Hauv hluav taws xob arc rauv steelmaking, dag graphite electrodes ua lub luag haujlwm tseem ceeb hauv kev hloov pauv ntawm cov seem lossis ncaj qha txo cov hlau rau hauv cov kua hlau.Cov electrodes yog siv los ua hluav taws xob thiab tsim kom muaj qhov kub thiab txias uas yuav tsum tau yaj cov ntaub ntawv raw.Vim lawv cov thermal conductivity thiab tsis tshua muaj hluav taws xob tsis kam, cov khoom siv hluav taws xob graphite muaj peev xwm tiv taus cov xwm txheej huab cua hauv qhov cub, ua rau lawv xaiv qhov zoo tshaj plaws rau daim ntawv thov no.Tsis tas li ntawd, lawv lub zog tshwj xeeb ntawm kev siv tshuab thiab kev ua haujlwm rau thermal shock ua kom lub neej ntev dua, yog li txo cov nqi kho thiab hloov pauv.
Sib nrug los ntawm steelmaking, dag graphite electrodes kuj tau siv nyob rau hauv non-ferrous metallurgy, tshwj xeeb tshaj yog nyob rau hauv txhuas ntau lawm.Thaum lub sij hawm smelting txheej txheem, cov electrodes yog ua hauj lwm los muab lub zog tsim nyog rau lub electrolytic txo ntawm alumina rau hauv txhuas.Lub peev xwm nqa tam sim no siab thiab ua haujlwm zoo heev ntawm cov khoom siv hluav taws xob graphite ua rau lawv ua tau zoo rau daim ntawv thov no, ua kom muaj txiaj ntsig zoo thiab raug nqi txhuas.
Ntxiv mus, cov khoom siv hluav taws xob graphite pom kev siv dav hauv kev tsim cov tshuaj thiab cov khoom siv.Piv txwv li, lawv tau ua haujlwm hauv kev tsim khoomgraphite khoom, silicon hlau, thiab phosphorus, thiab lwm yam.Qhov zoo tshaj plaws hluav taws xob conductivity thiab thermal stability ntawm cov electrodes ua rau lawv xaiv rau cov txheej txheem uas muaj kev kub ntxhov siab thiab tiam ntawm cov cua kub ntau.Qhov no, nyob rau hauv lem, contributes rau enhanced productivity thiab zoo nyob rau hauv zus tau tej cov ntau yam tshuaj compounds thiab cov ntaub ntawv.
Ntxiv rau lawv cov ntawv thov sib txawv, cov khoom siv hluav taws xob graphite tau txais kev pom zoo rau lawv txoj kev ruaj khov thiab ib puag ncig cov txiaj ntsig.Raws li lub ntsiab lus tseem ceeb hauv hluav taws xob arc rauv steelmaking, cov electrodes no ua rau muaj txiaj ntsig zoo ntawm cov khoom siv hlau, yog li txo qhov kev thov rau cov khoom siv raw thiab ib puag ncig cuam tshuam nrog lawv cov extraction thiab ua.Tsis tas li ntawd, lawv siv nyob rau hauv non-ferrous metallurgy txhawb kev tsim ntawm lub teeb yuag thiab corrosion-resistant aluminium, uas muaj ntau daim ntawv thov nyob rau hauv lub tsheb, aerospace, thiab kev tsim kho kev lag luam, ua rau kom muaj kev ruaj ntseg thiab eco-phooj ywg.
Artificial graphite electrodes daim ntawv thovtsis txwv rau cov txheej txheem loj hauv kev lag luam tab sis tseem txuas ntxiv mus rau kev tshawb fawb thiab kev txhim kho hauv kev lag luam electrochemistry.Cov electrodes no yog siv nyob rau hauv kev sim thwmsim thiab pilot-scale kev tshawb fawb los soj ntsuam electrochemical tshua, electrocatalysis, thiab lub zog cia khoom.Lawv cov purity siab, uniformity, thiab tswj cov khoom ua rau lawv yog ib qho kev xaiv zoo tshaj plaws rau cov ntawv thov no, ua kom muaj tseeb thiab txhim khu kev qha hauv ntau yam kev tshawb fawb electrochemical.
Tsis tas li ntawd, kev siv ntau yam ntawm cov khoom siv hluav taws xob graphite ua rau lawv siv rau hauv lwm yam kev siv niche, xws li hluav taws xob arc teeb, tiv thaiv cua sov, thiab nuclear reactors.Nyob rau hauv hluav taws xob arc teeb, cov electrodes yog siv los tsim lub teeb khaus rau tshwj xeeb kev lag luam thiab kev tshawb fawb lub hom phiaj, thaum lub sij hawm nyob rau hauv tsis kam cua sov ntsiab, lawv muab tau cua sov nyob rau hauv high-temperature industrial processes.Tsis tas li ntawd, lawv siv nyob rau hauv nuclear reactors qhia tau hais tias lawv muaj peev xwm tiv taus huab cua kub thiab kub tej yam kev mob, ua rau lawv ib tug indispensable tivthaiv nyob rau hauv nuclear zog tiam.
Artificial graphite electrodes ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam, xws li steelmaking thiab non-ferrous metallurgy mus rau kev tsim cov tshuaj thiab cov khoom siv.Cov khoom cuavgraphite electrode zog, nrog rau cov thermal conductivity siab, txhua yam muaj zog, thiab tsis kam mus rau thermal shock, ua rau lawv xaiv zoo tshaj plaws rau cov ntawv thov uas muaj qhov kub thiab txias thiab lub zog hnyav.Tsis tas li ntawd, lawv cov sustainability, ib puag ncig cov txiaj ntsig, thiab ntau yam ntxiv qhia txog lawv qhov tseem ceeb hauv kev lag luam niaj hnub thiab kev tshawb fawb.Raws li kev siv thev naus laus zis thiab kev siv tshiab tau pom, cov khoom siv hluav taws xob graphite tau npaj los txuas ntxiv rau kev txhim kho thiab kev ua kom zoo ntawm ntau yam txheej txheem thoob plaws kev lag luam sib txawv.
