Nyob rau hauv xyoo tas los no, ntau lawm technology ntawm domesticgraphite cruciblestau ua kom muaj kev vam meej.Tsis tsuas yog lawv ntes tau nrog cov crucibles txawv teb chaws, tab sis nyob rau hauv qee kis txawm tshaj lawv.Los ntawm kev siv cov txheej txheem tsim tshiab thiab nrhiav cov khoom siv zoo, graphite crucibles tam sim no tuaj yeem tiv taus huab cua nrog kev ua haujlwm tsis sib xws.
Cov yam ntxwv tseem ceeb ntawm cov tshiab graphite crucibles yog undoubtedly tsim nyog sau cia.Ua ntej, lawv muaj cov thermal conductivity, txo cov sij hawm melting, ua tsaug rau kev siv cov khoom siv raw xws li graphite, uas muaj thermal conductivity zoo heev.Qhov kev nce hauv kev ua tau zoo no tsis yog tsuas yog txuag lub sijhawm thiab lub zog, tab sis kuj ua rau cov khoom lag luam nce ntxiv hauv kev lag luam.
Tsis tas li ntawd, cov crucibles no muaj cov cua kub zoo heev thiab tuaj yeem tiv taus kub txog 1200 txog 1600 ° C.Qhov kev ua tau zoo tshwj xeeb no ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau qhov kub thiab txias, xws li hlau castings thiab foundries.Kev muaj peev xwm tiv taus qhov kub thiab txias yam tsis muaj kev cuam tshuam kev ua haujlwm yog qhov hloov pauv rau ntau yam kev lag luam.
Ib qho ntawm cov khoom zoo tshaj plaws ntawm cov graphite crucibles yog lawv cov corrosion kuj zoo heev.Lawv qhia tau zoo heev txawm nyob rau hauv lub ntsej muag ntawm corrosive molten cov ntaub ntawv, kom ntseeg tau lub neej ntev thiab txhim khu kev qha.Qhov kev tiv thaiv corrosion no nthuav dav ntau yam kev siv ntawm cov crucibles, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj thiab metallurgical industries.
Tsis tas li ntawd, nws superior thermal shock kuj ua rau nws superior rau cov khoom zoo sib xws.Graphite crucibles pom elasticity nyob rau hauv ceev ceev cua txias thiab cua sov voj voog, ua rau lawv tsis tshua muaj kev tawg thiab tawg.Qhov kev ua tau zoo tshaj plaws no tsis tsuas yog txhim kho kev nyab xeeb xwb tab sis kuj tseem muab kev txuag nqi tseem ceeb los ntawm kev txo qhov xav tau kev hloov pauv ntau zaus.
Graphite crucibles yog dav siv nyob rau hauv ntau yam lag luam vim lawv zoo heev thermal conductivity thiab kub tsis kam.Cov crucibles no muaj cov coefficient tsawg ntawm thermal expansion thiab resistant rau tam sim ntawd hloov nyob rau hauv kub.Lawv tuaj yeem tiv taus cua sov thiab txias sai yam tsis muaj kev cuam tshuam loj, ua kom pom kev ua haujlwm zoo thiab kev ntseeg siab.
Graphite crucibles muaj piv txwv corrosion tsis kam mus rau acidic thiab alkaline cov kev daws teeb meem, ua rau lawv tseem ceeb hauv cov chaw soj nstuam thiab cov chaw tsim tshuaj.Lawv cov kev ruaj ntseg zoo heev rau cov tshuaj tiv thaiv kab mob qhia tau tias lawv cov kav ntev thiab tuaj yeem ua rau muaj kev nyab xeeb ntawm ntau yam tshuaj.
Cov muaj pes tsawg leeg ntawm graphite crucible yog ntuj flake graphite ua cov khoom siv tseem ceeb.Nws tau tuav ua ke siv cov nplaum tshwj xeeb hu ua yas hluav taws kub charcoal.Qhov kev sib xyaw tshwj xeeb no ua kom ntseeg tau tias graphite crucibles tswj kev ua haujlwm ruaj khov nyob rau hauv cov xwm txheej hnyav, muab cov txiaj ntsig zoo sib xws hauv ntau yam kev siv.
Lub advent ntawm domestically tsim graphite crucibles tsis tsuas yog cim ib tug technologies breakthrough, tab sis kuj txhawb txoj kev loj hlob ntawm lub zos industries.Hauv zos tsim, zoo crucibles txo kev cia siab rau kev ntshuam thaum muab cov nqi sib tw rau ntau yam kev lag luam.Txoj kev loj hlob no ua rau txoj hauv kev kom muaj kev txaus siab rau tus kheej ntau dua thiab ntxiv dag zog rau lub teb chaws thaj chaw muaj kev lag luam.
Hauv cov ntsiab lus, kev tsim kho tshiab hauv graphite crucible ntau lawm tau thawb nws mus rau qhov siab tshiab, tshaj cov khoom lag luam zoo sib xws ntawm kev ua tau zoo thiab kav ntev.Zoo heev thermal conductivity, zoo heev kub tsis kam, corrosion kuj thiab thermal poob siab kuj ua rau nws invaluable nyob rau hauv ntau yam kev lag luam daim ntaub ntawv.Nrog rau cov kev nce qib no, kev lag luam hauv tsev graphite crucible tau ua rau muaj txiaj ntsig zoo rau lub teb chaws kev lag luam kev loj hlob thiab kev cia siab rau tus kheej.
