A continuous rolling mill including roll stands arranged in series, each of which has a pair of work rolls and roll chocks for supporting them respectively. One of the roll chocks is mounted on the frame of the roll stand to be movable in a direction parallel to the direction of path of the workpiece. A load sensing rod is provided to contact at its one end with the roll chock and to be thrusted through the roll chock by tensile or compression force occurring when the workpiece is being captured by the pair of rolls. The load sensing rod is hydraulically supported under a predetermined pressure so that the rod is shifted under an excessive load. The movement of the sensing rod is transduced to an electric signal representing the force for control of the mill.
