Graphite electrodes pom kev siv dav hauv kev lag luam steel, uas lawv tau siv hauv hluav taws xob arc furnaces (EAF) rau steel ntau lawm.Hauv EAF,graphite electrodesyog ua hauj lwm los nqa cov hluav taws xob siab, uas tsim kom muaj cua sov tsim nyog rau melting seem steel thiab hloov mus rau hauv cov kua hlau.Cov xwm txheej zoo heev ntawm graphite tso cai rau nws los tiv thaiv cov cua sov uas ua rau lub sijhawm ua haujlwm no.
Graphite electrodes muaj cov txiaj ntsig zoo raws li hauv qab no:
High thermal thiab hluav taws xob conductivity:
Cov cuab yeej no ua rau lawv tiv taus qhov kub thiab txias thiab nqa hluav taws xob ntau yam tsis muaj qhov cuam tshuam loj.Cov electrodes ua lub luag haujlwm tseem ceeb hauv kev hloov pauv ntawm lub zog, uas ua rau muaj kev tsim khoom ntau dua thiab siv hluav taws xob qis dua.
Zoo heev mechanical zog thiab tsis kam rau thermal shock:
Cov khoom no ua rau lawv muaj zog heev thiab muaj peev xwm ua rau muaj kev xav tau nyob rau hauv lub tshuab hluav taws xob arc.Lub peev xwm los tiv thaiv thermal shock xyuas kom cov electrodes tsis tawg los yog tawg thaum lub sij hawm steelmaking txheej txheem, ua rau lub neej ntev thiab txo cov khoom downtime.
Tsawg coefficient ntawm thermal expansion:
Cov yam ntxwv no tso cai rau lawv nthuav dav thiab sib cog lus sib npaug thaum raug qhov kub thiab txias, txo qhov yuav ua rau tawg lossis tawg.Kev ruaj ntseg muab los ntawm graphite electrodes ua kom muaj kev ua tau zoo ib yam thiab ua rau cov tuam txhab hlau ua kom tiav kev tswj hwm tag nrho cov txheej txheem melting.
Tshuaj tiv thaiv:
Qhov no ua rau lawv siv tau rau ntau yam tshuaj thiab cov txheej txheem electrochemical.Lawv tsis kam mus rau corrosive ib puag ncig thiab tshuaj tiv thaiv cov electrodes los ntawm deteriorating, ua kom muaj kev ua haujlwm tsis tu ncua hauv cov xwm txheej hnyav.Qhov no versatility nthuav dav ntawm daim ntawv thov rau graphite electrodes tshaj li kev lag luam steel.
Ib puag ncig tus phooj ywg:
Thaum lub sij hawm steelmaking txheej txheem, cov electrodes tsis tsim tej gases los yog teeb meem by-products.Qhov no ua raws li kev loj hlob thoob ntiaj teb tsom mus rau kev ruaj khov thiab txo qis tag nrho cov pa roj carbon hneev taw ntawm kev lag luam steel.
Graphite electrodes yog ib qho tseem ceeb hauv kev lag luam steel, muab ntau qhov zoo ntawm thermal thiab hluav taws xob conductivity, txhua yam muaj zog, thiab tshuaj lom neeg.Lawv muaj peev xwm tiv taus qhov kub thiab txias, tiv thaiv thermal poob siab, thiab khaws cia ruaj khov ua rau lawv tseem ceeb rau kev tsim cov hlau zoo.Tsis tas li ntawd, lawv cov phooj ywg ib puag ncig ua ke nrog cov kev coj ua kom ruaj khov uas tau txais los ntawm kev lag luam thoob ntiaj teb.Nrog kev nce qib tsis tu ncua hauv kev tsim khoom, graphite electrodes txuas ntxiv hloov zuj zus raws li cov cuab yeej tseem ceeb rau cov txheej txheem steel niaj hnub no.
