基于板厚标准曲线的平直度预设定控制方法
Flatness pre-set control method based on thickness standard curve
摘要
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 thiclmess standard curve are attained with stepwise optimization, the calculation speed is fast and the calculation stability is good.Secondly, the flatness pre-set values are optimized with the strip cross section forecast model, making the transverse distribution of the exit thickness of the strip calculated approach the thickness standard curve, and then the flatness pre-set control method based on the thiclmess standard curve is gained.The time of completing once on-line preset calculation is about 1.781 s and the method can satisfy the real-time need of the engineering on-line application with fast calculation speed and good calculation stability.Finally, the calculation precision of the flatness pre-set control method based on the thiclmess standard curve is verified on some 1 800 mm five-stand cold strip tandem mill for example, and the calculation precision can satisfy the need of the engineering on-line application.关键词
