Abstract：

Hydraulic gap control system is the accuracy key part for strip gauge control of compact cold rolling mill.Hydraulic screw down system is the most important part of hydraulic roll gap control.Through the research of Jigang compact cold rolling mill with hydraulic pressure system,the mathematical models of the system under the position control and force control modes were established.Analysis of time and frequency domain characteristics of the system was done with IbaAnalyzer software,and the practical dynamic characteristic performance was mastered,which laid a foundation for further optimizing the system design and control system performance research.The product accuracy improvement can be well guaranteed.
