一种成品盘卷防挤压变形的控制系统及方法

A control system and method for preventing extrusion deformation of finished coil

轧钢厂双高线打包机的打包过程对于双高线的生产非常重要。随着钢坯截面积及重量的调整,以及打包过程中相关执行组件的变量波动,出现了由于动作匹配不佳而导致的盘卷与打包机相关动作组件的异常挤压,导致盘卷有擦伤,严重影响成品质量。文章通过对盘卷在打包机打包时盘卷和升降台的2次分步骤动作的行程及速度匹配等相关控制系统进行研究、实验、数据化分析,研究出基于速度匹配以及位移匹配的量化差异性以及整个系统动作过程的斜率输出及闭环反馈差异性,再结合实际运行情况对系统进行逐步优化,并对盘卷质量变化进行调整,实现了盘卷在打包机打包时盘卷和升降台的2次分步骤动作的行程及速度匹配的最优。

The packing process of the packing machine of the double-high wire rod in the rolling mill is very important for the production of the double-high wire rod.With the adjustment of the sectional area and weight of the billet,and the fluctuation of the variables of the relevant execution components during the packaging process,the abnormal extrusion of the coil and the relevant action components of the packer caused by the poor matching of the actions occurred,which caused the coil to be scratched and seriously affected the quality of the finished product.Through the research,experiment and data analysis of the relevant control systems such as the travel and speed matching of the two step actions of the coil and the lifting table when the coil is packed in the packer,the quantitative differences based on the speed matching and displacement matching,as well as the slope output and closed-loop feedback differences of the whole system operation process,are studied,and the system is gradually optimized in combination with the actual operation conditions,and the coil quality changes are adjusted,it realizes the optimal matching of the travel and speed of the coil and the lifting table in two steps when the coil is packed in the packer.
