Ku bwoko butandukanye bw'ibicuruzwa bya electrode ya karuboni na grafiti, hakurikijwe ikoreshwa ryabyo ritandukanye, hari ibisabwa byihariye byo gukoresha n'ibipimo by'ubuziranenge. Mu gihe tureba ubwoko bw'ibikoresho fatizo bigomba gukoreshwa ku gicuruzwa runaka, tugomba kubanza kwiga uburyo bwo kuzuza ibi bisabwa byihariye n'ibipimo by'ubuziranenge.
(1) Guhitamo ibikoresho fatizo byo gukoresha electrode ya grafiti ikoreshwa mu gutunganya ibyuma nka EAF.
Electrode ya grafiti ikoreshwa mu gutunganya ibyuma nka EAF igomba kuba ifite ubushobozi bwo gutwara ibintu neza, imbaraga zikwiye za mekanike, ubushobozi bwo kudashira no gushyushya ku bushyuhe bwinshi, ubushobozi bwo kurwanya ingese n'umwanda muke.
① Electrodes za grafiti nziza cyane zikorwa muri peteroli, pitch coke n'ibindi bikoresho fatizo bike. Ariko, gukora electrode ya grafiti bisaba ibikoresho byinshi, inzira ndende n'ikoranabuhanga rigoye, kandi ingufu za electrode ya grafiti ya 1 t ni 6000 ~ 7000 kW · H.
② Anthracite nziza cyangwa coke ya metallurgical ikoreshwa nk'ibikoresho fatizo mu gukora electrode ya karuboni. Gukora electrode ya karuboni ntibikenera ibikoresho bya graphitization, kandi izindi nzira zo kuyikora ni zimwe no gukora electrode ya grafiti. Ubushobozi bwo gutwara electrode ya karuboni ni bubi cyane kurusha electrode ya grafiti. Ubushobozi bwo kwirinda electrode ya karuboni muri rusange buruta inshuro 2-3 electrode ya grafiti. Ivu rihinduka bitewe n'ubwiza bw'ibikoresho fatizo, ni ukuvuga hafi 10%. Ariko nyuma yo gusukurwa by'umwihariko, ivu rishobora kugabanuka kugeza munsi ya 5%. Ivu rishobora kugabanuka kugera kuri 1.0% niba ibicuruzwa bikosowe. Electrode ya karuboni ishobora gukoreshwa mu gushongesha icyuma gisanzwe cya EAF na ferroalloy.
③ Hakoreshejwe grafiti karemano nk'ibikoresho fatizo, electrode karemano ya grafiti yarakozwe. Grafiti karemano ishobora gukoreshwa gusa nyuma yo gutoranywa neza no kugabanuka kw'ivu ryayo. Ubushobozi bwo kurwanya electrode karemano ya grafiti buri hafi kabiri ugereranyije n'ubwo electrode ya grafiti. Ariko imbaraga za mekanike ni nkeya, byoroshye kumena iyo ikoreshejwe. Mu gace gafite graphite nyinshi karemano, electrode karemano ya grafiti ishobora gukorwa kugira ngo itange EAF ntoya kugira ngo ishongeshe icyuma gisanzwe cya EAF. Iyo ikoresheje grafiti karemano kugira ngo ikore electrode iyobora, ibikoresho n'ikoranabuhanga biroroshye kubikemura no kubikoresha neza.
④ Electrode ya grafiti ikoreshwa mu gukora electrode yavuguruwe (cyangwa electrode yavunitse ya grafiti) binyuze mu gusya no gusya imyanda cyangwa imyanda. Ivu ry'umusaruro ntabwo riri hejuru (hafi 1%), kandi ubushobozi bwo gutwara ibintu ni bubi kurusha electrode ya grafiti. Ubushobozi bwo guhangana na yo bungana n'inshuro 1.5 z'ubushobozi bwo guhangana na yo, ariko ingaruka zayo ni nziza kuruta electrode karemano ya grafiti. Nubwo byoroshye kumenya ikoranabuhanga n'ibikoresho byo gukora electrode yavuguruwe, isoko y'ibikoresho fatizo byo gushushanya ni nke, bityo ubu buryo si bwo bw'iterambere.
