Intangiriro ya Graphite electrode

Graphite electrodeikoreshwa cyane cyane mu gukora ibyuma bya EAF. Gukora itanura ry'amashanyarazi ni ugukoresha amashanyarazi ya grafite kugirango yinjize amashanyarazi mu itanura. Umuyaga ukomeye utanga arc isohoka binyuze muri gaze kumpera yo hepfo ya electrode, kandi ubushyuhe butangwa na arc bukoreshwa mugushonga. Ukurikije ubushobozi bwitanura ryamashanyarazi, electrode ya grafite ifite diameter zitandukanye. Kugirango ukore electrode idahwema gukoreshwa, electrode ihujwe na electrode ihujwe hamwe. Uwitekaamashanyarazikubukora ibyuma bingana na 70-80% yumubare wuzuye wa electrode ya grafite. 2 、 Ikoreshwa mu itanura ryamashanyarazi. Ikiranga nuko igice cyo hepfo ya electrode iyobora yashyinguwe mumashanyarazi. Kubwibyo, usibye ubushyuhe butangwa na arc hagati yisahani yamashanyarazi nubushyuhe, ubushyuhe nabwo buterwa no kurwanya kwishyurwa iyo umuyoboro unyuze mumashanyarazi. 3 fur Itanura rya Graphitisation, itanura ryo gushonga ibirahuri hamwe nitanura ryamashanyarazi yo gukora ibicuruzwa bya grafite byose ni itanura rirwanya. Ibikoresho byo mu itanura ntabwo birwanya ubushyuhe gusa, ahubwo nibintu bishyushya. Mubisanzwe, amashanyarazi ya grafite ya electrode yinjizwa mumatara yumutwe wumutwe kumpera yumuriro, bityo electrode ikora ntabwo ikoreshwa ubudahwema.

Imirima yo gusaba:

(1) Ikoreshwa mumashanyarazi arc ibyuma byo gukora itanura, numukoresha munini waamashanyarazi. Mu Bushinwa, umusaruro wa EAF ibyuma bingana na 18% by’ibyuma biva mu mahanga, naho electrode ya grafite yo gukora ibyuma bingana na 70% ~ 80% by’ikoreshwa rya electrode ya grafite. Gukora itanura ry'amashanyarazi ni ugukoresha electrode ya grafite kugirango yinjize amashanyarazi mu itanura, kandi ukoreshe ubushyuhe bwo hejuru bwubushyuhe butangwa na arc hagati yimpera ya electrode nuburyo bwo gushonga.

2) Ikoreshwa mu itanura rya arc ryarohamye; itanura ryamazi ya arc ikoreshwa cyane cyane mugukora silikoni yinganda na fosifore yumuhondo, nibindi birangwa nuko igice cyo hepfo ya electrode ikora gishyingurwa mumashanyarazi, kigakora arc murwego rwo kwishyuza, no gushyushya umuriro ukoresheje ingufu zubushyuhe byakozwe no kurwanya kwishyurwa ubwabyo. Itanura ryamazi ya arc hamwe nubucucike buri hejuru ikenera electrode ya grafite, kurugero, hafi 100kg electrode ya grafite irakenewe kuri buri musaruro wa silicon 1t, kandi hafi 100kg ya electrode ya grafite irakenewe kuri buri musaruro wa silikoni 1t Hafi 40 kg ya electrode ya grafite irakenewe kuri t umuhondo fosifore.

(3) Ikoreshwa mu itanura rirwanya; itanura rya grafitisation yo gukora ibicuruzwa bya grafite, itanura ryo gushonga ibirahure nitanura ryamashanyarazi yo gukora karbide ya silicon byose ni itanura rirwanya. Ibikoresho biri mu itanura byombi birwanya ubushyuhe nibintu bishyushye. Mubisanzwe, amashanyarazi ya grafitike yinjizwa mu rukuta rwumutwe wumutwe urangije itanura rirwanya, kandi electrode ya grafite ikoreshwa hano ntabwo ikomeza gukoreshwa.

(4) Ikoreshwa mugutegura imiterere yihariyeibicuruzwa bya grafite; ubusa bwa electrode ya grafite nayo ikoreshwa mugutunganya ibicuruzwa bitandukanye bya grafite nkibintu byingenzi, bibumba, ibyombo byubwato hamwe nubushyuhe. Kurugero, muruganda rwa quartz ibirahuri, 10t ya grafite electrode yubusa irakenewe kuri buri 1t yamashanyarazi; 100kg ya grafite electrode yubusa irakenewe kuri buri matafari ya 1t quartz.
