Graphite electrodes, feem ntau hu ua graphite rods, ua lub luag haujlwm tseem ceeb hauv ntau yam lag luam vimgraphite electrodes zogthiab ntau yam kev siv.
I: Graphite electrodes feem ntau yog siv nyob rau hauv hluav taws xob arc rauv (EAFs) rau steel ntau lawm.
EAFs tau hloov pauv txoj hauv kev ib txwm muaj vim lawv qhov ua tau zoo thiab kev cuam tshuam ib puag ncig qis.Graphite electrodes ua raws li cov khoom siv hluav taws xob, tso cai rau kev hloov pauv ntawm hluav taws xob hluav taws xob mus rau hauv cov cua kub hnyav los ntawm hluav taws xob arc.Cov cua sov no yog siv los yaj cov hlau thiab tsim cov hlau zoo nkauj, tuav, thiab lwm yam khoom siv hlau.
II: Lwm qhov tseem ceeb ntawm graphite electrodes yog nyob rau hauv kev tsim cov hlau cam khwb cia.
Hauv cov txheej txheem zoo sib xws rau steelmaking, graphite electrodes tsim cov cua sov tsim nyog los yaj hlau thiab tshem tawm impurities.Tom qab ntawd cov hlau molten yog muab pov rau hauv ntau yam duab, xws li cov kav dej, daim hlau, thiab cov khoom siv tshuab.Graphite electrodes pab tswj qhov kub thiab txias, ua kom cov hlau cam khwb cia nrog cov yam ntxwv thiab cov khoom xav tau.
III: Graphite electrodes kuj tseem siv dav hauv kev tsim cov hlau silicon thiab ferroalloys.
Silicon hlau, yog ib qho tseem ceeb hauv kev tsim cov khoom siv hluav taws xob thiab cov hnub ci, yog tsim los ntawm cov txheej txheem txo carbothermic.Cov txheej txheem no suav nrog cov tshuaj tiv thaiv ntawm quartz nrog carbon ntawm qhov kub thiab txias.Graphite electrodesmuab cov cua sov tsim nyog los pab txhawb qhov kev tshwm sim no, uas ua rau cov khoom siv high-purity silicon hlau.
IV: Kev tsim cov ferroalloys, xws li ferrosilicon thiab ferrochrome, tso siab rau graphite electrodes rau lawv cov txheej txheem kub.
Ferroalloys yog qhov tseem ceeb hauv kev lag luam steel vim lawv muab cov khoom tshwj xeeb xws li hardness thiab corrosion tsis kam rau hlau.Graphite electrodes pab kom fusion ntawm ntau yam hlau ore nrog carbon, tsim ferroalloys uas ua tau raws li cov kev cai alloying.
V: Graphite electrodes nrhiav kev siv hauv kev tsim cov txhuas.
Hauv cov txheej txheem Hall-Héroult, txhuas yog muab rho tawm los ntawm alumina ore los ntawm electrolysis.Graphite electrodes ua raws li cathodes hauv cov txheej txheem no,ua hluav taws xobthiab pab txo qis ntawm alumina rau hauv aluminium.Qhov no ua kom muaj kev lag luam txuas ntxiv ntawm txhuas, ua graphite electrodes tseem ceeb rau kev lag luam txhuas.
VI: Graphite electrodes kuj tau ua haujlwm hauv kev lag luam electrochemical rau cov txheej txheem xws li electrorefining thiab electrowinning.
Electrorefining yog siv los ntxuav cov hlau tsis huv los ntawm electroplating, thaum electrowinning yog ua haujlwm los rho tawm cov hlau los ntawm ore.Graphite electrodes muab qhov tsim nyog hluav taws xob conductivity rau cov txheej txheem no, ua kom muaj kev sib cais, huv si, thiab rho tawm ntawm ntau yam hlau.
VII: Graphite electrodes yog siv rau hauv kev tsim cov roj teeb, tshwj xeeb tshaj yog lithium-ion roj teeb.
Graphite yog ib qho tseem ceeb ntawm cov anode nyob rau hauv lithium-ion roj teeb, uas nws khaws thiab tso tawm lithium ions thaum lub sij hawm them thiab tawm mus.Kev ua tau zoo thiab kev ua haujlwm ntawm cov roj teeb lithium-ion hnyav heev nyob ntawm qhov zoo thiab muaj pes tsawg leeg ntawm graphite electrodes siv.
VIII: Graphite electrodes yog siv hauv kev lag luam iav.
Iav melting furnaces yuav tsum tau kub siab los hloov cov ntaub ntawv raw rau hauv molten iav.Graphite electrodes ua lub luag haujlwm tseem ceeb hauv kev muab cov cua sov tsim nyog rau txoj haujlwm no.Lawv muaj peev xwm tiv taus qhov kub thiab txias thiab hluav taws xob siab ua rau lawv zoo tagnrho rau cov iav melting.
IX: Graphite electrodes feem ntau siv hauv EDM (Electrical Discharge Machining) txheej txheem.
Hauv EDM, kev tswj hluav taws xob tawm ntawm lub tshuab hluav taws xob thiab lub tshuab ua haujlwm tshem tawm cov khoom siv los ntawm cov khoom ua haujlwm, tso cai rau cov duab sib txawv thiab meej tsim.Graphite electrodes, nrog rau lawv cov thermal conductivity zoo heev thiab hluav taws xob tsis kam, ua kom muaj txiaj ntsig zoo thiab raug EDM cov haujlwm.
Hauv kev xaus, graphite electrodes muaj ntau yam kev siv thoob plaws ntau yam kev lag luam.Los ntawm cov hlau thiab hlau ntau lawm rau kev tsim cov roj teeb thiab iav, graphite electrodes yog qhov tseem ceeb rau kev ua kom cov txheej txheem kub kub thiab ua kom ntseeg tau qhov zoo thiab ua haujlwm ntawm cov khoom kawg.Lawv cov khoom tshwj xeeb ua rau lawv yog ib qho tseem ceeb ntawm cov txheej txheem kev lag luam ntau, ua rau kev txhim kho thev naus laus zis thiab kev txhim kho kom ruaj khov hauv ntau yam haujlwm.
