Graphite electrodesua lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub no, tshwj xeeb tshaj yog nyob rau hauv thaj av ntawm steelmaking.Yog tsis muaj cov khoom tseem ceeb no, tag nrho cov txheej txheem steel yuav tuaj rau kev sib tsoo.Yog li ntawd, qhov kev thov rau high-zoo graphite electrode manufacturers tau skyrocketed nyob rau hauv xyoo tas los.
Graphite electrodes feem ntau yog siv nyob rau hauv hluav taws xob arc furnaces (EAFs) thiab ladle furnaces muab hluav taws xob rau melting seem hlau los yog lwm yam raw khoom.Cov electrodes no muab lub zog hluav taws xob tsim nyog los ua kom muaj cua sov loj uas yuav tsum tau yaj cov hlau thiab pib cov tshuaj tiv thaiv kom tshem tawm impurities los ntawm cov hlau molten.Nrog rau kev ua haujlwm tseem ceeb, kev xaiv ntawm cov chaw tsim khoom graphite electrode ua qhov tseem ceeb rau cov neeg tsim khoom steel.
Covgraphite electrodes txheej txheem ntau lawmpib nrog kev ua tib zoo xaiv cov khoom siv raw, feem ntau yog roj av coke thiab rab koob coke.Cov ntaub ntawv no dhau los ua cua sov kom tshem tawm cov impurities, uas ua rau cov khoom lag luam siab purity carbonaceous.Cov purified coke yog ces tov nrog thee tar suab thiab zoo li tus xav tau electrode zoo siv cov txheej txheem molding.Tom qab ntawd, cov khoom semi-tiav yog ci ntawm qhov kub siab heev los hloov nws mus rau hauv cov khoom siv carbon.Ntau qhov kev sib tw ntawm machining thiab kev soj ntsuam zoo ntxiv yog ua los xyuas kom cov electrodes ua tau raws li qhov yuav tsum tau ua.
Txawm li cas los xij, ua ib lub chaw tsim khoom graphite electrode tsis yog tsis muaj nws cov nyom.Ua ntej, kev lag luam ntsib kev txhawj xeeb txog ib puag ncig zoo vim yog cov pa roj carbon ntau ntawm cov txheej txheem tsim khoom.Paub txog qhov no, cov tuam txhab lag luam tau nqis peev hauv kev tshawb fawb thiab kev tsim kho kom txo lawv cov pa roj carbon hneev taw thiab txo qis kev tsim khoom pov tseg.Tsis tas li ntawd, qhov muaj thiab tus nqi ntawm cov khoom siv raw khoom zoo yog qhov tseem ceeb uas cuam tshuam rau kev tsim khoom.Txhua qhov kev cuam tshuam hauv cov khoom siv raw khoom tuaj yeem cuam tshuam loj rau kev tsim cov graphite electrodes.
Tshaj li kev lag luam steelmaking, graphite electrodes kuj pom daim ntawv thov hauv lwm cov haujlwm.Piv txwv li, lawv yog cov khoom tseem ceeb hauv hluav taws xob arc rauv siv rau melting seem txhuas.Qhov kev thov rau txhuas yog tsis tu ncua vim nws lub teeb yuag thiab kev siv dav hauv kev thauj mus los thiab kev tsim kho.Graphite electrode manufacturers ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ruaj ntseg ntawm cov electrodes kom tau raws li qhov kev xav tau loj hlob no.
Ntxiv mus, graphite electrodes yog indispensable nyob rau hauv zus tau tej cov silicon hlau thiab lwm yam silicon-raws li alloys.Silicon yog ib qho tseem ceeb hauv kev tsim khoom ntawm ntau yam khoom siv hluav taws xob, hnub ci vaj huam sib luag, thiab txawm tias cov khoom siv kho mob.Raws li thev naus laus zis nce qib thiab qhov kev thov rau cov khoom lag luam no nce siab, qhov tseem ceeb ntawm cov tuam txhab graphite electrode txhim khu kev qha tau tshwm sim ntau dua.
Hauv kev xaus,graphite electrode manufacturersyog cov neeg tseem ceeb hauv kev lag luam, nrog rau lawv cov khoom txhawb nqa ntau yam txheej txheem tseem ceeb.Lawv cov kws tshaj lij hauv kev tsim cov khoom siv hluav taws xob zoo tau lees paub qhov kev ua haujlwm du ntawm cov hluav taws xob arc rauv taws thiab cov ladle furnaces.Txawm hais tias muaj kev sib tw muaj feem cuam tshuam txog kev cuam tshuam ib puag ncig thiab cov khoom siv raw khoom, kev lag luam txuas ntxiv mus ntxiv, siv zog rau kev coj ua kom ruaj khov thiab cov thev naus laus zis tshiab.Raws li qhov kev thov rau steel, aluminium, thiab silicon-raws li alloys tseem nce ntxiv, kev koom tes ntawm graphite electrode manufacturers yog qhov tseem ceeb rau kev loj hlob thiab kev loj hlob ntawm cov sectors no.
