摘　　要：结合特种合金实际生产过程,从设备配置、抽空能力等方面对德国ALD公司VIDP炉真空系统进行分析,并给出了若干优化应用措施。提出将罗茨泵的启停间隙控制在120~180 s;低真空系统两套并联泵组的模式开关开启阈值分别设定为1000 Pa和2500 Pa;根据特种合金易挥发的特性,给出罗茨泵各部位维修保养周期(3~12个月不等),以及合金熔炼过程中充氩破空的具体操作流程;最后针对VIDP-300型炉的真空系统提出提升抽空能力的改造建议。Combining with the manufacturing process of special alloy,the vacuum system of VIDP furnace from ALD was analyzed according to the configuration and vacuum pumping capacity,and several optimization application measures were proposed.The interval time of Roots pump is set to 120-180 s.The starting up threshold of two paralleling pump units of low vacuum system is set to 1000 Pa and 2500 Pa.Different maintenance period(3-12 months)for different components of Roots pump and the specific operation process of filling argon to break the vacuum during alloy melting are provided according to volatile characteristics of special alloy.At last,suggestions for improving the ability of vacuum system of the VIDP-300 furnace are proposed.
