In this work, measured data from thickness gauge behind of the finishing mill stand was used for increasing accuracy of thickness control in plate rolling process. The Automatic Gauge Control (AGC) system of the mill could control roll gap for the remaining rolling passes based on the difference between measured and calculated thickness. This work was possible with some modification in software product system to use measured data without additional installation of equipment. As a result, the accuracy of thickness has been increased up to 31%. The accuracy of thickness control was defined as a standard deviation of the differences between target and measured final thickness of average.
