Li-electrode tsa graphite ke karolo e ka sehloohong ea ho futhumatsa e sebelisoang ka sebōping sa arc ea motlakase, e leng mokhoa oa ho etsa tšepe moo masala a likoloi tsa khale kapa lisebelisoa tsa motlakase a qhibilihang ho hlahisa tšepe e ncha.
Lifono tsa motlakase tsa arc li theko e tlase ho li haha ho feta lifono tsa setso tsa ho phatloha, tse etsang tšepe ka tšepe ea tšepe 'me li fepeloa ke mashala a ho baka. Empa litšenyehelo tsa ho etsa tšepe li phahame kaha li sebelisa likhechana tsa tšepe 'me li tsamaisoa ke motlakase.
Li-electrode ke karolo ea sekoahelo sa sebōpi 'me li kopanngoa ka likholomo. Motlakase o feta ka har'a li-electrode, o etsa selikalikoe sa mocheso o matla o qhibilihisang tšepe e senyehileng. Li-electrode li fapana haholo ka boholo empa li ka ba bophara ba limithara tse 0.75 (maoto a 2 le halofo) le bolelele ba limithara tse 2.8 (maoto a 9). E kholo ka ho fetisisa e boima ba lithane tse fetang metric tse peli.
Ho nka di-electrode tsa graphite tse fihlang ho 3 kg (6.6 lb) ho hlahisa thane e le nngwe ya tshepe.
Ntlha ea elektrode e tla fihla likhatong tse 3,000 tsa Celsius, e leng halofo ea mocheso oa bokaholimo ba letsatsi. Li-electrode li entsoe ka graphite hobane ke graphite feela e ka mamellang mocheso o matla joalo.
Ebe sebopi se sekamela lehlakoreng la sona ho tshela tshepe e qhibilihisitsweng ka hara dibakete tse kgolo tse bitswang diladle. Diladle di ntoo isa tshepe e qhibilihisitsweng ho ya caster ya feme ya tshepe, e etsang dihlahiswa tse ntjha ho tswa ho dilahlwa tse sebedisitsweng hape.
Motlakase o hlokahalang bakeng sa ts'ebetso ena o lekane ho matlafatsa toropo e nang le baahi ba 100,000. Ho qhibiliha ho hong le ho hong ka ontong ea sejoale-joale ea arc ea motlakase hangata ho nka metsotso e ka bang 90 mme ho etsa lithane tse 150 tsa tšepe, e leng se lekaneng bakeng sa likoloi tse ka bang 125.
Coke ea nale ke thepa e tala e ka sehloohong e sebelisoang li-electrode tseo bahlahisi ba reng li ka nka likhoeli tse tšeletseng ho li etsa ka lits'ebetso tse kenyeletsang ho baka le ho baka hape ho fetola coke hore e be graphite.
Ho na le nale coke e thehiloeng peteroleng le nale coke e thehiloeng mashaleng, 'me ka bobeli li ka sebelisoa ho hlahisa li-electrode tsa graphite. 'Pet coke' ke sehlahisoa se setseng sa ts'ebetso ea ho hloekisa oli, ha nale coke e thehiloeng mashaleng e etsoa ka sekontiri sa mashala se hlahang nakong ea tlhahiso ea coke.
