Abstract: In a plate thickness control process, first, a transfer process of an inlet-side plate thickness He(N) is performed (step S1). In the transfer process, data on the inlet-side plate thickness He(N) measured by a plate thickness gauge 11 is transferred at the same speed as the speed of a to-be-rolled material M from a position P11 (the installation location of the inlet-side plate thickness gauge 11) to a position P12 (the installation location of an outlet-side plate thickness gauge 12). Subsequently, a plate thickness change amount ΔH(N) is calculated (step S2). The plate thickness change amount ΔH(N) is calculated on the basis of data on the outlet-side plate thickness Hd(N) and data on the transferred plate thickness Hc(N) transferred to the position P12 at a timing when the data on the outlet-side plate thickness Hd(N) is measured. Subsequently, an inlet-side target plate thickness He(N)_tgt is calculated (step S3). The inlet-side target plate thickness He(N)_tgt is calculated on the basis of the data on the plate thickness change amount ΔH(N) and data on an outlet-side target plate thickness Hd(N)_tgt. Subsequently, the operation amounts for roll speeds VR(N-2) and VR(Nk) are calculated (step S4).
