ABSTRACT:This paper describes in detail the design of rolling equipment of pressing mechanism, the dynamic system for the hydraulic system. The first analysis of the hydraulic pressure working principle and working mechanism of. Then the design of hydraulic system, the original system selection, checking and verification, finally drawing the hydraulic system diagram and pressing mechanism assembly drawing. Do the design is reasonable, to meet the process requirements, cost requirements.
This design aimed at hot strip thickness accuracy control and roll thickness position deviation of design and diagnosis. Mainly through the design of hydraulic system and calculation of the hydraulic cylinder size, a reasonable choice of hydraulic components to achieve the accuracy of thickness precision control. The design will be described in detail the design and calculation process of hydraulic pressure mechanism, to show the application of the hydraulic servo system in rolling equipment, as well as the advantages of hydraulic servo system. At the same time also reflects the modern hydraulic AGC in iron and steel industry, especially steel part of the indispensable thickness precision control.
