Yuav ua li cas ua crucibles

Raws li cov cuab yeej tseem ceeb hauv kev siv thev naus laus zis tam sim no,Silicon Carbide Crucibletau maj mam dhau los ua cov thawv uas tsis nyiam rau cov neeg tsis yog cov hlau smelting vim nws qhov kev ua tau zoo thiab cov khoom siv tshwj xeeb. Tshwj xeeb tshaj yog thaum ua cov khoom siv kub-kub yaj, silicon carbide crucailes pom kev pom kev zoo ntawm cov txiaj ntsig zoo. Kab lus no yuav qhia tau raws li kev ua kom cov yam ntxwv ntawm silicon carmigles crucailes, thiab yuav ua li cas muab cov kev daws teeb meem rau niaj hnub no caming tuam txhab.

1. Dab tsi yog Silicon Carbide Crucible?
Silicon carbide crucible yog qhov ntsuas kub uas siv cov khoom lag luam silicon carmide (sic) raws li cov khoom siv tseem ceeb. Nws yog tsuas yog siv rau smelting thiab ua ntau yam hlau thiab alloys. Silicon carbide yog cov khoom siv hluavtaws nrog cov khoom siv hluav taws xob tsis tshua muaj zog thiab kub tsis kam. Nws yog dav siv nyob rau hauv High-tech liaj xws li ceramics, metallurgy, thiab semiconductors.

Vim tias Silicon carbide crucailes muaj cov khoom siv lub cev thiab tshuaj lom neeg tsis muaj zog, lawv ua rau muaj kev ruaj khov tsis sib haum xeeb thiab tsis muaj kev cuam tshuam nrog qhov kub thiab txias.

2. Kev Tsim Kho ntawm Silicon Carbide Crucible
1. Cov kev kub siab kuj tsis kam
Silicon carride crucailes muaj cov kub kub tsis kam thiab tuaj yeem tiv taus kub tshaj 1600 ° C. Qhov no ua rau lawv zoo tagnrho rau smelting high-kub tshua xws li tooj liab, txhuas thiab npib tsib xee. Piv nrog cov crucibles ua los ntawm lwm cov ntaub ntawv, lub zog ntawm silicon carbide crucailes tsis txo qis hauv cov kev mob siab, ua kom nws cov duab ruaj khov thaum lub sijhawm smelting.

Qhov no zoo tshaj plaws-kub tsis kam pab cov tuam txhab kom tsis txhob muaj kev sib tsoo lossis tawg vim yog qhov kub siab, yog li kev ua tau zoo ntxiv.

2. Zoo thermal thermal
Lwm qhov kev ua tau zoo tshaj plaws ntawm Silicon Cov Khoom Siv Carmide yog nws lub siab thermal conductivity, uas tso cai rau kev ceev thiab txawm tias cua sov. Qhov no txhais tau tias thaum lub sij hawm smelting, lub molten hlau tuaj yeem ncav cuag qhov ntsuas kub kom ncav cuag, txo lub sijhawm thiab txhim kho ntau dua.

Qhov kev sib tsoo kub ua tau zoo kuj txo qis ntawm cov hlau molten, pab kom ua kom tiav qhov kev tswj kom sov ntau dua thaum lub sij hawm casting txheej txheem thiab ua kom muaj kev ua tau zoo.

3. Tsawg Thermal nthuav tawm coefficient
Cov coefficient ntawm thermal expansion hais txog qhov uas cov khoom nthuav dav hauv ntim thaum ua kom sov. Silicon carbide muaj qhov qis heev coefficient ntawm thermal nthuav, uas txhais tau tias nws hloov me me nyob rau hauv loj me me thaum rhuab. Yog li ntawd, txawm tias nyob hauv ib puag ncig nrog cov hloov pauv hnyav, lub cev ua si silbide crucible tuaj yeem tswj hwm nws cov qauv qub thiab kev puas tsuaj vim kev nthuav dav lossis kev sib zog.

Qhov kev nthuav dav tsawg yog qhov tshwj xeeb yog tsim nyog rau cov txheej txheem ua kom muaj kev cuam tshuam nrog cua sov thiab cua txias ntau ntxiv rau lub neej ntawm Crucible.

4. Zoo heev corrosion tsis kam
Thaum lub sij hawm smelting txheej txheem, cov hlau molten hlau reacts nrog tus ntoo khaub zig crucible, maj mam zuj zus nws cov nplaim dej. Txawm li cas los xij, Silicon Cov Khoom Siv Carbide muaj cov tshuaj lom zoo heev thiab muaj peev xwm tiv taus cov kua dej hlau, tshwj xeeb tshaj yog thaum ua rau cov hlau hluav taws xob ntau xws li tooj liab thiab txhuas.

Zoo corrosion tsis kam tsuas yog ncua kev pabcuam lub neej ntawm Crucible, tab sis kuj tseem yuav ua kom muaj kuab lom ntoo ntawm cov kua ntoo thiab txhim kho qhov zoo ntawm cov khoom kawg.

5. Muaj Zog Txhua Yam
Silicon carride crucaile tswj kom muaj kev kub kho tshuab hluav taws xob txawm tias muaj tsawg dua lossis tsis zoo. Qhov kev ua kom lub zog high-zog ua rau tus ntoo plig uas tau tiv thaiv kev cuam tshuam ntawm Molten hlau thiab kev tswj hwm cov txheej txheem sab nraud thaum lub sijhawm kub ntxhov.

6. Zoo thermal poob siab ruaj khov
Thermal poob siab loj hais txog lub peev xwm ntawm cov khoom siv kom tiv thaiv tawg thaum qhov ntsuas kub hloov sai. Silicon carride crucaintit ua kom pom zoo heev thermal poob peev thiab muaj peev xwm tiv thaiv kub kub hloov yam tsis muaj kev tawg. Qhov no yog qhov tshwj xeeb tshaj yog rau kev ua pov cov txheej txheem uas xav tau cua sov thiab cua txias.

peb. Daim Ntawv Thov ntawm Silicon Carbide Crucible
Vim nws qhov kev ua tau zoo tshaj plaws, thermal distances, silicon carbide crucai thiab casting cov txheej txheem, tshwj xeeb tshaj yog nyob rau hauv cov tsis-ferrous hlau thiab alloys. Cov hauv qab no yog ntau yam kev thov kev pabcuam:

Tooj liab CASTING: thaum smelting tooj liab,Silicon Carbide CrucibleS tuaj yeem ua kom cov khaub ncaws yaj hnyav, txo qhov kev tsim ntawm impurities, thiab txhim kho qhov zoo ntawm tooj liab qhov chaw.
Aluminium thiab Aluminium Alloy SMELTING: Aluminium yooj yim nti nrog cov crucuity ntawm silicing cov txheej txheem ntawm txhuas corrosion thiab ncua nws lub neej pabcuam.
Lwm qhov kev kub siab smelting: silicon carbide crucible kuj yog tsim nyog rau smelting heal metrals xws li zinc thiab npib tsib xee, thiab muaj qhov yoog tau.

Plaub. Siv thiab saib ntawm silicon carbide crucible
Txhawm rau txuas txoj kev pabcuam lub neej ntawm silicon carbide crucaid, siv tau thiab saib xyuas yog qhov tseem ceeb heev. Nov yog qee cov lus qhia:

Preheat cov crucible: ua ntej siv lossis rov siv dua, nws raug nquahu kom maj mam ua kom muaj cua sov thiab kub npau taws.
Zam kev kub ceev thiab cua txias: Txawm hais tias Silicon carbide crucaile muaj zoo thermal poob siab, nrawm nrawm hloov tseem yuav puas kev puas tsuaj rau tus ntoo khaub lig.
Kev soj ntsuam tsis tu ncua: Thaum siv, saib xyuas cov plaub hau crucible rau cov cim ntawm cov kab nrib pleb lossis xeb, thiab daws cov teeb meem muaj peev xwm ua tau raws sijhawm.
