To provide a loop amount control device which correctly calculates a loop amount in a continuous rolling plant for a wire material, steel bar and the like to improve the control accuracy.SOLUTION: A loop amount control device according to an embodiment calculates a correction value of the speed reference on the basis of a loop amount of a rolled material conveyed between two rolling machines and supplies the correction value to a rolling main control system that generates the speed reference of the two rolling machines. The loop amount control device comprises a calculation unit which calculates the loop amount on the basis of the first image data acquired by imaging the rolled material conveyed between the two rolling machines by a first camera having an optical axis in parallel to the first direction intersecting the conveyance direction of the rolled material and the second image data acquired by imaging the rolled material conveyed between the two rolling machines by a second camera having an optical axis in parallel to the second direction intersecting the conveyance direction and the first direction.SELECTED DRAWING: Figure 1 【課題】線材や棒鋼等の連続圧延プラントにおけるループ量を正確に計算して、制御精度を向上させたループ量制御装置を提供する。【解決手段】実施形態に係るループ量制御装置は、２台の圧延機の速度基準を生成する圧延主幹制御システムに、前記２台の圧延機の間で搬送される圧延材のループ量にもとづいて前記速度基準の補正値を計算して前記圧延主幹制御システムに供給する。このループ量制御装置は、前記圧延材の搬送方向に交差する第１方向に平行な光学軸を有する第１カメラによって、前記２台の圧延機の間で搬送される前記圧延材を撮影して取得された第１画像データおよび前記搬送方向および前記第１方向に交差する第２方向に平行な光学軸を有する第２カメラによって、前記２台の圧延機の間で搬送される前記圧延材を撮影して取得された第２画像データにもとづいて、前記ループ量を計算する演算部を備える。【選択図】図１
