偏心除去装置。[Claims for Utility Model Registration] Roll eccentricity removal comprising roll eccentricity calculation means for calculating changes in roll gap due to roll eccentricity from fluctuations in the rolling load of a rolling stand, and providing the output of the roll eccentricity calculation means to an automatic sheet thickness control device. The apparatus includes a tracking means for tracking the output of a plate thickness gauge installed on the entry side of the rolling stand to the rolling stand position in synchronization with the progress of the plate, and a tracking means for tracking the output of the plate thickness gauge installed at the entry side of the rolling stand to the rolling stand position, and a tracking means for tracking the output of the plate thickness gauge installed at the entry side of the rolling stand to the rolling stand position; and a correction means for calculating an expected value of roll gap fluctuation caused by the fluctuation, and a value obtained by subtracting the output of the correction means from the output of the roll eccentricity calculation means is output to an automatic plate thickness control device. A device for removing roll eccentricity in a rolling stand.
