Abstract

PURPOSE: To perform the high accurate thickness control, in case of applying the feedforward control to the automatic thickness controller of the gaugemeter system, by giving a time delay, corresponding to the traveling speed of material in the former stand, to the deviation value of the thickness on the delivery side of the former stand from the reference thickness value on the delivery side, and by applying the result to the correction of rolling reduction in the next stand.
CONSTITUTION: The draft position signal Si-1 and the rolling load signal Fi-1 are respectively produced from the draft position detector 3 and the rolling load detector 4 of the stand Fi-1 and are inputted to the thickness arithmetic unit 8. From these signals, the unit 8 operates the deviation value ΔHoi-1 of the thickness h2 on the delivery side of the stand Fi-1 from the reference thickness for the delivery side. At the same time, the Delay time (t) corresponding to the speed (v) is operated from the delivery side thickness h2, the value h1 detected by the feed side thickness detector 7, and the speed (v) detected by the speed detector 5. Next, this time (t) and the deviation value ΔHoi-1 are inputted to the thickness deviation Delay unit 11; the output of this unit 11, and the thickness deviation signal Hoi for the stand i-1 being produced from the thickness detector 10, are inputted to arithmetic unit 12 for operating the corrective amount of the rolling reduction, and hereby, the rolling reduction of the next stand (i) is corrected.
