UHP graphite electrode 650 * 2700mm
I-electrode ye-graphite ye-ultra-high-power ifanelekile kwi-oven arc ye-arc yombane ye-ultra-high-power, ngaphezu kweetoni ezingama-50 zombane ze-arc;umjikelo wokunyibilikisa ngama-25% mfutshane kuneziko zombane eziqhelekileyo ze-arc, ukunciphisa ukusetyenziswa kwamandla kunye nokuphucula ukusebenza kakuhle kwemveliso.Le ilandelayo i-Dan charcoal graphite electrode iya kwazisa ukusetyenziswa kwe-ultra-high power graphite electrode kunye ne-standard kunye ne-ultra-high power graphite electrode process.
I-electrode ye-graphite ye-ultra-high yenziwe nge-coke yenaliti ephezulu, eveliswa ngeendlela ezingaphezu kweshumi elinesibini ezifana ne-calcination, extrusion, impregnation, i-graphitization kunye ne-machining.ixesha elide.Ivumela ukuxinana kwangoku ukuba kukhulu kune-25A / cm2, kwaye isetyenziselwa ukunyibilikisa intsimbi ecocekileyo kunye nentsimbi ekhethekileyo.
Kwiintsuku zangaphambili, i-electrodes yasekhaya ye-ultra-high-power graphite yayixhomekeke kakhulu ekuthengeni ngaphandle.Ngenxa yobuxhakaxhaka betekhnoloji kumazwe aphuhlileyo eYurophu, eMelika naseJapan, imveliso yasekhaya ibikude ukuba ihlangabezane nemfuno.Ngophuhliso loshishino lwensimbi, ezininzi ze-graphite electrode
abavelisi batyale imali eninzi kunye nobuchwepheshe kwi-R&D kunye nokuveliswa kwe-electrode yegraphite yamandla aphezulu.I-Dan charcoal graphite electrode iphumelele i-UHP700mm ultra-high power graphite electrode ukubonelela ngeentsimbi zentsimbi zangaphandle kunye novavanyo olufanelekileyo kunye nokuveliswa kobuninzi.UHP800mm sele iphuhliswe ngokupheleleyo.Iielectrode zegraphite ezinamandla kakhulu.
Ukwenziwa kwentsimbi yesithando sombane ngoyena msebenzisi uphambili weeelectrode zegraphite.imveliso yentsimbi yesithando sombane yelizwe lam ithatha malunga ne-18% yemveliso yentsimbi ekrwada, kunye ne-electrode yegraphite ye-steelmaking account ye-70% ukuya kuma-80% yokusetyenziswa kwe-electrode yegraphite iyonke.I-steelmaking yesithando sombane kukusebenzisa i-electrode yegraphite ukwazisa okwangoku kwiziko, kwaye usebenzise umthombo wobushushu obuphezulu obuveliswa yi-arc phakathi kokuphela kwe-electrode kunye nentlawulo yokunyibilika.
Iziko lombane eliphantsi kwamanzi elishushu lisetyenziselwa ukuveliswa kwe-silicon yoshishino kunye ne-phosphorus ephuzi, njl. amandla akhutshwa yintlawulo yokuchasa ngokwawo asetyenziselwa ukufudumeza intlawulo.Ii-arc eziphantsi kwamanzi ezinoxinzelelo oluphezulu kufuneka zisebenzise i-electrode yegraphite.Umzekelo, malunga ne-100kg ye-electrode yegraphite isetyenziselwa ukuvelisa i-1t yesilicon, kwaye malunga ne-40kg ye-electrode yegraphite isetyenziselwa ukuvelisa i-1t ye-phosphorus etyheli.
Amaziko okwenziwa kwegrafiti ukuze kuveliswe iimveliso zegraphite, iziko lokunyibilikisa iglasi enyibilikayo, kunye neziko lombane lokuvelisa isilicon carbide zonke zizitofu zokuxhathisa.Izinto ezikwi-furnace zombini zi-resistors zokufudumeza kunye nezinto eziza kufudumeza.Ngokuqhelekileyo, i-electrode ye-graphite conductive ifakwe ekupheleni kwesithando somlilo.Kwindonga yentloko yesithando somlilo ngezantsi, i-electrode yegraphite esetyenziswe apha iyachithwa ngokuqhubekayo.
Izikhewu ze-electrode zegraphite zikwasetyenziselwa ukucubungula iimveliso ezahlukeneyo zegraphite ezinje ngecrucibles, ukubumba, izikhephe kunye nezinto zokufudumeza.Ngokomzekelo, kwishishini leglasi ye-quartz, iitoni ezili-10 ze-graphite electrode blanks ziyadingeka kwi-1 toni nganye yombhobho wokudibanisa wombane oveliswayo;I-100 kg ye-graphite electrode blanks iyadingeka kwi-1 toni nganye yezitena ze-quartz eziveliswayo.
Ngokwamandla ombane we-arc ombane, yahlulwe kwiziko lombane eliqhelekileyo le-arc (ngaphantsi kwe-400kV.A/t), isithando sombane esinamandla aphezulu (400kV.A/t ~ 700kV.A/t), amandla aphezulu aphezulu isithando sombane se-arc (ngaphezu kwe-700kV.A/t) .Ngokomgaqo wesiphi isithando sombane se-arc esihambelana neyiphi i-electrode yegraphite yamandla, i-electrode ye-ultra-high power graphite electrode isetyenziswa kunye ne-ultra-high power electric arc furnace.
"YB/T 4088-2015 Graphite Electrode Standard"
"YB/T4089-2015 High Power Graphite Electrode Standard"
"YB/T4090-2015 Ultra-high Power Graphite Electrode Standard"
Inkqubo yokuvelisa i-electrode yegraphite iqulunqwe ikakhulu ngokubala kwezinto ezikrwada, i-extrusion yezithako, ukudipha kunye nokuqhotsa, igraphitization kunye nokulungiswa koomatshini.Kukho iiyantlukwano ezithile kumjikelo wemveliso kunye nezinto ezikrwada ze-electrode ezinamandla ahlukeneyo.
