    摘要:

    卷取机前夹送辊是热轧带钢生产线上的一个重要设备,该设备的性能直接影响着卷材的卷取质量。通过分析卷取机前夹送辊工作原理及液压伺服单、双腔两种控制回路,建立单、双腔液压伺服控制回路仿真模型,在相同条件下进行仿真分析,通过对位置和压力闭环仿真曲线和实际生产曲线的对比分析,得出单腔控制回路的稳定性优于双腔控制回路、而双腔控制回路的快速性优于单腔控制回路的结论。

    Abstract:

    The pinch roll before coiler is the important equipment in hot strip mill. Its performance directly affects the quality of coil. The principles of the pinch roller and the singlechamber and dualchamber servo hydraulic control loops were analyzed. The simulation models of the singlechamber and dualchamber servo hydraulic control loops were established. Under the same conditions of simulation analysis, by comparing the position and pressure closedloop simulation curves with the actual production curves, the conclusion is that the stability of the singlechamber control loop is better than that of the dualchamber control loop, but the rapid response of the dualchamber control loop is better than that of the singlechamber control loop.
