摘    要：目前国内热连轧机板形控制系统自主集成的很少,而平坦度反馈控制是热连轧板形控制系统的一个重要组成部分。针对济南钢铁股份有限公司1700ASP(Angang Strip Production)热连轧机组,根据热连轧机板形控制理论,确定了平坦度反馈控制策略。在此基础上,建立了基于PID控制器的热连轧平坦度反馈控制模型,进行了在线编程、调试和投入工作。自平坦度反馈控制系统投入运行以来,运行稳定,生产数据统计表明,平坦度控制精度得到很大提高。

Abstract: Flatness feedback control is an important portion of the automatic shape control required for hot tandem rolling.Up to now,however,only a few shape control systems have been reportedly of domestic independently integrated.Dedicated to Jinan Iron and Steel Co.,Ltd.1 700 mm ASP rolling mill,a flatness feedback control strategy is proposed according to the shape control theory of hot tandem mill.To implement the strategy,the flatness feedback control model with PID controller is built,and subsequentially,on-line programming,debugging and testing are proceeded.The statistical data from practice shows that the flatness of the strip products has been substantially improved since the flatness feedback control system was put into operation.
