550mm yakakwirira simba graphite electrode
HP graphite electrode inonyanya kugadzirwa nepetroleum coke uye tsono coke, Inokwanisa kutakura density iripo 18-25A/cm2.Yakagadzirirwa simba remagetsi arc furnace simbi-kugadzira.
Nzira dzemazuva ano dzekugadzira simbi dzinonyanya kusanganisira kushandura simbi uye kugadzirwa kwesimbi yemagetsi.Musiyano wakanyanya kukosha pakati peiyo electric furnace steelmaking method uye inoshandura steelmaking nzira ndeyokuti electric furnace steelmaking nzira inoshandisa simba remagetsi sechitubu chekupisa, uye yemagetsi arc furnace steelmaking nzira ndiyo inonyanya kushandiswa.
EAF kugadzirwa kwesimbi kunobva pane yemagetsi arc inogadzirwa nekuyerera pakati pe electrode nechaji, iyo inoshandura simba remagetsi kuita rinopisa simba muarc mwenje, uye inoshandisa yakananga chiito cheradiation uye arc kupisa nekunyungudutsa simbi uye slag kunyunguduka. simbi uye alloys emhando dzakasiyana-siyana.

Graphite electrode kuumbwa
1.Petroleum coke yakasviba uye ine porous, kabhoni ndiyo inonyanya kuumbwa, uye madota akadzika kwazvo, kazhinji pasi pe0.5%.
Petroleum coke inogona kukamurwa kuita marudzi maviri ecoke mbishi uye calcined coke zvinoenderana nekupisa kwekupisa.Iyo yekutanga ine huwandu hukuru hwechinhu chinoputika uye ine yakaderera mechanical simba.Iyo calcined coke inowanikwa nekuverengera iyo coke mbishi.
Petroleum coke inogona kupatsanurwa kuita yakakwira sarufa coke (ine sulfur zviri pamusoro pe1.5%), yepakati sulfur coke (ine sulfur content 0.5% -1.5%), uye yakaderera sulfur coke (ine sulfur content pazasi 0.5%) zvichienderana nesarufa level.Graphite electrodes uye zvimwe zvigadzirwa zve graphite zvekugadzira zvinowanzogadzirwa uchishandisa yakaderera sulfur coke.
2.Needle coke imhando yepamusoro-soro yekodha ine yakajeka fiber texture, kunyanya yakaderera thermal kuwedzera coefficient uye nyore graphitization.Naizvozvo, tsono coke chinhu kiyi mbishi yekugadzira yakakwirira-simba kana Ultra-yakakwirira-simba graphite maelectrode anoratidzwa neakaderera resistivity, diki yekuwedzera kupisa kwekuwedzera, uye yakanaka yekupisa kuvhunduka kuramba.
3.Coal pitch ndechimwe chezvinhu zvakakosha zvemarasha tar mushure mekugadzirisa kwakadzika.Musanganiswa wemahydrocarbon akawanda.Coal pitch inoshandiswa sebhainda uye kuisa pamuviri.Kuita kwayo kune simba guru pamhando ye graphite electrodes.
