Abstract

PURPOSE:To high accurately control the thickness of rolled sheet, by comparing while performing the rolling work the gaugemeter thickness at an arbitrary point with actually measured thickness at the same position in the longitudinal direction, and by correcting the offset term of the gaugemeter formula correspondingly to the deviation obtained from above-mentioned comparison. CONSTITUTION:When the tip of the rolled material 10 delivered from the rolling mill 12 arrives at the position of the rolled material detector 36, the detector 36 produces an output signal to the gaugemeter thickness arithmetic unit 42 which then operates the gaugemeter thickness Ha from the screw position S detected by the screw position detector 30, the rolling load F detected by the load cell 32, and the roll's r.p.m. deteced by the roll's r.p.m. measuring device 40. When the tip of the material 10 arrives at the position of the rolled material detector 38, the actually measured thickness reader 44 reads the output Hb of the thickness meter 34 at this point of arrival. The deviation arithmetic unit 46 operates the deviation of thickness Ha from actually measured thickness Hb, and the rolling reduction's set point arithmetic unit 48 operates the optimum value of the offset term of the gaugemeter formula from this deviation and operates the rolling reduction's set point S0; this set point S0 is inputted to the screw position controller 50 which then controls the screw 16.
