Cov khoom siv hauv paus yog ua los ntawm 99.9995% ultra- ntshiab graphite hmoov (D50=3μm ultra-} cov khoom zoo), uas yog tsim los ntawm cov ntawv thov siab ntawm 250MPa thoob plaws hauv cheeb tsam. Qhov ceev tuaj yeem ncav cuag 1.92–1.95g / cm³, nrog cov ntsiab lus seem ntawm Tsawg dua lossis sib npaug li 8ppm, thiab tsis muaj kab mob alkali hlau lossis hlau hnyav. Cov khoom no tshwj xeeb hais txog peb qhov kev mob tseem ceeb ntawm kub smelting: leakage poob ntawm cov kua kub vim micro- pores nyob rau hauv lub crucible phab ntsa, cuam tshuam rau kub purity vim impurity tsiv teb tsaws, thiab kev nyab xeeb xwm txheej tshwm sim los ntawm thermal shock cracking. Nws yog sib xws nrog cov khoom siv hluav taws xob kub kub xws li nruab nrab- zaus induction furnaces, muffle furnaces, thiab lub tshuab nqus tsev vacuum arc furnaces. Nws yog qhov nyiam tshaj plaws -purity kub melting thawv rau thoob ntiaj teb cov hniav nyiaj hniav kub factories, precious hlau refineries, thiab geological kuaj.
Precise casting crucible rau cov hniav nyiaj hniav kub zoo nkauj (1-5kg, me me - nplai siab - daim ntawv thov zaus)
Haum rau cov chaw lag luam hniav nyiaj hniav kub rau 1-5kg kub / platinum / nyiaj me me -batch precision casting. Nws txais yuav nyias-phab ntsa isostatic nias tshuab, nrog cov phab ntsa tuab sib txawv ntawm Tsawg dua lossis sib npaug li 0.1 hli. Hauv qab muaj ib qho arc-zoo li tus qauv hloov pauv yam tsis muaj cov fab tuag, ua kom cov kua dej ntws zoo tsis muaj qhov seem thiab cov hlau rov qab tau ntau dua 99.98%.
Sab hauv phab ntsa yog kho nrog daim iav polishing (Ra tsawg dua lossis sib npaug ntawm 0.2μm), uas tsis yog - lo rau cov kua kub thiab yooj yim rau demould, txo cov txheej txheem sib tsoo tom ntej. Nws yog txawm peem rau nrog ib tug tshwj xeeb graphite npog kom txo tau kub evaporation poob (tsawg tshaj los yog sib npaug rau 0.015% ib lub voj voog cub tawg). Nws yog sib xws nrog nruab nrab- zaus induction rauv rau cov cua sov ceev (cov cua kub txog li 120℃/ min), ua tau raws li qhov yuav tsum tau ua rau nquag thiab me me -batch tsim cov hniav nyiaj hniav kub.
High-purity molten kub crucible rau precious hlau refineries (10-50kg nruab nrab- loj loj nruam ntau lawm)
Rau cov txheej txheem ntawm crude kub purification thiab electrolytic kub ingot casting nyob rau hauv kub refineries, ib tug thickened siab - ceev isostatic nias graphite substrate yog saws. Lub sijhawm tiv thaiv - lub sijhawm poob siab yog ntau dua lossis sib npaug li 1200 zaug (1600℃↔ chav tsev kub), thiab nws tuaj yeem siv tsis tu ncua rau 80 qhov cub yam tsis muaj qhov tawg lossis deformation.
Ultra- cov ntsiab lus tsis tshua muaj tshauv (tsawg dua lossis sib npaug li 8ppm) + tsis muaj alkali hlau impurities (Na/K Tsawg dua lossis sib npaug li 0.002ppm), ua kom ntseeg tau 99.999% siab-purity kub tso zis; Cov qauv tsim tshwj xeeb ntws, tso cai rau cov kua kub tsis muaj dej tsis muaj txaws, haum rau cov kab ntau lawm hauv cov refineries, txo cov kev siv ntawm phau ntawv ua haujlwm thiab nce ntau lawm efficiency los ntawm 30%.
Kev kuaj tshwj xeeb crucible rau micro- tsom xam kub (10–500g ultra-me me siab-precision)
Tsim los rau kev tshawb nrhiav geological, metallurgical tsom xam, thiab cov chaw tshawb fawb, qhov no ultra-me me kub melting crucible muaj peev xwm tsawg kawg nkaus ntawm tsuas yog 10g thiab yog sib xws nrog cov khoom siv hauv chav kuaj xws li lub raj rauv thiab lub thawv rauv, ua tau raws li qhov yuav tsum tau ua rau melting, ashing, thiab enrichment tsom xam ntawm micro-cov qauv kub.
Nws siv spectral -qib graphite raw cov ntaub ntawv thiab tau txais kev kho lub tshuab nqus tsev degassing. Cov pa pa tawm ntawm 1200℃tsawg dua 5 × 10⁻¹ Pa·m³ / s, tsis muaj cov pa roj carbon- cov tshuaj hydrogen volatile uas paug cov qauv. Nws tau raug tsim los nrog kev kawm tiav, ua kom muaj txiaj ntsig zoo ntawm cov qauv ntsuas kub, thiab tuaj nrog kev kho kom haum rau crucible clamps kom muaj kev nyab xeeb thiab yooj yim ua haujlwm.
