VIM）就是在真空條件下，利用電磁感應(yīng)在金屬液導(dǎo)體內(nèi)產(chǎn)生渦流加熱爐料 進(jìn)行熔煉的方法。真空冶金可保護(hù)金屬液不被大氣中氧等 氣體 物質(zhì)污染、分離沸點(diǎn)不同的物質(zhì)并可降低金屬中的氣體或其他雜質(zhì)含量等，可以實(shí)現(xiàn)在大氣壓下無(wú)法實(shí)行的冶煉過(guò)程，提高 冶煉 金屬及合金的質(zhì)量。 為了適應(yīng)尖端技術(shù)對(duì)高性能及新型金屬材料的需求，真空冶金已成為現(xiàn)代冶金的一個(gè)重要領(lǐng)域。中國(guó)的真空冶煉在 20 世紀(jì) 50年代后期開(kāi)始的，到目前，我國(guó)的真空冶金已經(jīng)處在快速發(fā)展階段。 國(guó)內(nèi)外真空感應(yīng)爐
