Hydraulic AGC is one of the key equipment for controlling the geometric dimension accuracy of modern cold strip tandem cold rolling mill. Taking the hydraulic pressure AGC of one meter and seven tandem cold rolling mill as the research object, the mathematical model of the hydraulic pressure reduction system was established. The time and frequency characteristics of the system were analyzed. The influence of the system’s main factors on the dynamic characteristics was studied. Effect of Improvement Measures on Hydraulic AGC System of Rolling Mill.
