摘要： Controlling the roll diameter distribution across the axial direction of a rolling mill roll. A device to measure or predict the roll diameter of each section, control position by control position, into which the roll is divided in the axial direction. A temperature management device, provided at every section into which the roll is divided, and includes a cooling device that cools the corresponding section or heating device that heats the corresponding section. A roll profile control device control the temperature management device so that the respective measured or predicted roll diameters follow desired values at every section into which the roll is divided.

摘要： A looper control system has a looper that is interposed between two rolling stands of a tandem rolling mill and is actuated by a hydraulic actuator; and a control calculating section for calculating a speed change rate command value of a primary rolling machine and a pressure command value of a hydraulic looper actuator so that an interstand tension and a looper height can be both controlled at target tension and looper height values, respectively, on the basis of a detected looper height value and a previously determined control gain. A resonance frequency changing section detects hydraulic flow rate of the hydraulic actuator and multiplies it by a gain to obtain a first speed change rate command value; and a damping constant changing section detects pressure in the hydraulic actuator and multiplies it by another gain to obtain a second speed change rate command value. The first and second speed change rate command values are added to a speed command value, and the total is set to the primary rolling machine speed controller.
