Qhov kev taw qhia no yuav tshawb txog cov yam ntxwv, qhov tshwj xeeb, thiab qhov zoo ntawm peb Crucible Rau Foundry thiab Crucible Rau Hlau Melting, kom ntseeg tau tias koj txiav txim siab paub txog koj txoj haujlwm.

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 zoo ntawm qhov kub txog 1700 ° 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 pom muaj nyob hauv cov khoom siv ib txwm muaj, xws li tsis muaj zog thiab tsis zoo thermal poob siab. 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 txog 2700 ° C, haum rau ntau yam kev siv kub.
     • Qhov ceev: 3.21 g / cm³, pab txhawb rau lawv lub zog txhua yam.
     • Thermal Conductivity: 120 W / m·K, ua kom ceev ceev thiab cov cua sov faib rau kev txhim kho melting efficiency.
     • Thermal Expansion Coefficient: 4.0 × 10⁻⁶ / ° C nyob 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 ntawm 800 ° C mus rau 2000 ° C nrog lub siab tshaj plaws kub tsis kam ntawm 2200 ° C, ua kom muaj kev nyab xeeb thiab muaj txiaj ntsig zoo ntawm ntau yam hlau.

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. Final 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

• High-Temperature Strength: Nrog lub peev xwm los tswj cov txheej txheem 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 kis kab mob los ntawm impurities.
• Mechanical Strength: Nrog lub zog khoov ntawm 400-600 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 Nroj Tsuag: Qhov tseem ceeb rau melting thiab purifying aluminium ingots, kom ntseeg tau cov khoom zoo txhuas.
• Aluminium Alloy Foundries: Muab qhov chaw ruaj khov rau qhov kub thiab txias rau cov khoom siv aluminium alloy, txhim kho cov khoom zoo thiab txo cov nqi seem ntawm 30%.
• 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.
