roll 16n, thereby controlling the width of the strip 10 out from the final stand 12n to the uniform value.
