400 UHP electrode ea graphite
Li-electrode tsa graphite li sebelisoa haholo ts'ebetsong ea ho etsa tšepe. Lisebelisoa tsa tšepe li qhibiliha ka seboping sa motlakase sa arc ebe lia sebelisoa hape. Joalo ka mofuta oa conductor, ke karolo ea bohlokoa mofuteng ona oa
UHP graphite electrode e entsoe haholo ka coke ea nale ea boleng bo holimo, 'me e sebelisoa haholo litsing tsa arc tsa motlakase tse matla haholo. E khona ho jara boima ba hona joale ho feta 25A/cm2

Mokhoa oa tlhahiso
Graphite electrode e entsoe haholo ka coke ea petroleum le coke ea nale, e kopantsoeng le sekontiri sa mashala, ho kenella lits'ebetsong tsa calcinations, ho luba, ho etsa, ho baka, graphitizing le machining, qetellong ea fetoha lihlahisoa. Mona ke litlhaloso tse ling tsa ts'ebetso ea tlhahiso:
Kneading: Ho fuduha le ho kopanya palo e itseng ya carbon particles le phofo ka tekanyo e itseng ya binder mochesong o itseng, tshebetso ena e bitswa ho duba.
Mosebetsi wa ho duba
① Kopanya mefuta eohle ea lisebelisoa tse tala ka ho lekana, 'me ka nako e ts'oanang u etse lisebelisoa tse tiileng tsa carbon tsa boholo bo fapaneng ka ho kopanya le ho tlatsa, le ho ntlafatsa boleng ba motsoako;
②Kamora ho eketsa asphalt ea mashala, kopanya lisebelisoa tsohle ka tieo.
③ Lithaba tse ling tsa mashala li kenella ka har'a li-voids tse ka hare, tse ntlafatsang le ho feta ho tiisa le ho khomarela pente.
Ho theha: Motsoako oa kneaded carbon peste o fetisetsoa 'meleng o motala (kapa sehlahisoa se setala) se nang le sebōpeho se itseng, boholo, boima le matla ka har'a thepa ea ho bopa. Peista e na le deformation polasetiki tlas'a matla a ka ntle.
Ho besoa ho boetse ho bitsoa ho baka, Ke phekolo e phahameng ea mocheso, e etsang hore sekontiri sa mashala se be le carbonized ho coke e entsoeng, e kopanyang likaroloana tsa carbonaceous le likaroloana tsa phofo hammoho le matla a phahameng a mochine, ho hanyetsa ka tlaase, botsitso bo molemo ba mocheso le botsitso ba lik'hemik'hale.
Ho chesa ha bobeli ke ho baka nako e 'ngoe hape, ho etsa hore sekontiri se phunyeletsang se be le carbonized. Li-electrode (mefuta eohle ntle le RP) le li-nipples tse hlokang hore li be ngata haholo li lokela ho apehoa lekhetlo la bobeli, le li-nipples tse tharo-dip four-bake kapa two-dip three-bake.
