Graphite electrodes ua lub luag haujlwm tseem ceeb hauv ntau daim ntawv thov kev lag luam, feem ntau hauv cov hluav taws xob arc rauv qhov chaw uas lawv ua cov khoom siv hluav taws xob los pab txhawb kev smelting thiab refining ntawm hlau.Cov hluav taws xob conductivity ntawm graphite electrodes yog qhov tseem ceebgraphite electrode yam ntxwvuas cuam tshuam ncaj qha rau lawv cov kev ua tau zoo thiab kev ua haujlwm hauv cov txheej txheem no.
Dab tsi cuam tshuam rau graphite electrode hluav taws xob conductivity?
I: Purity thiab zoo ntawm graphite siv nyob rau hauv lawv cov khoom
High-zoo graphite nrog tsawg impurity theem, tshwj xeeb tshaj yog cov ntsiab lus sulfur, pom zoo hluav taws xob conductivity.Cov impurities nyob rau hauv graphite tuaj yeem cuam tshuam kev txav ntawm electrons, ua rau muaj kev tiv thaiv thiab txo cov hluav taws xob conductivity ntawm electrode.Yog li ntawd, cov neeg tsim khoom yuav tsum ua tib zoo xaiv thiab ua cov ntaub ntawv graphite kom ntseeg tau tias cov khoom siv hluav taws xob zoo.
II: Glos nag loj ntawm graphite hais siv nyob rau hauv lawv muaj pes tsawg leeg
Qhov loj me me ua rau muaj hluav taws xob ntau ntxiv vim qhov loj ntawm cov ntsiab lus sib txuas ntawm cov graphite hais.Qhov no ua kom yooj yim hloov ntawm cov hluav taws xob hla cov qauv electrode, yog li txhim kho hluav taws xob conductivity.Cov neeg tsim khoom feem ntau siv cov txheej txheem tshwj xeeb milling thiab sib tsoo kom ua tiav qhov xav tau ntawm cov nplej loj, yog li txhim kho electrode kev ua tau zoo.
III: ibomposition ntawm binder khoom siv nyob rau hauv zus tau tej cov graphite electrodes
Lub binder, feem ntau yog ib qho kev sib xyaw ntawm cov thee tar suab thiab roj av coke, ua raws li kev sib khi tus neeg sawv cev hauvelectrode manufacturing txheej txheem.Lub conductivity ntawm cov ntaub ntawv binder nws tus kheej tuaj yeem cuam tshuam tag nrho cov hluav taws xob conductivity ntawm electrode.Yog li, xaiv cov khoom siv nrog cov khoom siv hluav taws xob siab yog qhov tseem ceeb kom ntseeg tau tias kev ua haujlwm zoo ntawm graphite electrode.
IV: Density thiab porosity ntawm graphite electrode
Cov khoom siv hluav taws xob ntau dua, ua tiav los ntawm kev cog lus kom raug thaum lub sijhawm tsim khoom, txhim kho hluav taws xob conductivity los ntawm kev txo cov voids lossis pores.Cov voids no ua obstacles rau qhov ntws ntawm cov nqi hluav taws xob, nce kev tiv thaiv thiab cuam tshuam conductivity.Yog li ntawd, tswj kom haum electrode ceev thiab minimizing porosity yog ib qho tseem ceeb rau maximizing hluav taws xob conductivity.
V: Structural kev ncaj ncees ntawm graphite electrode
Hauv cov ntawv thov kev lag luam uas muaj cov dej ntws siab thiab kev ua haujlwm hnyav, cov thermal shock tsis kam ntawm graphite electrodes ua qhov tseem ceeb.Raws li hluav taws xob conductivity yog ze ze rau cov qauv kev ncaj ncees ntawm cov electrode, tej thermal tawg los yog puas yuav cuam tshuam rau conductivity.Yog li ntawd, cov tuam txhab lag luam tsom mus rau kev tsim cov graphite electrodes nrog cov thermal poob siab los xyuas kom ruaj khov hluav taws xob conductivity thaum ua haujlwm.
VI: Surface tiav ntawm graphite electrodes
Ib tug du nto tiav tso cai rau kev sib cuag hluav taws xob zoo dua thiab txo qhov kev sib cuag ntawm cov electrode thiab cov khoom siv tam sim no.Ntau yam kev kho deg, xws li coatings thiab polishing, yog ua hauj lwm los txhim kho cov khoom nto ntawm graphite electrodes, yog li txhim kho lawv cov hluav taws xob conductivity.
Nws yog ib qho tseem ceeb kom nco ntsoov tias hluav taws xob conductivity ib leeg tsis txiav txim siab tag nrho cov kev ua tau zoo ntawmgraphite electrodes.Lwm yam, xws li lub zog txhua yam, oxidation tsis kam, thiab tshuaj lom neeg ruaj khov, kuj tseem ua rau lawv cov txiaj ntsig zoo hauv kev lag luam.Yog li ntawd, kev nkag siab zoo ntawm txhua yam no yog qhov tseem ceeb hauv kev xaiv thiab siv graphite electrodes rau cov txheej txheem tshwj xeeb thiab kev lag luam.
TNws cov hluav taws xob conductivity ntawm graphite electrodes yog cov yam ntxwv tseem ceeb uas cuam tshuam ncaj qha rau lawv cov kev ua tau zoo hauv cov ntawv thov kev lag luam.Kev nkag siab thiab tswj cov yam tseem ceeb no yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm electrode thiab ua kom muaj kev ua haujlwm zoo thiab txhim khu kev qha hauv hluav taws xob arc furnaces thiab lwm yam txheej txheem zoo sib xws.
