Molybdenum crucible yog dav siv nyob rau hauv lub ntiaj teb tsis tshua muaj, nqus tsev, tshuaj lom neeg kev lag luam, kuaj thiab kub ua kev lag luam thiab lwm yam teb, tab sis vim hais tias molybdenum muaj ib tug siab melting point, siab zog yam ntxwv, yog li cov txheej txheem ntawm molybdenum khoom muaj ib tug tej yam nyuaj. Txoj kev ua yog raws li nram no:
Molybdenum crucible yog dav siv nyob rau hauv lub ntiaj teb tsis tshua muaj, nqus tsev, tshuaj lom neeg kev lag luam, kuaj thiab kub ua kev lag luam thiab lwm yam teb, tab sis vim hais tias molybdenum muaj ib tug siab melting point, siab zog yam ntxwv, yog li cov txheej txheem ntawm molybdenum khoom muaj ib tug tej yam nyuaj. Txoj kev ua yog raws li nram no:
1. Plasma txau txoj kev
Cov hmoov yog npaj los ntawm pob milling thiab tshuaj tsuag kom qhuav, thiab tom qab ntawd cov hmoov yog ua tiav rau hauv molybdenum deposit txheej nrog ib tug predetermined thickness los ntawm plasma spraying, thiab ces cov deposit txheej yog kho los ntawm kub isostatic nias. Qhov kawg molybdenum crucible uas ua tau zoo seem stability, muaj zog txhua yam khoom, tab sis siab raw khoom noj thiab tus nqi siab.
2. Casting txoj kev
Molybdenum yog thawj zaug ua rau hauv electrodes, thiab tom qab ntawd yaj mus rau hauv cov kua hauv lub tshuab nqus tsev vacuum thiab molded rau hauv cov qauv txhaj tshuaj. Cov txheej txheem tuaj yeem ua tiav qhov kev npaj ntawm ntau qhov ntau thiab tsawg ntawm molybdenum crucible, txuag cov ntaub ntawv raw, tab sis cov txheej txheem kev npaj yog complex, yuav tsum tau ua kom muaj ntau cov pwm, thiab molybdenum melting point yog siab, yuav tsum tau siv ntau lub zog los yaj nws. .
3. Stamping txoj kev
Siv cov yas ntawm molybdenum slab nyob rau hauv cua sov, lub crucible tau npaj los ntawm txheej txheem stamping. Nws cov khoom siv tus nqi tuaj yeem ncav cuag 75 feem pua. Txawm li cas los xij, nws yog qhov tsim nyog rau kev ua crucible nrog cov phab ntsa loj, thiab nws yog ib qho nyuaj rau cov txheej txheem crucible nrog loj loj thiab nyias phab ntsa.
4. Vuam txoj kev
Raws li qhov loj ntawm qhov yuav tsum tau crucible, ib daim ntawv haum molybdenum tau txais, thiab daim ntawv tau rhuab nyob rau hauv hydrogen rauv, thiab tooj liab hauv qab tau stitched nrog lub vuam lub tog raj kheej ntawm lub tshuab nqus tsev vuam lub thawv. Cov txheej txheem muaj qhov zoo ntawm tus nqi qis, cov txheej txheem tsim khoom yooj yim thiab tsim nyog qhov tseeb. Txawm li cas los xij, qhov vuam crucible yog ib qho yooj yim tawg ntawm lub vuam thaum siv, uas yuav txo tau lub neej kev pab cuam ntawm lub crucible.
5. Sintering txoj kev
Molybdenum thiab nws cov hmoov hlau alloy yog tsim los ntawm isostatic nias, tig thiab shaping, thiab tom qab ntawd sintering los ntawm kub kub. Cov txheej txheem muaj kev siv siab ntawm cov ntaub ntawv raw, siab precision thiab ruaj khov khoom ntawm cov khoom tsim crucible. Txawm li cas los xij, lub crucible yog ib qho yooj yim rau deform nyob rau hauv sintering molding, thiab qhov loj ntawm crucible loj thiab lub thinner phab ntsa thickness, qhov ntau yuav deform. Ntxiv mus, lub hav zoov ntawm pores nyob rau hauv cov txheej txheem sintering yuav cuam tshuam lub zog thiab kev pab lub neej ntawm molybdenum crucible.
