摘　　要：文章介绍了应用解析板形方程推出板形最佳轧制规程和板形板厚协调控制新方法。该方法的主要特点 :系统中采用了静、动态负荷分配 ,动态设定厚度自动控制系统 (DAGC)完成了板形板厚的闭环控制 ,在算法中采用了贝尔曼动态规划。新方法将会改变目前轧机设计和控制思想 :设计合理刚度 ,强调调度计划、配置轧辊凸度和优化轧制规程等方面的作用 。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.
