摘要： There is provided a zigzagging control method for a workpiece including: an estimation step of, before rolling of a tail portion of the workpiece, acquiring at least any one of an inter-roll thrust force estimated based on an inter-roll cross angle and an inter-roll friction coefficient and a material-roll thrust force estimated based on a material-roll cross angle and a material-roll friction coefficient; and a tail control step of, during the rolling of the tail portion of the workpiece, measuring work-side and drive-side rolling loads, correcting a rolling load difference or a rolling load difference ratio based on any two of acquired parameters including a roll-axis-direction thrust counterforce at the measurement of the rolling loads, the inter-roll thrust force, and the material-roll thrust force, and performing reduction leveling control on a rolling mill based on the corrected rolling load difference or rolling load difference ratio.

摘要： The object is to provide a method of detecting a fault which ensures high-accuracy detection of a fault in piercing-rolling. A piercing-rolling mill (10) is provided with piercer rolls (1a, 1b), a piercer plug (3), a rolling load sensor (4), a thrust load sensor (5), and a control device (6). The control device (6) measures a rolling load parameter corresponding to the rolling load of the piercer rolls (1a, 1b) and a thrust load parameter corresponding to the thrust load of the piercer plug (3), and detects a fault in piercing-rolling on the basis of a measured value of the rolling load parameter and a measure value of the thrust load parameter.

摘要： For the continuous measurement of the thrust forces produced by the spinning rolls on the workpiece to be extended while the spinning rolls are rotating a measuring rod is provided, which has its one end fixed coaxially on the spindle within a hollow spindle, while its other end projects freely out of the spindle. In the plane of the free end of the measuring rod a distance sensor is arranged, which detects the radial displacement, caused by the radial flexure motion of the spindle, of the measuring rod and computes the force acting on the spinning roll using a processing unit.

摘要： There is provided a method for identifying thrust counterforce working point positions of backup rolls of a rolling mill, the method including: changing at least either friction coefficients and inter-roll cross angles between the rolls with an unchanged kiss roll load to cause thrust forces at a plurality of levels to act between the rolls, and measuring thrust counterforces in a roll-axis direction acting on rolls forming at least one of roll pairs other than a roll pair of the backup rolls and measuring backup roll counterforces acting in a vertical direction on the backup rolls at reduction support positions in a kiss roll state; and identifying, based on the measured thrust counterforces, thrust counterforce working point positions of thrust counterforces acting on the backup rolls, using first equilibrium conditional expressions relating to forces acting on the rolls and second equilibrium conditional expressions relating to moments acting on the rolls.
