Research on digital twin of flatness control system for cold rolled copper strip
Based on the physical system for flatness control of cold-rolled copper strip,the collaborative modeling method of mechanism analysis and data intelligence was adopted,and online sensing,Internet,cloud services,big data,virtual simulation,machine learning and other technologies were applied to develop a set of digital twin system of cold rolled copper strip flatness control,which realizes real-time interaction with the physical system and forms an information physical system oriented to flatness control.The industrial application in 600 mm four-high rolling mill and 600 mm six-high rolling mill was realized.The results shows that the digital twin system for cold rolled copper strip can not only improve the level and quality of the flatness control by real-time monitoring and optimizing the rolling process,but also provide early warnings of rolling faults to enhance the operation stability and safety of rolling mill.This paper provides new ideas,methods and application scenarios for developing a next-generation of intelligent flatness control technology of cold rolled strips.
