To provide a control device that prevents deterioration in yield when a flying setting is changed twice.SOLUTION: A control device 20 for controlling a tandem rolling mill and rolling a rolled material includes: a setting determination part 21b for determining a setting related to a flying setting change in the case of implementing flying setting change twice; and a setting output part 21c for outputting information of a setting related to a flying setting change to N units of rolling mills. Settings related to a flying setting change include: a setting in which a flying change start point inter-distance that is a distance of a rolled material before rolling between a first flying change start point when the first flying setting change is started, and a second flying change start point when a second flying setting change is started, is set to a distance at which the first flying setting change and the second flying setting change are not executed at the same timing in the same rolling machine; a setting in which a first rolling mill is set as a pivot rolling mill regarding a change in roll speed at the first flying setting change; and a setting in which the Nth rolling mill is set as a pivot rolling mill regarding a change in roll speed at the second flying setting change.SELECTED DRAWING: Figure 2 【課題】走間設定変更を２回行う場合に歩留まりの悪化を防止する制御装置を提供する。【解決手段】タンデム圧延機を制御して圧延材を圧延する制御装置２０であって、走間設定変更を２回実施する場合の走間設定変更に関する設定を決定する設定決定部２１ｂと、走間設定変更に関する設定の情報をＮ台の圧延機に出力する設定出力部２１ｃとを備え、走間設定変更に関する設定には、１回目の走間設定変更を開始する第１走変開始点と２回目の走間設定変更を開始する第２走変開始点との間の圧延前の圧延材の距離である走変開始点間距離を、１回目の走間設定変更と２回目の走間設定変更が同一の圧延機において同一のタイミングで実施されない距離にする設定が含まれ、１回目の走間設定変更でのロール速度の変更に関し第１圧延機をピボット圧延機とする設定が含まれ、２回目の走間設定変更でのロール速度の変更に関し第Ｎ圧延機をピボット圧延機とする設定が含まれる。【選択図】図２
