Kubwoko butandukanye bwa karubone na grafite ya electrode yibicuruzwa, ukurikije imikoreshereze yabo itandukanye, hariho ibisabwa byihariye byo gukoresha nibipimo byiza. Mugihe dusuzumye ubwoko bwibikoresho fatizo bigomba gukoreshwa kubicuruzwa runaka, dukwiye kubanza kwiga uburyo bwo kuzuza ibyo bisabwa byihariye nibipimo byiza.

Imiyoboro ya grafite ya electrode ikoreshwa mugikorwa cya electrometallurgie nko gukora ibyuma bya EAF bigomba kuba bifite imiyoboro myiza, imbaraga zumukanishi, kurwanya neza kuzimya no gushyuha mubushyuhe bwinshi, kurwanya ruswa hamwe nibirimo umwanda muke.
Electro Ubwoko bwiza bwa grafite electrode ikorwa muri peteroli ya peteroli, kokiya ya pisine nibindi bikoresho bito byivu. Nyamara, umusaruro wa electrode ya grafite ikenera ibikoresho byinshi, inzira ndende kandi ikorana buhanga, kandi ingufu za 1 t grafite electrode ni 6000 ~ 7000 kW · H.
Oke Indwara nziza ya anthracite cyangwa metallurgical coke ikoreshwa nkibikoresho fatizo kugirango ikore karubone electrode. Umusaruro wa electrode ya karubone ntukeneye ibikoresho byo gushushanya, nibindi bikorwa byo gukora ni kimwe no gukora electrode ya grafite. Imikorere ya electrode ya karubone ni mbi cyane kuruta iyo electrode ya grafite. Kurwanya karubone electrode muri rusange iruta inshuro 2-3 ugereranije na grafite electrode. Ibirimo ivu biratandukanye nubwiza bwibikoresho fatizo, bingana na 10%. Ariko nyuma yo gukora isuku idasanzwe, ivu rya anthracite rirashobora kugabanuka kugeza munsi ya 5%. Ivu ryibicuruzwa birashobora kugabanuka kugera kuri 1.0% mugihe ibicuruzwa byongeye gushushanywa. Carbone electrode irashobora gukoreshwa mugushongesha ibyuma bisanzwe bya EAF na ferroalloy
③ Gukoresha grafite karemano nkibikoresho fatizo, electrode naturel yakozwe. Igishushanyo mbonera gishobora gukoreshwa gusa nyuma yo gutoranywa neza kandi ivu ryacyo rikagabanuka. Kurwanya amashanyarazi ya grafite karemano ni hafi kabiri ya electrode ishushanyije. Ariko imbaraga za mashini ni nkeya, byoroshye gucika mugihe ukoresheje. Mu gace gafite umusaruro mwinshi wa grafite, electrode karemano irashobora gukorwa kugirango itange EAF ntoya kugirango ishongeshe ibyuma bya EAF. Iyo ukoresheje grafite karemano kugirango ubyare electrode ikora, ibikoresho nikoranabuhanga biroroshye kubikemura no kuyobora.
Electro Graphite electrode ikoreshwa mugukora electrode nshya (cyangwa yashushanyije electrode yamenetse) binyuze mu kumenagura no gusya gutema imyanda cyangwa imyanda. Ibivu byivu mubicuruzwa ntabwo biri hejuru (hafi 1%), kandi imiyoboro yabyo ni mibi kurenza iyo electrode ishushanyije. Kurwanya kwayo ni inshuro zigera kuri 1.5 z'ubushushanyo bwa electrode ishushanyije, ariko ingaruka zayo zo kuyikoresha ni nziza kuruta izisanzwe ya electrode. Nubwo byoroshye kumenya ikoranabuhanga nibikoresho byo gukora electrode yongeye kuvuka, isoko yibikoresho yo gushushanya ni bike, ubwo buryo rero ntabwo aricyerekezo cyiterambere.
