| 摘 要： | 在分析各种平直度预设定控制算法优缺点的基础上,提出一种基于板厚标准曲线的平直度预设定控制算法。首先,建立了基于分步优化的平直度和板厚标准曲线制定方法,该方法将平直度判别和平直度预报分开独立计算,通过分步优化得到平直度标准曲线和板厚标准曲线,计算快速、稳定。其次,采用横断面预报模型优化计算平直度预设定值,使计算的带钢出口厚度横向分布逼近板厚标准曲线,得到基于板厚标准曲线的平直度预设定控制方法,该方法计算快速、稳定,完成一次在线设定计算时间约为1.781 s,满足工业在线应用实时性的要求。最后,以某1 800 mm五机架冷连轧机为例验证了上述算法的计算精度,满足工程需要。

| Abstract: | The flatness pre-set control method based on the thickness standard curve is proposed,which is based on the analysis of various flatness pre-set control methods.First of all,the established method of the flatness standard curve and the thickness standard curve based on stepwise optimization is founded,and by calculating the flatness discrimination and the flatness forecast separately,the flatness standard curve and the thickness standard curve are attained with stepwise optimization,the calculation speed is... |
