Dynamic Setting Automatic Control System for Flatness and Gauge
Zhang Jinzhi、 Duan Chunhua
In this paper, the shape optimal rolling schedule and new method of shape and gauge coordination control, which are inferred from the newbuilt analytic shape equation, are introduced. This method´s characteristics is that shape and gauge close-circuit control is achieved by means of static load distribution, dynamic load distribution and dynamic setting Automatic Gauge Control (AGC), and Bellman dynamic programming is employed in calculation. The new method will change the present design thoughts on roller manufacture : transforming from high stiffness into proper sitiffness. According to the analysis results from the economic benefits, free rolling, which are propagated and pursued, in steel rolling circles is a misleading, so custom dispatch plan, making up roll crown and optimize rolling schedule should be developed. Because the former is of high investment and high consumption, the latter are no investment and no consumption, and can make full use of information flow.
