Abstract

PURPOSE:To obtain the sheet gauge in desired accuracy, by caluculating the sheet gauge deviation from the measurement of the temperature of the rolled material before and after rolling work, and by correcting the draft position. CONSTITUTION:The temperature of the sampled material, measured by the thermometer 1 is inputted to the delay circuit 3. The delayed temperature is sent to the material temperature arithmetic unit 4. Then, the material temperature theta in the rolling mill is calculated by the arithmetic according to the formula I, and its deviation DELTAtheta from the set temperature thetas is calculated, accordingly, the sheet gauge deviation DELTAh on the run-out side is calculated according to the formula II. Further, the draft position correction value DELTASo is operated according to the formula III. Accordingly, the draft position correction value DELTASo is added to the draft position (roll gap) set value So,s by the adder 7, and the reference draft position So', a is obtained. This reference draft position So', a is added to the draft position correction value So,xray by the adder 11 and the new reference draft position So, a is obtained. The draft position control unit 14 is calculated the draft position adjustment using the deviation of the reference draft position So, a from the draft position feedback signal So, and drives the screw down device.
