Abstract
In thickness control processing, transfer processing of an entry thickness He(N) is performed (step S). In the transfer processing, data of the entry thickness He(N) is transferred from a position Pto a position Pat the same speed as the speed of a material to be rolled M. Subsequently, an amount of change in a thickness ΔH(N) is calculated (step S). The amount of the change in the thickness ΔH(N) is calculated based on data of a delivery thickness Hd(N) and data of a transferred thickness Hc(N) transferred to the position Pat a timing when the data of the delivery thickness Hd(N) is measured. Then, a target entry thickness He(N)_tgt is calculated (step S). Subsequently, a manipulated amount of rolling speed VR(N−2) and VR(N−k) are calculated (step S).
