宝钢五冷轧连退CVC中间辊窜动控制系统

摘要

The CVC intermediate roller shifting control system for Cai5 skin pass mill in Baosteel is introduced, the mechanical equipment, system configuration and control principle of the system are described. By adopting position feedback closed-loop control, and synchronous control for the upper and lower rollers, the accuracy of the control system and the synchronization of the upper and lower rollers are enhanced. The practical production indicates that the position control accuracy and the position deviation control accuracy for the rollers all reach ± 1 mm; the system features high control accuracy and good performance of synchronous control, it provides excellent foundation to automatic shape control.%介绍了宝钢五冷轧连退机组平整机部分中间辊窜动控制系统,说明了系统的机械设备、系统配置和系统的控制原理.系统采用位置反馈闭环控制和上、下辊同步控制,提高了中间辊窜动控制系统的控制精度和上、下辊同步性.实际生产表明,该控制系统的位置控制精度和上、下辊位置偏差控制精度均达±1 mm,具有控制精度高、同步控制性能好等特点,为机组的自动板形控制打下了良好基础.
