Ukunyibilika kwe-vacuum induction melting (VIM) yinkqubo yetsimbi apho izinyithi zifudunyezwa kwaye zinyibilike phantsi kweemeko zevacuum kusetyenziswa i-electromagnetic induction ukuvelisa imisinga eddy ngaphakathi komqhubi. Le ndlela inika iingenelo ezibalulekileyo, kubandakanywa negumbi lokunyibilikisa elidibeneyo, imijikelezo emfutshane yokunyibilika kunye nokumpompa, kunye nolawulo oluchanekileyo lobushushu kunye noxinzelelo. Kwakhona kuvumela ukubuyiswa kwezinto eziguquguqukayo kunye nokulungelelaniswa ngokuchanekileyo kweengoma ze-alloy. Namhlanje, i-VIM iye yaba linyathelo elibalulekileyo ekuvelisweni kwee-alloys ezikhethekileyo ezifana neentsimbi zesixhobo, ii-alloys zokufudumeza zombane, ii-alloys ezichanekileyo, i-alloys enganyangekiyo kwi-corrosion, kunye ne-high-temperature superalloys.
Ngethuba lenkqubo ye-VIM, inani elikhulu le-powder yensimbi ecocekileyo yenziwa. Ngaphandle kokucoca okufanelekileyo, la maqhekeza angatsalwa kwimpompo ye-vacuum, ekhokelela kwiibhlokhi kunye nokungaphumeleli kokusebenza. Ukukhusela impompo yokufunxa, kubalulekile ukufakela i-aisihluzi sempompo yokucocakwindawo yokungena yempompo. Esi sihluzo sibambe ngokufanelekileyo kwaye sisuse ii powders zetsimbi, siqinisekisa ukusebenza kakuhle kunye nokuqhubekayo kwenkqubo yokupompa.
Ekubeni i-VIM idinga inqanaba eliphezulu le-vacuum, ukukhetha ipompo yokucoca i-vacuum ephezulu kubalulekile. Xa ukhetha into yokucoca, kubalulekile ngokulinganayo ukuqwalasela ukucolwa kokucoca. Ngelixa ukucocwa okuphezulu kokucoca kunceda ukubamba umgubo ocolekileyo, akufuneki kunyuse kakhulu ukuchasana nokuqukuqela okanye kuchaphazele kakubi umgangatho wevacuum, njengoko oku kunokonakalisa umgangatho wemveliso. Ukufezekisa ukulingana phakathi kokusebenza kokucoca kunye nokugcina i-vacuum efunekayo ngundoqo ekuqinisekiseni umgangatho wemveliso yokugqibela.
Isishwankathelo, impompo yokucocaisihluzi sokungenaidlala indima ebalulekileyo kwinkqubo yokunyibilika kwevacuum induction. Ngokucoca ngokufanelekileyo ukungcola komgubo wesinyithi, akugcini nje ukukhusela ipompo yokucoca kumonakalo kwaye igcina ukuthembeka kwenkqubo kodwa iphakamisa ukuzinza kwenkqubo yokunyibilika kunye nokuqinisekisa umgangatho wemveliso ohambelanayo. Oku, kuqinisekisa ukusebenza ngokutyibilikayo kunye nokusebenza kakuhle kwemveliso iyonke.
