液压轧机厚度自动控制的设计

随着轧制理论的不断深入研究 ,自动检测与控制技术不断发展 ,特别是高性能电液伺服伐在轧钢工业上的应用 ,在机械、液压、电气及自动控制的密切配合下 ,使液压轧机的发展达到了一个新的水平。而液压 AGC(厚度自动控制 )是液压轧机的核心部分 ,它关系到液压轧机的产品精度和轧机的自动化水平。介绍了采用预控的方法来消除入口带材厚度对出口厚度的干扰 ,以及利用监控的方法来准确锁定成品尺寸。

Design of Automatic Gauge Control of Hydraulic Mill

With the study in a deepgoing way for roll theory,increasing development of automatic test and control technology,and especially the application of high performance electrohydraulic servo in steel rolling industry,development of hydraulic rolling mill has reached to a new level in a combination of mechanical,hydraulic,electronic and automatic control technology,Automatic gauge control(AGC) is a kernel part in hydraulic mill,and presents the product accuracy of hydraulic mill and automatic level of the hydraulic mill.The paper has introduced the elimination of thickness interference of in band to out band with procontrol method,and accurately locking the finished product dimension through the monitor way.
