Abstract
PURPOSE: To improve the accuracy of the thickness, by correcting the mill elasticity through comparison between the thickness deviation detected by the thickness detector on the stand exit, and the deviation of the gaugemeter.
CONSTITUTION: The relays A and B are the relays for memorizing the roll gap, the rolling load b and the thickness deviation c, when the stand-on gaugemeter is being put on, and numbers 2, 3, 4, are memories of each relay. The thickness arithmetic unit 1 operates the thickness from the roll gap and the rolling load; the mill constant correction factor or the mill constant being stored in the unit 1 is given by the renewing unit 5 for the correction factor for range of mill constant. The unit 5 is a unit for renewing the correction factor for the range of mill constant according to the thickness deviation obtained from the reference thickness and the thickness at the moment, and the gaugemeter deviation; and the result of renewal is applied to the thickness controllers of all stands. The arithmetic unit 6, for the amount of correction for the rolling reduction, operates the amount of correction for the rolling reduction according to the thickness deviation; and the screw driver 7 drives the screw according to the result obtained by the unit 6.
