Isticmaalka electrodes graphite inta badan waxay la xiriirtaa tayada korantada laftooda, laakiin sidoo kale hawlgalka iyo habka birta samaynta (sida cufnaanta hadda jirta iyada oo loo marayo electrodes, birta dhalaalaysa, tayada birta qashinka ah iyo muddada oksijiinta ee block khilaaf iwm).
(1) Qaybta sare ee korantada waa la wada baabbi'iyey. Isticmaalka waxaa ka mid ah sublimation ee walxaha graphite ee ay sababtay heerkulka sare ee arc iyo luminta falcelinta kiimikada ee u dhaxaysa qaybta ugu badan ee korantada iyo birta dhalaalaysa iyo slag, iyo isticmaalka qaybta ba'an ee korantada ayaa sidoo kale la xidhiidha haddii electrode la geliyo birta dhalaalaysa carburize.
(2) Oxidation luminta dusha sare ee korantada. Sanadihii la soo dhaafay, si loo hagaajiyo heerka dhalaalka ee foornada korantada, hawlgalka oksijiinta afuufista ayaa inta badan la isticmaalaa, taas oo keenta kororka khasaaraha oxidation electrode. Xaaladaha caadiga ah, luminta oksaydhka ee dusha sare ee korantada ayaa xisaabisa ilaa 50% wadarta isticmaalka korantada.
(3) Waayida hadhaaga korantada ama kala-goysyada. Qayb yar oo ka mid ah korantada ama isku-goysyada (ie, hadhaa) oo si joogto ah loo isticmaalo si loogu xidho korantada sare iyo hoose waxay u nugul tahay inay dhacaan oo kordhiyaan isticmaalka.
(4) Waayida jebinta korantada, diirka oogada iyo godadka soo dhacaya. Saddexdan nooc ee khasaaraha korantada ayaa si wada jir ah loogu tilmaamaa khasaare farsamo, halka sababta keentay jabinta korantada iyo dhicista ay tahay qodobka muranka dhaliyay ee shilka tayada ee lagu aqoonsaday warshadda birta ah iyo warshadda soo saarista graphite electrode, sababtoo ah waxa laga yaabaa inay sabab u tahay dhibaatooyinka tayada iyo habaynta ee graphite electrode (gaar ahaan wadajirka korantada), ama waxaa laga yaabaa inay dhibaato ku tahay hawlgalka birta samaynta.
Isticmaalka korantada lama huraanka ah sida oksaydheynta iyo sublimation heerkulka sare waxaa guud ahaan loo yaqaan "cunista saafiga ah", iyo "isticmaalka saafiga ah" oo lagu daray luminta farsamada sida jabinta iyo khasaaraha haraaga ah waxaa loo yaqaan "isticmaalka guud". Waqtigan xaadirka ah, isticmaalka kaliya ee graphite electrode halkii tan ee birta foornada korontada ee Shiinaha waa 1.5 ~ 6kg. Inta lagu jiro habka dhalaalidda birta, korantada ayaa si tartiib tartiib ah oksaydhaysan oo loo wada baabbi'iyey koofiyad. Inta badan la fiirsashada taper of electrode iyo casaanka ee jidhka electrode ee habka samaynta birta waa hab dareen leh oo lagu cabbiro caabbinta oksaydhka ee electrode graphite.
