Vacuum induction melting (VIM) ke ts'ebetso ea metallurgic eo ho eona litšepe li futhumatsang le ho qhibiliha tlas'a maemo a vacuum ho sebelisoa induction ea motlakase ho hlahisa maqhubu a eddy ka har'a mokhanni. Mokhoa ona o fana ka melemo e mengata, ho kenyelletsa le kamore e qhibilihisang ea compact, lipotoloho tse khutšoane tsa ho qhibiliha le ho pompa, hammoho le taolo e nepahetseng holim'a mocheso le khatello. E boetse e lumella ho hlaphoheloa ha likarolo tse sa tsitsang le ho lokisoa ka nepo ha lipina tsa alloy. Kajeno, VIM e se e le mohato oa bohlokoa tlhahisong ea li-alloys tse khethehileng tse kang litšepe tsa lisebelisoa, li-alloys tse futhumatsang motlakase, li-alloys tse nepahetseng, li-alloys tse thibelang kutu, le li-superalloys tse phahameng tsa mocheso.
Nakong ea ts'ebetso ea VIM, palo e ngata ea phofo e ntle ea tšepe e hlahisoa. Ntle le ho hloekisa hantle, likaroloana tsena li ka huleloa ka har'a pompo ea vacuum, e leng se lebisang ho thibela le ho hlōleha ha ts'ebetso. Ho sireletsa pompo ea vacuum, ho bohlokoa ho kenya asefa pompo ea vacuumkoung ea pompo e kenang. Setlhopha sena se tšoara hantle le ho tlosa phofo ea tšepe, se netefatsa ts'ebetso e tsitsitseng le e tsoelang pele ea sistimi ea ho pompa.
Kaha VIM e hloka boemo bo phahameng ba vacuum, ho bohlokoa ho khetha pompo e sebetsang hantle haholo. Ha u khetha ntho ea filthara, ho bohlokoa ka ho ts'oanang ho nahana ka bokhabane ba filtration. Le hoja botle bo phahameng ba filtration bo thusa ho tšoara li-powders tse ntle, ha ea lokela ho eketsa ho hanyetsa ho phalla kapa ho ama boemo ba vacuum hampe, kaha sena se ka senya boleng ba sehlahisoa. Ho finyella ho leka-lekana pakeng tsa ts'ebetso ea ho hloekisa le ho boloka sekheo se hlokahalang ke senotlolo sa ho netefatsa boleng ba sehlahisoa sa ho qetela.
Ka kakaretso, pompo ea vacuumsefepi se kenange bapala karolo ea bohlokoa ts'ebetsong ea ho qhibiliha ha vacuum induction. Ka ho sefa ka katleho litšila tsa phofo ea tšepe, ha e sireletse feela pompo ea vacuum hore e se ke ea senyeha le ho boloka ts'epo ea tsamaiso empa e boetse e matlafatsa botsitso ba ts'ebetso ea ho qhibiliha le ho netefatsa boleng bo tsitsitseng ba sehlahisoa. Sena, ka lehlakoreng le leng, se tiisa ts'ebetso ea tlhahiso ka kakaretso e bonolo le e sebetsang hantle.
