摘要

新钢第二炼钢厂VD炉在炼钢过程中真空度出现了反弹现象,达不到工艺要求的真空度,直接影响到VD炉钢水脱氢效果和铸坯质量。依据真空系统设备获得真空度的工作原理,通过对真空度影响因素的逐项排查,分析研究了真空泵积灰的形成以及泵体积灰对真空度的影响,为真空设备的正常运行和科学维护提供了保障。
        The condition of vacuum degree rebounce appears for VD furnace in the process of steelmaking,which can not reach the required vacuum degree. It will directly affects the dehydrogenation effect of liquid steel and slab quality. According to the working principle of the equipments of vacuum system,troubleshooting are made for the influence factors for vacuum degree one by one.The form of ash deposition on vacuum pump and its influence on the vacuum degree are analyzed. Guarantee is provided for the normal operation and scientific maintenance of the vacuum equipment.
