Dynamic Decoupling for Combined Shape and Gauge Control System in Wide Strip Rolling Process 总被引:1,自引:0,他引:1
The precision of profile and thickness is the most important target for wide strip rolling,but the coupling of profile control and thickness control is ignored in rolling schedule,which holds down the simultaneous quality improvement of profile and thickness.A cross-coupled process control model for combined shape and gauge control was developed on the basis of the fact that both controls for profile and thickness are realized by controlling the rolling gap.A dynamic decoupling controller was then proposed to decouple the model.Both the simulation results and the online production data are valid and ensure the quality of the decoupling controller. 相似文献

This study systematically reviews and summarizes relocation and revamping project of medium and heavy plate rolling mill in Bayi Steel.After detailed analysis was made on the main deficiency and problems of the original production line of Pudong Steel,systematical integration and improvement for the process and equipment were carried out accordingly.Through innovative practice of integration,Baosteel Engineering has greatly improved the technical process and equipment make-up,as well as the grades and quality of the products.The original man-operating line is redesigned into an automatic system controlled by Level 2 computer,reaching the advanced technical level of home-made medium and heavy plate production line in recent years.The project is constructed in two phases;The original product mix of Pudong Steel is maintained as much as possible in Phase I.After 3 500 mm single stand finishing mill is put into operation, capacity of hot- rolling medium and heavy plate reaches 650 000 t/a,with the maximum thickness at 40 mm.Equipment or facilities are reserved for production of pipeline steel and other grades.Pipeline steel, vessel plate,wind power plate and other TMCP and heat treatment products are projected in PhaseⅡ.After 4 200 mm roughing mill and its matched facilities are put into operation,capacity of hot-rolling medium and heavy plate will reach 120 000 t/a,with the maximum thickness at 80 mm.Through the optimization of process equipment and its function,the relocated medium and heavy plate mill production line has reached advanced level among similar domestic mills.The prominent achievements of the project are the revamping of thickness control system of the finishing mill and the newly installed shape control system.Automation control of the whole line is realized. 相似文献
