UHP Graphite Electrode kunye Iingono
1. Intshayelelo :
UHP graphite electrodeisetyenziselwa ukusetyenzwa kwakhona kwentsimbi kwishishini le-arc yombane.Inxalenye yayo ephambili yi-coke yenaliti enexabiso eliphezulu, eyenziwe nge-petroleum okanye i-tar yamalahle.I-electrode yegraphite ifakwe kwimilo ye-cylindrical kwaye indawo edibeneyo ifakwe kwisiphelo ngasinye.Ngale ndlela, i-electrode yegraphite inokuhlanganiswa kwikholamu ye-electrode usebenzisa i-electrode connector.
Ukuze kuhlangatyezwane neemfuno zentsebenzo ephezulu yokusebenza kunye nexabiso eliphantsi lilonke, umthamo omkhulu wesithando somlilo se-arc samandla aphezulu siya sithandwa ngakumbi.Ngoko ke, i-electrode ye-graphite ye-UHP enobubanzi obungaphezulu kwe-500 mm iya kulawula imarike
2. Iimpawu

Iziko le-arc eliphantsi kwamanzi.
Ladle eziko.
(1) I-electrode yegraphite yamandla rhoqo
Kuvunyelwe ukusebenzisa i-electrode yegraphite kunye noxinano lwangoku olungaphantsi kwe-17a / cm2, esetyenziswa kakhulu kwiziko lombane eliqhelekileyo lokwenza intsimbi, ukunyibilika kwesilicon, ukunyibilikisa kwe-phosphorus etyheli, njl.
(2) I-electrode yegraphite ekwaziyo ukumelana ne-oxidation
I-electrode yegraphite eqatywe ngomaleko we-antioxidant protective layer (graphite electrode antioxidant).Yenza umaleko okhuselayo onokuqhuba umbane kwaye uxhathise i-oxidation ephezulu yokushisa, ukunciphisa ukusetyenziswa kwe-electrode ngexesha le-steelmaking (19% ~ 50%), ukwandisa ubomi benkonzo ye-electrode (22% ~ 60%), kunye nokunciphisa ukusetyenziswa kwamandla ombane. ye electrode.Ukuthandwa kunye nokusetyenziswa kobu buchwepheshe kunokuzisa iziphumo ezinjalo kwezoqoqosho nezentlalo:
① Ukusetyenziswa kweyunithi ye-electrode yegraphite kuncinci, kwaye ixabiso lemveliso liyancitshiswa ukuya kumlinganiselo othile.Umzekelo, kwiplanti yokwenza intsimbi, esekwe ekusetyenzisweni kwe35pcs graphite electrode ngeveki kunye neziko lokusulungekisa i165 kwiprimary LF yokuhluza isithando somlilo ngaphandle kokuvalwa unyaka wonke, 373pcs graphite electrode inokugcinwa minyaka le emva kokuba igraphite electrode oxidation resistance technology. yamkelwe
(iitoni ezili-153) i-electrode, ebalwa kwi-3000USD ngetoni ye-electrode yamandla aphezulu kakhulu ngonyaka, i-USD 459,000 inokugcinwa.
② I-electrode yegraphite idla amandla amancinci, igcina iyunithi yokusetyenziswa kwamandla ensimbi, igcina iindleko zemveliso kwaye igcina amandla!
③ Ngenxa yokuba i-electrode yegraphite iguqulwa ngamaxesha amancinci, inani labasebenzi kunye nomngcipheko we-coefficient yabaqhubi bayancitshiswa, kunye nokusebenza kakuhle kwemveliso kuphuculwe.
④ I-electrode yegraphite yinto ephantsi yokusetyenziswa kunye nemveliso yongcoliseko oluphantsi.Namhlanje, xa ukugcinwa kwamandla, ukunciphisa ukukhutshwa kunye nokukhuselwa kokusingqongileyo kukhuthazwa, kubaluleke kakhulu ukubaluleka kwentlalo.
Le teknoloji isekwinqanaba lophando kunye nophuhliso e-China, kwaye abanye abavelisi basekhaya baye baqala ukuyivelisa.Isetyenziswe kakhulu eJapan nakwamanye amazwe aphuhlileyo.Okwangoku, kukwakho iinkampani ezikhethekileyo ekungeniseni le nto yokukhusela i-anti-oxidation e-China.
(3) I-electrode yegraphite yamandla aphezulu.I-electrode ye-graphite ene-concentration yangoku ye-18 ~ 25A / cm2 ivumelekile ukuba isetyenziswe, esetyenziswa kakhulu kwisithando sombane se-arc esine-steelmaking.
(4)Ultra high power graphite electrode.I-electrode ye-Graphite ye-UHP enoxinano lwangoku olukhulu kune-25A / cm2 ivumelekile.Isetyenziswa ikakhulu kwi-ultra-high power steelmaking electric arc furnace.
