Cov yam ntxwv tseem ceeb ntawm peb cov Melting Crucibles

1. Crucible Materials:
   • Silicon Carbide Crucibles: Paub txog lawv cov thermal conductivity zoo heev, cov crucibles no tuaj yeem ua haujlwm tau zoo ntawm qhov kub thiab txias mus txog1700 ° C, deb tshaj qhov melting point ntawm txhuas (660.37 ° C). Lawv cov qauv high-density muab lub zog zoo kawg nkaus thiab ua haujlwm rau deformation.
   • Carbonized Silicon Carbide Crucibles: Ib qho kev txhim kho uas hais txog qhov tsis muaj zog uas muaj nyob rau hauv cov tsoos crucibles, xws li tsis muaj zog thiab tsis zoo thermal shock resistance. Cov crucibles no siv cov khoom sib xyaw ntawm carbon fiber thiab silicon carbide, ua kom muaj kev ua tau zoo dua.
2. Qhov zoo tshaj plaws Crucible Material:
   • Peb cov silicon carbide crucibles muaj cov yam ntxwv zoo, suav nrog:
     • Melting Point: Mus txog2700 ° C, haum rau ntau yam kev siv kub kub.
     • Qhov ntom: 3.21 g / cm³, pab txhawb rau lawv cov neeg kho tshuab muaj zog.
     • Thermal conductivity: 120 W/m·K, enabling ceev thiab niaj hnub cua sov faib rau kev txhim kho melting efficiency.
     • Thermal Expansion Coefficient: 4.0 × 10⁻⁶/°Cnyob rau hauv thaj tsam ntawm 20-1000 ° C, txo qis thermal stress.
3. Crucible Temperature Range:
   • Peb cov crucibles yog tsim los tiv thaiv kev khiav hauj lwm kub ntau ntawm800 ° C rau 2000 ° Cnrog ib qho instantaneous siab kub tsis kam ntawm2200 ° C, kom ntseeg tau tias muaj kev nyab xeeb thiab muaj txiaj ntsig melting ntawm ntau yam hlau.

Specifications (Customizable)

• Txo Thickness: Peb carbonized silicon carbide crucibles yog tsim los nrog ib tug tuab txo ntawm30%, txhim kho thermal conductivity thaum tuav lub zog.
• Ua kom muaj zog: Lub zog ntawm peb cov crucibles yog nce los ntawm50%, ua rau lawv tiv taus ntau dua mechanical stress.
• Thermal Shock Resistance: Txhim kho los ntawm40%, txo qhov yuav ua rau tawg thaum cua sov thiab cua txias.

Kev tsim khoom

Cov txheej txheem tsim khoom rau peb cov carbonized silicon carbide crucibles muaj ob peb kauj ruam tseem ceeb:

1. Preform Creation: Carbon fiber yog preprocessed rau hauv ib daim ntawv haum rau crucible ntau lawm.
2. Carbonization: Cov kauj ruam no tsim cov qauv ntawm silicon carbide thawj zaug.
3. Densification thiab Purification: Ntxiv carbonization tsub kom cov khoom ceev thiab tshuaj stability.
4. Siliconing: Lub crucible yog dipped rau hauv molten silicon los txhim kho nws lub zog thiab corrosion kuj.
5. Kawg Shaping: Lub crucible yog zoo li tus kom tau raws li cov kev cai tshwj xeeb, kom ntseeg tau tias kev ua tau zoo.

Qhov zoo thiab kev ua tau zoo

• Siab kub zog: Nrog lub peev xwm los tswj cov qauv kev ncaj ncees ntawm qhov kub thiab txias, peb cov silicon carbide crucibles ua kom muaj kev ntseeg siab thaum lub sij hawm kub melting txheej txheem.
• Corrosion Resistance: Cov crucibles no tiv thaiv corrosion los ntawm molten aluminium thiab lwm yam hlau, ua kom lawv lub neej ntev thiab txo qhov hloov zaus.
• Chemically Inert: Silicon carbide tsis hnov ​​​​mob nrog txhuas, ua kom cov purity ntawm cov hlau molten thiab tiv thaiv kev sib kis ntawm impurities.
• Mechanical Strength: Nrog lub zog khoov ntawm400-600 MPa, peb cov crucibles tuaj yeem tiv taus cov khoom hnyav, ua rau lawv tsim nyog rau kev thov.

Daim ntawv thov

Silicon carbide melting crucibles yog dav siv hauv:

• Aluminium Smelting Cog: Qhov tseem ceeb rau melting thiab purifying aluminium ingots, kom ntseeg tau cov khoom zoo aluminium.
• Aluminium Alloy Foundries: Muab kev ruaj khov kub-kub ib puag ncig rau cov casting ntawm aluminium alloy qhov chaw, txhim kho cov khoom zoo thiab txo cov nqi seem los ntawm30%.
• Laboratories thiab Research Institutions: Qhov zoo tshaj plaws rau kev sim ntsuas kub, ua kom cov ntaub ntawv raug thiab txhim khu kev qha vim lawv cov tshuaj inertness thiab thermal stability.
