Ukuncibilika kwe-vacuum induction melting (VIM) kuyinqubo ye-metallurgical lapho izinsimbi zishiselwa futhi zincibilike ngaphansi kwezimo ze-vacuum kusetshenziswa ukungeniswa kwe-electromagnetic ukukhiqiza imisinga eddy ngaphakathi komqhubi. Le ndlela inikeza izinzuzo ezibalulekile, kufaka phakathi ikamelo elincibilikayo elihlanganisiwe, imijikelezo emifushane yokuncibilika nokumpompa, kanye nokulawula okunembile phezu kwezinga lokushisa nokucindezela. Iphinde ivumele ukutholwa kwezinto eziguquguqukayo kanye nokulungiswa okunembile kwezingoma ze-alloy. Namuhla, i-VIM isiyisinyathelo esibalulekile ekukhiqizeni ama-alloys akhethekile njengezinsimbi zamathuluzi, ama-alloys kagesi okufudumeza, ama-alloys anembile, ama-alloys angagqwali, nama-superalloy aphezulu.
Phakathi nenqubo ye-VIM, inani elikhulu le-powder yensimbi enhle liyakhiqizwa. Ngaphandle kokuhlunga okufanele, lezi zinhlayiya zingadonselwa kupompo ye-vacuum, okuholela ekuvinjweni nasekuhlulekeni kokusebenza. Ukuze uvikele iphampu ye-vacuum, kubalulekile ukufaka aisihlungi sepompo ye-vacuumendaweni yokungena yephampu. Lesi sihlungi sithwebula futhi sisuse izimpushana zensimbi, siqinisekise ukusebenza okushelelayo nokuqhubekayo kwesistimu yokumpompa.
Njengoba i-VIM idinga izinga eliphezulu le-vacuum, ukukhetha ipompo ye-vacuum esebenza kahle kubalulekile. Lapho ukhetha into yokuhlunga, kubalulekile ukucabangela ukucoleka kokuhlunga. Nakuba ukuhlunga okuphezulu kusiza ukuthwebula izimpushana ezinhle, akumele kukhuphule kakhulu ukumelana nokugeleza noma kuthinte kabi izinga le-vacuum, njengoba lokhu kungase kuphazamise ikhwalithi yomkhiqizo. Ukuzuza ibhalansi phakathi kokusebenza kokuhlunga nokugcina isikhala esidingekayo kubalulekile ekuqinisekiseni ikhwalithi yomkhiqizo wokugcina.
Ngamafuphi, ipompo ye-vacuumisihlungi sokungenaidlala indima ebalulekile enqubweni yokuncibilika kwe-vacuum induction. Ngokuhlunga ngempumelelo ukungcola okuyimpuphu yensimbi, akuvikeli nje kuphela ipompo ye-vacuum emonakalweni futhi igcine ukwethembeka kwesistimu kodwa futhi ithuthukisa ukuzinza kwenqubo yokuncibilika futhi iqinisekisa ikhwalithi yomkhiqizo engaguquki. Lokhu-ke, kuqinisekisa ukusebenza okubushelelezi nokusebenza kahle kokukhiqiza sekukonke.
