二辊可逆轧机液压系统控制方案

Control Plan of Hydraulic System in Two Rolls Reversible Rolling Mill

二辊可逆开坯轧机液压控制回路对轧机性能控制起着关键作用,本文详细介绍对轧机平衡缸控制回路,阐述上辊平衡液压阀台、轧机接轴平衡阀台控制方案。其主要特点是运用蓄能器与阀组配合完成平衡回路的控制,充分发挥蓄能器特点;运用插装阀、比例阀、节流阀等阀组有机组合控制平衡缸多种复杂工况;控制方案具有节能环保、设计理念先进等特点,回路控制方案为其它设备控制提供了参考,有一定的市场推广价值。

The hydraulic control circuit of two-roll reversible open-billet rolling mill plays a key role in the performance control of the rolling mill. This paper introduces the control circuit of the balance cylinder of the rolling mill in detail,and expounds the control scheme of the hydraulic balance valve station on the upper roll and the balance valve station on the rolling mill. Its main feature is the use of accumulator and valve group to complete the balance circuit control,give full play to the characteristics of the accumulator; the use of cartridge valve,proportional valve,throttle valve and other combinations of control valve balance tank a variety of complex conditions; Control programs with energy saving and environmental protection,advanced design concepts and other characteristics of the loop control program provides a reference for other equipment control,there is a certain marketing value.
