摘要
武钢防城港冷轧厂2030高速连退线自2015年开始安装调试以来,由于高速连退线在机组运行过程中速度高、节奏快、控制精度精确,对带尾的剪切要求也非常高,并要求实现无人工干预的全自动剪切,但由于剪切废料导板的长度以及剪切夹送辊前后距离的限制,对带尾废料长度要求精度非常高,超出精度范围就会造成卡钢,生产线顺控无法进行从而造成停机影响生产。通过对带尾剪切长度的优化,根据机械固有长度建立数学模型,实现对带尾剪切速度的控制来优化带尾剪切、精确控制剪切长度,解决了因带尾剪切长度不准停机的故障,实现高速连续自动化生产。
Since the 2030 high speed continuous annealing line in Fangchenggang cold rolling mill of Wuhan Iron and steel company has been installed and debugged since 2015, the high speed continuous retreating line has high speed, fast rhythm and precise control precision. The demand for cutting with tail is also very high, and requires the realization of automatic cutting without manual intervention, but due to the length of the shearing waste guide plate. As well as the limit of the distance between the front and back of the clipping roller, the precision of the length of the tail waste is very high. Through the optimization of the length of the tail shear, the mathematical model is established according to the inherent length of the machine. The control of the shear speed of the belt is realized to optimize the shear length of the belt tail and to control the shearing length accurately.
