Hauv cov hlau hlau casting kev lag luam, melting tooj liab yog qhov txheej txheem xav tau. Tooj liab lub ntsiab lus ntawm 1084 ° C uas yog cov qauv xav tau ntawm kev ua tau zoo ntawm cov khoom siv smelting, tshwj xeeb tshaj yog hais txog kev kub siab thiab kub hloov efficiency. Nrog nws cov khoom siv lub cev thiab tshuaj lom neeg zoo, silicon carbide graphite crucite tau dhau los ua tus tooj liab zoo thiab kev lag luam melting rau cov lag luam.
Vim li cas thiaj xaiv Silicon Carbide Graphite Crucible?
Sic graphite crucible tsis tsuas yog ua tau ntawm qhov kub kub yaj, tab sis kuj outperforms tsoos kev pab cuam lub neej, lub zog txuag thiab tu nqi. Cov hauv qab no yog cov ncauj lus kom ntxaws ntawm nws cov ntsiab lus tseem ceeb:
1. Siab thermal conductivity
Lub thermal conductivity ntawm silicon carbide graphite crucible yog qhov ntau dua li cov khoom siv dog dig, uas txhais tau tias:
Cov cua kub ceev: tuaj yeem hloov tau cua sov rau sab hauv ntawm crucible, txhim kho melting efficiency.
Lub Zog Txuag Nyiaj Txiag: Txo cov cua sov, txo roj lossis siv hluav taws xob, yog li txo cov nqi hluav taws xob.
2. Kev kub siab thiab sov sov tsis kam
Silicon carbide graphite cov khoom siv tuaj yeem tiv taus ntau qhov kub siab tshaj 1300 ° C, thaum muaj cov cua sov zoo heev:
Cua sov ruaj khov: nyob rau hauv tus txheej txheem rov ua dua siab kub yaj thiab txias, tsis yooj yim rau tawg lossis deformation.
Lub neej ntev: Wallt ntau cov kev hloov pauv hloov pauv, tshwj xeeb yog tsim nyog rau kev siv kev siv siab ntau lawm.
3. Zoo heev corrosion tsis kam
Thaum lub sij hawm tooj liab smelting, acidic lossis alkaline slag yuav tsim tawm, uas yuav ua rau corrosion rau tus ntoo khaub zig. Cov yam ntxwv ntawm silicon carbide graphite Crucible yog:
Tshuaj Yaig Yis Yaig Yeem: Nws tuaj yeem tiv thaiv Slag Intringement thiab tuav cov qauv kev ncaj ncees.
Siv sijhawm ntev dua: txo cov zaus ntawm kev hloov vim tias corrosion thiab txuag nqi rau cov lag luam.
4. Txuas Ntxiv Lub Neej
Piv nrog cov tsoos av nplaum-Graphite Crucible, kev pabcuam lub neej ntawm silicon carbide graphite crucite tuaj yeem txuas ntxiv los ntawm 20% -30%. Qhov no tsis tsuas yog txo cov zaus ntawm kev hloov, tab sis kuj tseem txo cov nqi txij nkawm.
Xaiv cov txiaj ntsig zoocrucibles rau melting tooj liab: Yuav ntsuam xyuas thiab xaiv li cas?
1. Txheeb xyuas qhov loj me thiab specifications
Xaiv cov crucible tsim nyog raws li kev tsim khoom kom ntseeg tau tias nws tuaj yeem ua kom tau raws li cov peev txheej ntawm cov khoom muaj peev xwm thiab tooj liab.
2. Tsom ntsoov rau cov thev naus laus zis
Tus crucible siv isostatic nias cov txheej txheem muaj ntau dua ntom ntom thiab cov zog tawg tawm, uas yog ib lub cim ntawm cov zoo crucible.
3. Cov khoom siv ua tau zoo
Nco ntsoov tias cov crucible siv siab-dawb huv silicon carbide thiab graphite cov ntaub ntawv los muab cov txiaj ntsig zoo tshaj melting.
4. Tom qab-muag kev pabcuam lav
Xaiv ib qho chaw muag khoom nrog cov kev pab cuam tom qab muag, xws li lub tuam txhab uas muab kev txhawb nqa kev siv tswv yim thiab hloov cov lus pom zoo.
Yuav ua li cas melting tooj liab nyob rau hauv ib tug crucible: ib tug tswv yim qhia
Txhawm rau muab kev ua si tag nrho rau kev ua yeeb yam ntawm silicon carbide graphite crucible, qhov tseeb siv txoj kev thiab kev txij nkawm yog qhov tseem ceeb heev. Ntawm no yog qee cov lus qhia tshaj lij:
1. Preheat kom zoo
Kev siv thawj zaug: Preheat cov crucible ntawm qhov tsawg ntawm xyoo 200 ° C-300 ° C rau 2 teev, thiab tom qab ntawd maj mam sawv mus ua haujlwm kub.
Kev siv txhua hnub: Zam kev txias heev thiab cua sov sai li sai tau txo qhov kev cuam tshuam ntawm thermal poob siab rau tus crucity.
2. Tswj lub suab kub yaj
Pom zoo qhov ntsuas kub: 11 ° C txog 1300 ° C kom ntseeg tau tias tus tooj liab tau yaj tag nrho vim muaj qhov kub tshaj plaws vim qhov kub dhau los.
3. Kev tu thiab khaws cia
Ua raws sij hawm tulag: Tom qab siv, tshem tawm cov npoo thiab sab hauv cov crucible kom ua kom nws cov kev ua tau zoo kawg nkaus.
Kev Cia Yuav Tsum: Tus crucule yuav tsum tau muab cia rau hauv ib puag ncig qhuav, cua kom tsis txhob muaj cov dej noo lossis kev puas tsuaj.
Xaiv tus nqi-ua tau zoo melting tooj liab cuppable crucible
Yog tias koj tab tom nrhiav rau lub nkuaj ruaj ruaj, txhim khu kev qha thiab kev ua tau zoo tshaj plaws ntawm cov pob zeb tooj liab, peb pom zoo kom cov silicon carbide graphite crucite los ntawm Rongda tuam txhab.
Qhov Zoo:
