Ukusetyenziswa kwe-electrode yegraphite
Iielectrode zegraphite zenziwe ikakhulu ngepetroleum coke kunye nenaliti yecoke njengemathiriyeli ekrwada kunye netha yetha yamalahle njengesibophelelo.Zenziwa nge-calcining, i-batching, ukuxova, ukucinezela, ukugcoba, i-graphitization kunye ne-machining.Ziye zikhutshwe ngendlela yee-arcs zombane kwisithando sombane sombane.I-conductor eshushu kwaye inyibilikisa intlawulo ngamandla ombane isetyenziswa ikakhulu kwi-steelmaking yesithando sombane.Ngokutsho kwesalathisi somgangatho wayo, inokwahlulwa ibe ngamandla aqhelekileyo, amandla aphezulu kunye namandla aphezulu.
(1) Amandla aqhelekileyo egraphite electrode
Ii-electrode zegraphite ezinoxinano lwangoku olungaphantsi kwe-17A/cm2 zivumelekile ukuba zisetyenziswe, ezisetyenziswa ikakhulu kumaziko ombane aqhelekileyo afana nentsimbi, ukwenza isiliconmaking, kunye nokunyibilikisa kwephosphorus emthubi.
(2) I-electrode yegraphite ene-anti-oxidation coating
I-electrode yegraphite eqatywe nge-anti-oxidation protective layer (graphite electrode antioxidant).Yenza umaleko okhuselayo ophetheyo kunye nokumelana nokushisa okuphezulu kwe-oxidation, ukunciphisa ukusetyenziswa kwe-electrode (19% ~ 50%) ngexesha le-steelmaking, ukwandisa ubomi benkonzo ye-electrode (22% ~ 60%), kunye nokunciphisa ukusetyenziswa kwamandla. ye electrode.Ukukhuthazwa nokusetyenziswa kobu buchwepheshe kunokuzisa ezi ziphumo zilandelayo kwezoqoqosho nezentlalo:
① Ukusetyenziswa kweyunithi ye-electrode yegraphite kuncinci, kwaye ixabiso lemveliso liyancitshiswa ukuya kumlinganiselo othile.Umzekelo, iplanti yokwenza intsimbi, esekwe ekusetyenzisweni kwee-electrode zegraphite ezimalunga nama-35 ngeveki kwiziko lokusulungekisa iLF-level yokuqala ngaphandle kokuvalwa kwemveliso unyaka wonke, kunye nokusetyenziswa kwezitofu zokusulungekisa ezingama-165, emva kokusebenzisa itekhnoloji ye-graphite electrode anti-oxidation. , Ii-electrode zegraphite ezingama-373 (iitoni ezili-153) zinokugcinwa minyaka le.) ii-electrodes, ezibalwe kwi-RMB 16,900 ngetoni nganye ye-electrodes ephezulu-high-high ngonyaka, enokugcina i-RMB 2,585,700.
② I-electrode yegraphite idla umbane omncinci, yonga ukusetyenziswa kombane kwiyunithi nganye yokwenza intsimbi, gcina iindleko zokuvelisa, kwaye wonge amandla!
③ Ekubeni ii-electrode zegraphite zitshintshwa kancinci rhoqo, umsebenzi kunye nomngcipheko wabaqhubi ziyancipha, kwaye ukusebenza kakuhle kwemveliso kuphuculwe.
(3) I-electrode yegraphite enamandla kakhulu.Kuvunyelwe ukusebenzisa i-electrodes ye-graphite kunye nobuninzi obukhoyo be-18-25A / cm2, ngokukodwa isetyenziswe kwiindawo eziphezulu zombane ze-arc zensimbi.
(4) I-electrode yegraphite yamandla aphezulu kakhulu.I-electrode ye-graphite enokuxinana kwangoku ngaphezu kwe-25 A / cm ivumelekile.Isetyenziswa kakhulu kwi-ultra-high power steelmaking electric arc furnace.
