Method for recycling rhenium-containing high-temperature alloy powder

The invention belongs to the technical field of vacuum smelting, and discloses a recycling method of rhenium-containing high-temperature alloy powder. Comprising the steps of powder vacuum hot pressing sintering, electron beam horizontal furnace smelting, surface processing and component analysis, vacuum induction smelting and the like. According to the method, electron beam smelting is adopted, the content of harmful gases such as O, N and S and impurity elements in the Re-containing high-temperature alloy powder can be greatly reduced, the content of the O and N elements can be controlled within 5 ppm, and the content of the S element can be controlled within 1 ppm. By adopting the method disclosed by the invention, the yield of the rhenium element is greater than 99.0%, and the recycling of the rare and noble metal rhenium element is realized. 本发明属于真空冶炼技术领域，公开了一种含铼高温合金粉末的回收再利用方法。包括粉末真空热压烧结、电子束水平炉熔炼、表面加工及成分分析、真空感应熔炼等步骤。本发明通过采用电子束熔炼，可极大降低含Re高温合金粉末中的O、N、S等有害气体及杂质元素含量，其中O、N元素均可控制在5ppm以内，S元素可控制在1ppm以内。采用本发明所述的方
