Lub thermal system ntawm ntsug ib leeg siv lead ua rauv kuj hu ua thermal field. Kev ua haujlwm ntawm graphite thermal teb system yog hais txog tag nrho cov txheej txheem rau melting silicon cov ntaub ntawv thiab ua kom cov siv lead ua ib qho kev loj hlob ntawm qhov kub thiab txias. Cias muab, nws yog ib tug tiavgraphite cua sov systemrau rub ib leeg siv lead ua silicon.
Lub graphite thermal teb feem ntau suav nrog(graphite khoom) siab nplhaib, rwb thaiv tsev cover, sab sauv, nruab nrab thiab qis rwb thaiv tsev cover,graphite crucible(peb-petal crucible), crucible txhawb pas nrig, crucible tais, electrode, rhaub,coj cev, graphite bolt, thiab txhawm rau tiv thaiv silicon to, lub cub tawg hauv qab, hlau electrode, kev txhawb nqa pas nrig, yog txhua yam nruab nrog cov ntawv tiv thaiv thiab cov npog tiv thaiv.
Muaj ntau ntau yam laj thawj rau kev siv graphite electrodes hauv thermal teb:
Zoo conductivity
Graphite muaj hluav taws xob zoo conductivity thiab muaj peev xwm ua tau zoo tam sim no hauv thermal teb. Thaum lub tshav kub ua haujlwm, lub zog tam sim no yuav tsum tau nkag los ntawm electrode los ua kom sov. Cov graphite electrode tuaj yeem ua kom ntseeg tau tias tam sim no dhau mus ruaj khov, txo lub zog poob, thiab ua rau lub tshav kub kub sai sai thiab ncav cuag qhov xav tau ua haujlwm kub. Koj tuaj yeem xav txog tias, ib yam li siv cov xaim zoo hauv ib lub voj voog, graphite electrodes tuaj yeem muab cov channel tsis muaj kev cuam tshuam rau lub tshav kub kom ntseeg tau tias kev ua haujlwm ib txwm muaj ntawm thermal teb.
Kub kub kuj
Cov thermal teb feem ntau ua haujlwm nyob rau hauv qhov chaw kub kub, thiab cov graphite electrode tuaj yeem tiv taus qhov kub thiab txias. Lub melting point ntawm graphite yog siab heev, feem ntau siab tshaj 3000 ℃, uas ua rau nws muaj kev ruaj ntseg qauv thiab kev ua tau zoo nyob rau hauv ib tug high-kub thermal teb, thiab yuav tsis soften, deform los yog yaj vim kub kub. Txawm tias nyob rau hauv lub sij hawm ntev kub kub ua hauj lwm tej yam kev mob, graphite electrode tuaj yeem ua haujlwm tau zoo thiab muab cov cua kub tsis tu ncua rau lub tshav kub.
Tshuaj stability
Graphite muaj cov tshuaj zoo ruaj khov ntawm qhov kub thiab txias thiab tsis yooj yim rau cov tshuaj lom neeg nrog rau lwm cov tshuaj hauv tshav kub. Nyob rau hauv lub tshav kub, tej zaum yuav muaj ntau yam gases, molten hlau los yog lwm yam tshuaj, thiab graphite electrode tuaj yeem tiv taus qhov yaig ntawm cov tshuaj no thiab tswj nws tus kheej kev ncaj ncees thiab kev ua haujlwm. Qhov kev ruaj ntseg tshuaj no ua kom muaj kev siv lub sij hawm ntev ntawm graphite electrodes hauv thermal teb thiab txo qhov kev puas tsuaj thiab hloov zaus ntawm electrodes tshwm sim los ntawm cov tshuaj tiv thaiv.
Mechanical zog
Graphite electrodes muaj qee yam kev siv zog thiab tuaj yeem tiv taus ntau yam kev ntxhov siab hauv tshav kub. Thaum lub sij hawm installation, siv thiab txij nkawm ntawm thermal teb, cov electrodes tej zaum yuav raug rau sab nraud quab yuam, xws li clamping quab yuam thaum lub sij hawm installation, kev nyuaj siab tshwm sim los ntawm thermal expansion, thiab lwm yam. Lub zog mechanical zog ntawm graphite electrode enables nws nyob ruaj khov nyob rau hauv no. kev ntxhov siab thiab tsis yooj yim tawg lossis puas.
Nqi-zoo
Los ntawm tus nqi saib, graphite electrodes yog tus nqi qis. Graphite yog ib qho khoom siv ntau yam nrog cov mining thiab cov nqi ua haujlwm tsawg. Nyob rau tib lub sijhawm, graphite electrodes muaj lub neej ua haujlwm ntev thiab txhim khu kev qha, txo tus nqi ntawm kev hloov electrode nquag. Yog li ntawd, kev siv graphite electrodes hauv thermal teb tuaj yeem txo cov nqi tsim khoom thaum ua kom muaj kev ua tau zoo.
