Lub tshuab nqus tsev melting txhim kho cov txheej txheem induction melting los ntawm kev kaw lub qhov cub hauv lub tshuab nqus tsev, feem ntau ua haujlwm ntawm 10 Torr. Qhov chaw no cais cov txheej txheem melting los ntawm atmospheric contaminants, kom ntseeg tau tias muaj kev tswj hwm huab cua uas txo cov oxidation thiab cov kab mob sib kis, uas ua rau kev txhim kho yaj zoo.
Qhov zoo ntawm Vacuum Melting
Los ntawm leveraging electromagnetic stirring ua ke nrog lub tshuab nqus tsev ib puag ncig, cov txheej txheem no zoo tshem tawm cov pa roj xws li hydrogen thiab oxygen los ntawm cov hlau, tiv thaiv oxidation thaum lub sij hawm melting thiab casting. Qhov no ua kom muaj kev sib faib ntawm cov khoom siv thiab kev ua kom tsis muaj kev sib koom ua ke. Tsis tas li ntawd, kev muaj peev xwm ntxiv cov ntaub ntawv thaum lub sij hawm melting txheej txheem tsis raug rau oxygen txhim kho qhov tseeb thiab sib xws ntawm cov khoom kawg.
Qhov tshwm sim yog cov hlau los yog alloy nrog superior purity, txhim kho corrosion kuj, thiab kev ua tau zoo dua nyob rau hauv thermal stresses thiab qaug zog. Txawm li cas los xij, lub tshuab nqus tsev melting tuaj nrog cov nqi ua haujlwm ntau dua vim lub sijhawm xav tau los tsim thiab tswj lub tshuab nqus tsev, nrog rau qhov yuav tsum tau ua rau cov chaw taws teeb them nqi thiab nchuav cov yaj. Txawm tias cov nqi no, lub tshuab nqus tsev melting tseem yog ib qho kev daws teeb meem tshwj xeeb rau cov ntawv thov xav tau cov khoom tshwj xeeb.
Daim ntawv thov thiab cov ntaub ntawv zoo tagnrho rau lub tshuab nqus tsev Melting
Lub tshuab nqus tsev melting feem ntau yog siv rau hauv kev tsim cov alloys siab heev, suav nrog superalloys, tshwj xeeb steels, thiab siab - purity hlau. Nws yog tshwj xeeb tshaj yog haum rau kev tsim npib tsib xee- thiab cobalt-raws li superalloys, xws li Inconel, Vaspanu, thiab Atimet, nrog rau siab - steels zoo li stainless hlau, Manain steel, thiab siab - steel ceev. Cov txheej txheem kuj tseem ceeb heev rau kev tsim cov high-purity hlau xws li npib tsib xee, cobalt, uranium, thiab beryllium, uas yog ib qho tseem ceeb rau ntau yam ntawm kev txiav- ntug daim ntawv thov.
Tsis tas li ntawd, lub tshuab nqus tsev yog qhov zoo tagnrho rau kev tsim cov hlau alloys xws li tooj liab-chromium, tooj liab-titanium, hlau-titanium, thiab hlau-chromium, nrog rau cov ntaub ntawv precision xws li Invar thiab Eurispa. Cov txheej txheem yog qhov tseem ceeb rau siab -purity magnetic alloys, suav nrog μ hlau thiab hlau-cobalt-vanadium alloys, nrog rau cov hlau reactive xws li titanium, aluminium, thiab zirconium. Cov hlau thiab cov hlau no tuaj yeem muab ntxiv rau hauv cov yaj hauv kev tswj xyuas siv lub kaw lus them nyiaj, khaws cia lub tshuab nqus tsev thiab tiv thaiv oxidation.
Khoom siv thiab kev ua haujlwm nta
Lub tshuab nqus tsev niaj hnub no muaj peev xwm ua tau ntau yam ntawm cov khoom siv, muaj peev xwm ntawm 300 txog 5000 kg ntawm steel. Lub cub tawg chamber feem ntau yog tsim los ntawm cov hlau tsis muaj steel, txo qhov kev xav tau ntawm cov hlau nplaum tiv thaiv, txawm hais tias cov cub tawg loj tseem yuav xav tau nws. Ntau lub tshuab nqus tsev vacuum feature pwm interlock tshuab, tso cai pwm tuaj yeem npaj sab nraum lub tshuab nqus tsev thiab tom qab ntawd xa mus rau hauv cov txheej txheem kaw thaum lub tshuab nqus tsev tsim. Cov kab ke no, ua ke nrog kev them nyiaj xauv lub tshuab, ua kom muaj kev ua haujlwm tas mus li yam tsis muaj kev rov ua dua tshiab - khiav tawm ntawm lub qhov cub chamber.
Cov cuab yeej tshwj xeeb no ua kom ntseeg tau tias lub tshuab nqus tsev melting tseem yog ib txoj hauv kev ua tau zoo thiab meej rau kev tsim cov khoom ua haujlwm siab - nrog cov khoom tshwj xeeb.
