Study on Dynamic Characteristics of Hydraulic Pressure System of MPM Tube Rolling Mill

Abstract

Now MPM mill is widely used in hydraulic servo control technology in the field of seamless steel pipe production. But the hydraulic control system has the defect of complex control, bigger load power, more disturbance factors, higher response speed requirement and so on, which are unfavorable for analyzing the impact of factors of steel rolling precision. The conclusions show that: the system model is conducive to the analysis of the factors that affect the rolling accuracy, and it provides a theoretical basis for study the dynamic characteristics of the system, the optimal design and so on.
