To taub cov sib txawv ntawm cov av nplaum graphles crucas thiab graphite silicon carbide crucailes

Thaum ua cov tshuaj xav ntsuas kub nyhav lossis cov ntawv thov kev lag luam, qhov kev xaiv ntawm cov kab txaij Crays lav txoj haujlwm tseem ceeb hauv kev ua tiav thiab kev nyab xeeb ntawm cov txheej txheem. Ob hom kev siv sib tsoo yogAv nplaum Grucite cruclesthiabGraphite silicon carbide crucailesCov. Nkag siab nws cov khoom siv, tshuaj lom neeg ua haujlwm, thiab thermal conductivity yog qhov tseem ceeb rau kev txiav txim siab thaum xaiv cov crucible tshwj xeeb rau kev kuaj tshwj xeeb lossis kev xaiv tau.

Cov khoom siv:
Avy graphite crucable crucible yog mas muaj ntawm graphite, av nplaum thiab qee qhov nyiaj ntawm cov roj nplua nyeem, thiab yog paub rau nws cov tshuaj lom neeg ua haujlwm. Ntawm qhov tod tes, graphite silicon carbide crucible yog ua los ntawm silicon carbide hmoov, thiab muaj cov yam ntxwv tsis tshua muaj cua sov tsis kam, thiab muaj cov tshuaj inertness.

Hluav Taws Kub Kub:
Cov refractory qhov kub ntawm cov tawv ntoo grucite feem ntau tau txog 1200 ° C, thaum lub sij hawm graphite sicibles tuaj yeem tiv thaiv kub siab dua 1500 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C.00 ° C. Qhov no ua rau graphite silicon carride crucailes ntau haum rau cov ntawv thov kom muaj qhov ntsuas siab dua hauv cov kev sim tshuaj thiab kev muaj cov txheej txheem.

Chemically inert:
Ob hom cruciles nthuav tawm cov kev ntsuas tshuaj lom neeg, seem nyob rau hauv feem ntau acid, alkali, thiab resistant rau corrosion. Txawm li cas los xij, cov av nkos tiv thaiv hauv av nplaum grucite ua rau nws nqus tau yooj yim dua thiab tsis yooj yim piv rau graphite siliciide crucailes.

Thermal Condivity:
Graphite muaj siab thermal conductivity thiab tuaj yeem dissipate kub sai. Txawm li cas los xij, vim txoj kev tsim nyog ntawm cov av nplaum graphite Crucite Crucite Crucible, cov pob dub yog nquag tshwm sim ntawm nws qhov chaw thiab yuav tsum tau tu. Hauv kev sib piv, graphite silicon carbide crucaile muaj qhov qis dua thermal conductivity thiab yuav tsis tawm stains rau saum npoo. Tsis tas li ntawd, lawv lub siab tawv tiv thaiv hnav thiab deformation.

Xaiv cov ntoo khaub lig zoo:
Thaum xaiv tshuaj lom neeg lub chaw kuaj tshuaj Crucible, cov cai tshwj xeeb yuav tsum raug txiav txim siab. Cov av nplaum grucite yog tsim nyog rau kev ntsuas cov pa roj hmab, thaum lub sij hawm scricon carbide crucaint yog qhov zoo rau cov kev sim kom koj xav tau cov xwm txheej ntau dua. Nws yog ib qho tseem ceeb kom ua raws li cov lus qhia rau siv kom tsis txhob sim sim vim tsis muaj kev ua haujlwm tsis raug cai.

Hauv cov ntsiab lus, nkag siab txog qhov sib txawv ntawm cov av nplaum gragples thiab graphite siciid ci yog qhov tseem ceeb rau kev xaiv cov ntoo khaub ncaws tshwj xeeb tshaj plaws lossis kev thov kev lag luam. Los ntawm kev xav txog yam xws li kev siv tshuaj kub, tshuaj lom neeg ua haujlwm thiab cov kws tshawb fawb thiab cov kws tshawb fawb tuaj yeem paub txog kev ua tiav thiab kev nyab xeeb ntawm kev sim thiab kev sim thiab cov txheej txheem.
