Graphite electrodes yog ib qho tseem ceeb ntawm kev siv ntau yam kev lag luam, tshwj xeeb tshaj yog nyob rau hauv steel manufacturing sector.Cov electrodes no ua lub luag haujlwm tseem ceeb hauv hluav taws xob arc rauv, uas lawv tau siv los tsim kom muaj qhov kub thiab txias uas xav tau rau melting thiab refining hlau.Txawm li cas los xij, qhov kev siv siab ntawm graphite electrodes tau muaj kev txhawj xeeb loj hlob hauv kev lag luam.
Yuav kom nkag siab tias yog vim li cas graphite electrode noj yog siab, ib tug yuav tsum xub xyuas qhov xwm ntawm lawv cov hauj lwm.Hluav taws xob arc rauv ua kom muaj cua sov los ntawm kev dhau ntawm hluav taws xob tam sim no los ntawm graphite electrodes, uas tsim cov hluav taws xob arc thaum lawv los ntawm cov khoom siv raw.Raws li qhov tshwm sim, cov electrodes raug kev ntxhov siab vim muaj cua sov, tshuaj lom neeg, thiab lub cev hnav thiab tsim kua muag.
Ib qho ntawm cov laj thawj tseem ceeb rau kev siv cov graphite electrode yog qhov nruam ntawm electrode yaig thaum lub sij hawm arc txheej txheem.Qhov kub kub ua rau cov graphite oxidize, ua rau cov pa roj carbon dioxide tsim.Cov tshuaj tiv thaiv no ua rau kev tawg ntawm cov khoom siv graphite thiab thaum kawg ua kom cov electrode noj.Tsis tas li ntawd, kev kub ntxhov thiab tshuaj lom neeg ua rau cov thermal thiab tshuaj lom neeg hnav ntawm cov electrodes, ntxiv rau lawv txoj kev yaig sai.
Lwm qhov tseem ceeb, qhov zoo ntawm graphite electrodes kuj cuam tshuam rau lawv tus nqi noj.Cov electrodes tsis zoo, nrog cov qib impurity siab dua lossis qis dua, yuav ua rau muaj qhov nrawm dua.Cov electrodes tej zaum yuav raug nqi pib tab sis ua rau muaj kev noj ntau ntxiv nyob rau lub sijhawm ntev.Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov khoom siv hluav taws xob zoo uas muaj kev tiv thaiv zoo dua rau cov cua sov thiab hnav, txo kev noj thiab txhim kho tag nrho cov txiaj ntsig.
Txographite electrodekev noj yuav tsum muaj kev sib xyaw ua ke ntawm kev kho kom raug thiab cov tswv yim tiv thaiv.Ua ntej, optimizing cov kev khiav hauj lwm tsis ntawm hluav taws xob arc furnaces yuav txo tau electrode noj.Los ntawm kev xaiv qhov tsim nyog electrode txoj kab uas hla, qhov ceev tam sim no, thiab kev khiav hauj lwm voltage, qhov hnav thiab kua muag ntawm cov electrodes tuaj yeem txo qis.Nws yog ib qho tseem ceeb kom nrhiav tau qhov sib npaug ntawm kev ua tiav cov khoom lag luam siab thiab txo cov electrode noj.
Tsis tas li ntawd, kev txhim kho qhov zoo thiab cov khoom ntawm graphite electrodes lawv tus kheej tuaj yeem pab txo kev noj.Cov neeg tsim khoom txuas ntxiv ua haujlwm ntawm kev txhim kho qib ntawm electrodes nrog kev txhim kho thermal thiab tshuaj tiv thaiv.Cov electrodes no tuaj yeem tiv taus qhov kub thiab txias thiab tshuaj lom neeg, txhim kho lawv lub neej ntev thiab txo qis degradation.Kev nqis peev hauv cov khoom siv hluav taws xob zoo yuav pib ua tus nqi siab dua tab sis tuaj yeem ua rau muaj txiaj ntsig zoo rau lub sijhawm ntev.
Kev saib xyuas zoo thiab kev tshuaj xyuas tsis tu ncua ntawm electrodes kuj tseem ceeb heev rau kev txo qis kev noj.Kev tshawb nrhiav thiab kho txhua qhov tsis xws luag, tawg, lossis kev puas tsuaj thaum lub sijhawm ua haujlwm ntawm lub tshuab hluav taws xob tuaj yeem tiv thaiv kev puas tsuaj ntxiv, yog li elongating lub neej ntawm cov electrodes.Tsim nyogelectrode tuav, khaws cia, thiab cov txheej txheem kev teeb tsa kuj tuaj yeem pab txo qis electrode hnav thiab noj.
Ua raws li cov thev naus laus zis thiab kev siv tshuab hluav taws xob hauv cov txheej txheem steel hlau kuj tseem tuaj yeem pab txo qis graphite electrode noj.Lub sijhawm saib xyuas lub sijhawm tiag tiag, kev tswj hwm tsis siv neeg, thiab kev txheeb xyuas cov ntaub ntawv tuaj yeem pab txhim kho cov haujlwm ntawm lub cub tawg thiab txo qis kev siv hluav taws xob.
Hauv kev xaus, kev siv siab ntawm graphite electrodes hauv kev tsim steel yog ib qho kev sib tw uas yuav tsum tau saib xyuas thiab ua haujlwm.Kev nkag siab txog cov laj thawj tom qab kev siv siab, xws li kev kub ntxhov, oxidation, thiab kev xav tau ntawm cov hlau ntau ntxiv, yog qhov tseem ceeb.Los ntawm kev siv cov tswv yim xws li kev ua kom zoo rau kev ua haujlwm tsis zoo, xaiv cov khoom siv hluav taws xob zoo, kev saib xyuas zoo, thiab siv cov thev naus laus zis siab, graphite electrode noj yuav txo tau zoo.Kev txo cov electrode noj tsis tsuas yog ua rau cov nqi txuag tab sis kuj ua rau muaj kev ruaj ntseg ib puag ncig los ntawm kev txo qis kev siv cov peev txheej ntuj.
