Abstract

PURPOSE: To improve the stability of successive operations in the speed controlling of continuous rolling mills by performing smoothing processing conforming to the time constants of the responsiveness of looper control function and tension value control function.
CONSTITUTION: In the case of performing the speed correction V2" of #2 stand for the purpose of correction of disturbances when all the stands are in an equilibrium relation at speeds V1, V2... at a certain insant during sheet material rolling, the following processing is carried out. Namely, with respect to the loops between the stands including pivot stands, dividers 91W93 leading out the speed ratios of rolling stands at both ends thereof and smoothers 101W103 are provided, and pivot stand speeds are changed by the output from a accelerating and decelerating speed setter 11 differing from a pass speed setter 1. At the same time, the speeds of the next stands adjacent to the pivot stands are changed by the product of the output value smoothing the abovementioned divider outputs and the pivot stand speed change amount, whereby the speed change (accelerated and decelerated rolling) of the entire part of the continuous rolling mills is realized.
