Analysis of Hydraulic Roll Gap Control System for Cold Rolling Mill

HGC(液压辊缝控制)系统是AGC(厚度自动控制)系统的重要组成部分,其作用是与轧制速度控制系统、带钢张力控制系统一起保证板带材纵向厚度的均匀性和较高的厚度精度。本文针对某四机架冷连轧机液压压下系统轧制力方式下的控制模型仿真分析,研究其在轧制力控制方式下的动态特性,并为如何提高控制系统动态特性与优化调节参数提供了理论基础。

HGC （ hydraulic gauge control） system is an important part of AGC （ automatic gauge control） system, and its function is to ensure the uniformity of longitudinal thickness of plate and strip, and the higher thickness accuracy together with the roiling speed control system and the strip tension control system. By using the simulating and analyzing the four stand cold tandem roiling with the control model, the paper studies the dynamic characteristics under rolling force mode of hydraulic system. It provides theoretical basis for how to improve the dynamic characteristics of the control system and optimize the parameters.
