Kev tsim cov molybdenum crucibles los yog crucibles rau melting feem ntau muaj ob peb kauj ruam tseem ceeb. Txoj kev tsim khoom tau sau tseg raws li hauv qab no:

1. Kev xaiv cov khoom siv: High-purity molybdenum raug xaiv los ua cov khoom siv raw rau crucible ntau lawm vim nws zoo heev kub tsis kam thiab tsis tshua muaj thermal expansion coefficient. Hmoov metallurgy: Xaiv cov hmoov molybdenum yog nias thiab sintered ntawm qhov kub thiab txias los tsim cov khoom thaiv. Machining: Lub sintered molybdenum thaiv yog tom qab ntawd siv cov cuab yeej tshwj xeeb kom tau txais cov duab xav tau thiab qhov loj ntawm lub crucible lossis lub lauj kaub. Annealing: Cov txheej txheem crucible yog annealed ntawm qhov kub thiab txias kom tshem tawm cov kev ntxhov siab sab hauv thiab txhim kho nws cov khoom siv kho tshuab. Kev kho deg: Rau qee qhov kev siv, qhov saum npoo ntawm lub crucible yuav raug kho xws li polishing los yog txheej los txhim kho nws cov kev ua tau zoo, txhim kho corrosion kuj, los yog pab txhawb kev tso tawm cov khoom molten. Kev Tswjhwm Zoo: Thoob plaws tag nrho cov txheej txheem tsim khoom, kev tswj xyuas nruj nruj yog siv los xyuas kom meej tias qhov kawg crucible ua tau raws li qhov xav tau tshwj xeeb thiab cov qauv kev ua haujlwm.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov ntsiab lus tshwj xeeb ntawm txoj kev tsim khoom tuaj yeem sib txawv nyob ntawm qhov xav tau siv, qhov loj thiab tsim cov cai ntawm molybdenum crucible lossis crucible.
