1150mm可逆冷轧机液压自动控制系统

Automatic Control System of 1 150 mm Reversible Cold Rolling Mill

介绍1150mm单机架冷轧机自动控制系统的硬件配置、软件配置和传感器配置,说明液压自动控制系统的位置闭环控制原理和压力闭环控制原理,重点阐述厚度控制系统中的前馈AGC、监控AGC、流量AGC和加减速厚度补偿。现场实际应用表明:成品相对厚度精度优于±1%,超差长度大大缩短,满足了实际生产的要求。

Hardware, software and sensor configuration of automatic control system for 1150 mm single stand cold rolling mill were introduced. Principles of position close loop control and rolling force close loop control in automation control system of rolling mill were explained. Feed forward AGC, monitoring AGC, mass flow AGC and gauge compensation during acceleration and deceleration in gauge control system were described in detail. Practical application shows that relative thickness accuracy of products is within ± 1%, the ultra-poor length is shortened greatly and it meets the need of practical production.
