Equipment automation; automated thickness control system, full hydraulic pressure on. With full-stroke second flow control, constant roll gap control, constant rolling force control, deviation control, automatic pre-pressure leaning control, thickness pre-control AGC, thickness monitoring AGC, tension/speed AGC, acceleration and deceleration AGC compensation control, roll eccentricity compensation control function, rolling process database, data display and operation control, product quality tracking function, high-speed rolling data collection, automatic report generation, fault Alarm and record, remote system maintenance and other process management functions. At the same time, it realizes the control of rolling line speed control equipment and process (speed, torque and tension). It has the means to control the deviation adjustment, positive/negative bending of work rolls and positive bending of intermediate rolls; and the means to control the shape of plates such as intermediate roll traverse setting, locking, and sectional cooling of rolls.
