1. Peb lub Hoobkas nyob hauv Luoyang City, Henan Province. Luoyang yog thaj chaw tsim khoom rau tungsten thiab molybdenum mines, yog li peb muaj qhov zoo ntawm qhov zoo thiab tus nqi;
2. Peb lub tuam txhab muaj cov kws tshaj lij nrog ntau tshaj 15 xyoo kev paub, thiab peb muab cov kev daws teeb meem thiab cov lus qhia rau txhua tus neeg siv khoom xav tau.
3. Tag nrho peb cov khoom raug soj ntsuam nruj ua ntej xa tawm.
4. Yog tias koj tau txais cov khoom tsis raug, koj tuaj yeem tiv tauj peb kom them rov qab.
1. raw khoom npaj
(Cov khoom siv raw no yuav tsum tau ua kom tau raws li tus qauv purity, feem ntau yuav tsum muaj purity ntawm Mo ≥ 99.95%)
2. cov khoom lag luam dawb
(Load cov ntaub ntawv raw rau hauv pwm los npaj cov khoom cylindrical billet, thiab tom qab ntawd nias rau hauv lub cylindrical billet)
3. sinter
(Tej qhov chaw ua tiav rau hauv qhov nruab nrab zaus sintering rauv, thiab qhia cov roj hydrogen rau hauv lub qhov cub. Qhov cua sov yog 1900 ℃ thiab lub sijhawm cua sov yog 30 teev. Tom qab ntawd, siv cov dej ntws kom txias rau 9-10 teev, txias rau chav tsev kub, thiab npaj lub cev molded rau tom qab siv)
4. Forging thiab sib sau
(Tsuas yog cov ntawv tsim los rau 1600 ℃ rau 1-3 teev, tom qab ntawd tshem tawm thiab forge nws mus rau hauv cov duab crucible kom tiav cov khoom ntawm molybdenum crucible)
Kev tshawb fawb txog kev tshawb fawb: Molybdenum crucibles muaj ntau yam kev siv hauv kev tshawb fawb txog kev tshawb fawb. Ua ntej, nws ua lub luag haujlwm tseem ceeb hauv kev sim tshuaj, vim tias molybdenum crucibles tau siv dav hauv kev sim ntsuas kub thiab tshuaj lom neeg vim lawv qhov kub thiab txias stability thiab corrosion kuj. Hauv cov ntaub ntawv tshawb fawb, molybdenum crucibles tau siv dav hauv cov txheej txheem xws li melting thiab solid-state sintering. Piv txwv li, nyob rau hauv cov txheej txheem melting ntawm cov hlau alloys, molybdenum crucibles tuaj yeem tiv taus qhov kub thiab txias thiab ruaj khov, ua rau kev npaj cov hlau alloys ntau dua thiab tswj tau.
Tsis tas li ntawd, nyob rau hauv kev tsom xam thermal thiab kev ua tau zoo ntawm cov qauv ntawm cov khoom siv, molybdenum crucibles kuj yog ib qho tseem ceeb ntawm cov qauv ntim, muab ib qho chaw ruaj khov ntawm qhov kub thiab txias thiab ua kom qhov tseeb ntawm cov ntaub ntawv xeem.
Kev siv tsis raug: Yog tias qhov kub thiab txias poob sai heev thaum siv, qhov kev ntxhov siab tshwm sim los ntawm qhov sib txawv ntawm qhov kub thiab txias ntawm cov phab ntsa sab nrauv thiab sab hauv siab tshaj qhov ntau ntawm cov crucible tuaj yeem tiv taus, uas tuaj yeem ua rau tawg. cov
Yog, nws muaj peev xwm ua kom sov molybdenum crucible rau liab kub. Molybdenum muaj qhov siab melting point ntawm 2,623 degrees Celsius (4,753 degrees Fahrenheit), uas tso cai rau nws tiv taus kub heev yam tsis muaj melting. Qhov no ua rau molybdenum crucibles haum rau daim ntaub ntawv uas yuav tsum tau cua sov rau liab-kub kub, xws li melting ntawm hlau, iav, los yog lwm yam high-temperature txheej txheem. Txawm li cas los xij, nws yog ib qho tseem ceeb kom ntseeg tau tias lub crucible yog siv nyob rau hauv nws qhov ntsuas kub thiab ntsuas kev nyab xeeb kom raug thaum siv cov crucible kub liab.
Nws yog ib qho tseem ceeb kom sov lub crucible maj mam thaum thawj feeb kom tsis txhob thermal shock. Thaum lub crucible txias raug kub heev sai heev, nws tuaj yeem ua rau qhov tsis sib xws thiab thermal stress, uas tuaj yeem ua rau crucible tawg los yog tawg. Txo qhov kev pheej hmoo ntawm kev poob siab thermal thiab xyuas kom meej lub siab ntawm lub crucible thaum lub sij hawm cua sov los ntawm cua sov lub crucible maj mam thaum pib thiab maj mam coj mus rau qhov xav tau kub. Txoj hauv kev no pab txuas ntxiv lub neej ntawm lub crucible thiab tswj nws txoj kev ncaj ncees rau kev rov siv dua.
