介绍了某钢厂RH精炼炉液压顶系统的工作原理,针对顶升双油缸“不同步”问题,进行了改造,增加了电气找平程序,并在故障状态通过增加的人工球阀实现双缸的平稳下降。改造后工作可靠性增加。
This paper introduces the working principle of hydraulic top system of a RH refining furnace in a steel mill, rebuilds the double jacking cylinder with “unsynchronized” lifting, increases the electrical leveling procedure and realizes the double cylinder by the added artificial ball valve The steady decline. Improved reliability of the work after transformation.
