Hauv kev tshawb fawb txog metallurgy thiab cov khoom siv, cov khoom siv no tau siv dav. graphite crucibleyog ib qho cuab yeej tseem ceeb. Nws yog ib qho tseem ceeb rau cov txheej txheem uas xav tau kev yaj, kev pov tseg, lossis kev kho cua sov ntawm qhov kub siab heev. Tsis zoo li lwm cov ntaub ntawv, graphite muaj kev sib xyaw ua ke ntawm cov khoom siv thermal, tshuaj lom neeg, thiab lub cev uas ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau. Tsab xov xwm no yuav tshawb nrhiav vim li cas lub crucible graphite zoo yog lub hauv paus ntawm cov txheej txheem kev lag luam niaj hnub, los ntawm cov hlau muaj nqis casting mus rau kev tsim khoom semiconductor.

Vim li cas Graphite Crucible yog Qhov Kev Xaiv Zoo Tshaj Plaws rau Koj Lub Lag Luam

Kev xaiv cov khoom siv crucible zoo yog qhov kev txiav txim siab tseem ceeb uas cuam tshuam rau qhov zoo ntawm koj cov khoom kawg thiab kev ua haujlwm zoo. Nov yog vim li cas graphite thiaj li sawv tawm:

• Kev Tiv Thaiv Thermal Zoo Tshaj Plaws:Graphite tuaj yeem tiv taus qhov kub tshaj 3000 ° C (5432 ° F) hauv cov chaw tsis oxidizing. Qhov no ua rau nws zoo meej rau kev yaj ntau yam khoom siv, suav nrog kub, nyiaj, txhuas, thiab ntau yam alloys, yam tsis muaj deforming lossis tawg.
• Kev Ua Haujlwm Thermal Zoo Tshaj Plaws:Lub peev xwm zoo heev ntawm graphite los coj cua sov ua kom cov cua sov tau faib sib npaug thoob plaws hauv lub crucible, ua rau yaj sai dua thiab sib npaug dua. Qhov no tsis yog tsuas yog ua kom cov txheej txheem sai dua xwb tab sis kuj txo cov kev siv hluav taws xob.
• Kev Tsis Muaj Tshuaj Lom Zem:Graphite tiv taus cov tshuaj lom neeg los ntawm feem ntau cov hlau uas yaj thiab cov khoom siv corrosive. Qhov kev tsis sib haum xeeb no yog qhov tseem ceeb rau kev tswj hwm qhov huv ntawm cov khoom uas yaj, tiv thaiv kev ua qias tuaj uas yuav ua rau cov khoom kawg tsis zoo.
• Kev Nthuav Dav Thermal Tsawg:Ib qho tseem ceeb ntawm graphite yog nws cov coefficient qis ntawm thermal expansion. Qhov no txhais tau tias nws yuav tsis nthuav dav lossis cog lus ntau thaum cua sov thiab txias, tiv thaiv kev tawg thiab thermal shock uas feem ntau tshwm sim hauv lwm cov khoom siv crucible.
• Cov Khoom Uas Ua Rau Nws Tus Kheej Lubricating:Qhov lubricity ntuj ntawm graphite ua rau nws yooj yim rau kev tuav thiab pab tiv thaiv cov khoom molten los ntawm lo rau ntawm phab ntsa crucible, ua kom yooj yim rau cov txheej txheem casting thiab ntev lub neej ntawm crucible.

Cov Yam Tseem Ceeb Yuav Tsum Xav Txog Thaum Xaiv Graphite Crucible

Xaiv qhov yoggraphite crucibleyog qhov tseem ceeb rau koj daim ntawv thov tshwj xeeb. Ua tib zoo saib xyuas cov yam tseem ceeb no kom ntseeg tau tias koj tau txais kev ua tau zoo tshaj plaws.

1. Qib Graphite thiab Purity:
   • Qhov huv ntawm graphite yog qhov tseem ceeb rau cov ntawv thov uas muaj cov khoom siv huv siab. Nrhiav cov qib zoo li high-purity isostatic graphite rau semiconductor lossis cov hlau muaj nqis yaj.
   • Cov qib sib txawv muaj ntau qib ntawm qhov ceev, lub zog, thiab kev ua kom sov.
2. Qhov Loj thiab Duab:
   • Peev Xwm ntawm lub Crucible:Txheeb xyuas seb koj xav tau pes tsawg cov khoom siv los yaj. Nws yog ib qho tseem ceeb uas yuav tsum xaiv lub crucible uas muaj peev xwm tsim nyog kom phim koj qhov loj me.
