<p>PURPOSE:To minimize a controller and to control the sheet thickness at the tail end of a rolling stock by controlling the rolling reduction of stands at the time of the rolling to be next executed in accordance with the learning value calculated from the thickness deviation value measured by a thickness gage provided on the outlet side of the final stand. CONSTITUTION:The detection signal of the thickness deviation outputted from the thickness gage 4 provided on the outlet side of the final stand S7 is inputted to a sampling learning device 5. The correction value of rolling down conditions corresponding to conditions is calculated in accordance with the inclination of the determined thickness deviation in the learning device 5. The rolling reductions of the respective stands at the time of the ensuing rolling are corrected and controlled in accordance with the results of the respectively previous stands by using the above-mentioned results. The thickness control at the tail end is executed with good accuracy by the above-mentioned method.</p> |
