Abstract
PURPOSE: To prevent the overshoot at the tension control, by lowering the contribution of the integral control until the rolling mill's impact drop due to the feeding of the rolled material is recovered and the tension is settled to the specified value, at performing the titled control for the tension according to the proportional plus integral controlling method.
CONSTITUTION: The deviation signal ΔT, for the deviation of the output signal T of the detector 4 for the tension of the rolled material 3 between the i-th and (i+ 1)-th rolling mills 1, 2, from the reference tension signal T* given by the setter 5, is sent out from the subtracter 8. The contact 14 is inserted into the circuit; when the tip of the rolled material 3 is fed to the rolling mill 1 and next 2, the contacts 9, 13, are closed, and the tension control starts. At this time, since the contact 14 is left open, the tension control is performed by only the proportional controller 10. Next, at the point of time that the impact drop of the rolling mill 2, caused by feeding the rolled material's tip into the rolling mill 2, is recovered and the tension 3 is settled to the suitable value, the contact 14 is closed. Hereafter, the integral controller 11 is actuated for performing the tension control according to the proportional plus integral controlling method.
