Ubuchwepheshe be-vacuum busetshenziswe ngokugcwele emkhakheni we-metallurgy, futhi bukhuthaza ukusetshenziswa nokuthuthukiswa kwemboni ye-metallurgical.
Ngenxa yokusebenzelana kwamakhemikhali phakathi kwezinto nama-molecule egesi ayinsalela abuthakathaka ku-vacuum, indawo ye-vacuum ifaneleka kakhulu ukuncibilika nokucwengisiswa kwezinsimbi ezimnyama, izinsimbi ezingavamile, izinsimbi ezihlanzekile kakhulu kanye nama-alloys azo, kanye nezinto zokwakha ze-semiconductor. Amaphampu e-vacuum asetshenziswa embonini ye-metallurgical ukuncibilika kwe-vacuum, ukuchithwa kwensimbi, ukufakwa kwe-vacuum sintering, ukuncibilika kwesithando somlilo, ukucisha igesi ecindezelwe nge-vacuum, ukwelashwa kokushisa kwe-vacuum, njll.Izihlungi zephampu ye-vacuumnazo zilandelwa eduze. Okulandelayo, ake sethule kafushane ezinye izinhlelo zokusebenza ze-vacuum embonini ye-metallurgical.
I-High Purity Metal Extraction: Enqubweni yokukhiqiza ingxubevange, hlukanisa i-ejenti evikelayo evikela insimbi ekufakweni kwe-oxid ku-vacuum. Isibonelo, ekukhiqizeni i-tungsten alloy, i-parafini wax kanye ne-alcohol solvents isetshenziselwa ukuvimbela i-oxidation ye-tungsten alloy powder. Ngaphambi kokushisa, i-solvent idinga ukukhishwa ku-vacuum futhi ifakwe emabhuloki esithandweni somlilo, esidinga usizo lwamaphampu we-vacuum nezihlungi.
I-Vacuum Induction Furnace Melting: Imisinga ye-Eddy ikhiqizwa ngesikhathi sokungeniswa kwe-electromagnetic ku-vacuum, bese incibilikisa insimbi. Ngokusebenzisa umgomo wokushisisa kwe-intermediate frequency induction, singakwazi ukukhipha izinsimbi nama-alloys ahlanzekile kakhulu. Kungathuthukisa kakhulu ukuqina kwazo, ukumelana nokugqwala, nezinye izakhiwo. Phakathi nale nqubo, enye impushana yensimbi ivamise ukumuncwa empompini ye-vacuum, ngakho ngokuvamile kuyadingeka ukufaka i-isihlungi sokungena.
Ukusetshenziswa kobuchwepheshe be-vacuum kuyehluka ezimbonini ezihlukene, futhi izimo ezidingekayo ze-vacuum kanye namamodeli wepompo ye-vacuum ahlukile ngokwemvelo. Amabhizinisi obuchwepheshe be-vacuum kuphela angakwazi ukuzivumelanisa nokuthuthukiswa kwemboni angasiza ukukhuthaza ukuthuthukiswa kobuchwepheshe be-vacuum. Ngakho-ke, abathengisi bepompo ye-vacuum bathuthukisa imikhiqizo efanelekile ukuhlangabezana nalezi zidingo ezahlukene. Siphinde senze ngokwezifiso izixazululo ezifanele zokuhlunga ngokwezidingo zamakhasimende kanye nezimo zokusebenza.
