Li-electrode tsa graphite ke ntho e ka sehloohong ea ho futhumatsa e sebelisoang ka sebōping sa motlakase sa arc, mokhoa oa ho etsa tšepe moo masela a likoloi kapa lisebelisoa tsa khale a qhibilihang ho hlahisa tšepe e ncha.
Lisebelisoa tsa motlakase tsa arc li theko e tlaase ho haha ho feta libōpi tsa khale tsa ho phatloha, tse etsang tšepe ka tšepe ea tšepe 'me li besoa ke mashala a coking. Empa litšenyehelo tsa ho etsa litšepe li holimo kaha li sebelisa makumane a tšepe 'me li tsamaisoa ke motlakase.
Li-electrode ke karolo ea sekoahelo sa sebōpi 'me li bokelloa ka litšiea. Motlakase o feta ka har'a li-electrode, o etsa arc ea mocheso o matla o qhibilihisang tšepe e setseng. Li-electrode li fapana haholo ka boholo empa li ka ba bolelele ba limithara tse 0.75 (maoto a 2 le halofo) le bolelele ba limithara tse 2,8. E kholo ka ho fetisisa e boima ba lithane tse fetang tse peli tsa metric.
Ho nka lik'hilograma tse 3 (6.6 lb) tsa li-electrode tsa graphite ho hlahisa tonne e le 'ngoe ea tšepe.
Ntlheng ea electrode e tla fihla likhatong tse 3 000 tsa Celsius, e leng halofo ea mocheso o holim'a letsatsi. Li-electrode li entsoe ka graphite hobane ke graphite feela e khonang ho mamella mocheso o matla joalo.
Joale sebōpi se sekamisoa ka lehlakoreng la sona ho tšela tšepe e qhibilihisitsoeng ka linkhong tse khōlōhali tse bitsoang li-ladle. Ka mor'a moo, lilae tsena li isa tšepe e qhibilihisitsoeng ka har'a leloala la tšepe, e leng se etsang lihlahisoa tse ncha ho tloha masakeng a sebelisoang hape.
Motlakase o hlokahalang bakeng sa ts'ebetso ena o lekane ho matlafatsa toropo e nang le baahi ba 100,000. E 'ngoe le e' ngoe e qhibilihang ka har'a sebōpi sa sejoale-joale sa arc ea motlakase hangata e nka metsotso e ka bang 90 mme e etsa lithane tse 150 tsa tšepe, tse lekaneng likoloi tse ka bang 125.
Needle coke ke lisebelisoa tse ka sehloohong tse sebelisoang ka li-electrode tseo bahlahisi ba reng li ka nka likhoeli tse tšeletseng ho li etsa ka mekhoa e kenyeletsang ho baka le ho baka hape ho fetola coke hore e be graphite.
Ho na le coke ea nale e thehiloeng ho petroleum le coke ea nale e thehiloeng ka mashala, 'me e ka sebelisoa ho hlahisa li-electrode tsa graphite. 'Pet coke' ke sehlahisoa sa ho hloekisoa ha oli, ha coke ea nale e entsoeng ka mashala e entsoe ka sekontiri sa mashala se hlahang nakong ea tlhahiso ea coke.
