Theknoloji ea ho koahela li-electrode tsa graphite, haholo-holo li-antioxidant coatings, e atolosa bophelo ba tsona ba ts'ebeletso haholo ka mekhoa e mengata ea fisik'hemik'hale. Melao-motheo ea mantlha le litsela tsa tekheniki li hlalositsoe ka tsela e latelang:
I. Mekhoa ea Bohlokoa ea Liaparo tsa Antioxidant
1. Ho aroloa ha likhase tse ntšang oksijene
Tlas'a maemo a mocheso o phahameng, bokaholimo ba li-electrode tsa graphite bo ka fihla ho 2,000–3,000°C, bo bakang liketso tse matla tsa oxidation ka oksijene ea sepakapaka (C + O₂ → CO₂). Sena se ikarabella bakeng sa 50–70% ea tšebeliso ea mahlakore a li-electrode. Liaparo tsa antioxidant li etsa likarolo tse teteaneng tsa ceramic kapa tsa tšepe-ceramic ho thibela ka katleho ho kopana ha oksijene le matrix ea graphite. Mohlala:
Liaparo tsa RLHY-305/306: Sebelisa meaho ea boholo ba tlhapi ea nano-ceramic ho theha marang-rang a likhalase mochesong o phahameng, ho fokotsa li-coefficients tsa ho hasana ha oksijene ka ho feta 90% le ho atolosa bophelo ba electrode ka 30-100%.
Liaparo tse ngata tsa Silicon-Boron Aluminate-Aluminium: Sebelisa ho fafatsa ha malakabe ho haha meaho ea gradient. Lera la aluminium le ka ntle le mamella mocheso o kaholimo ho 1,500°C, ha lera la silicon le ka hare le boloka motlakase o tsamaisoang, le fokotsa tšebeliso ea li-electrode ka 18-30% moeling oa 750–1,500°C.
2. Ho Ipholisa le ho Hanela ho Tšabeha ha Thermal
Liaparo li tlameha ho mamella khatello ea mocheso ho tsoa lipotolohong tse pheta-phetoang tsa katoloso/ho honyela. Meralo e tsoetseng pele e fihlella ho itokisa ka:
Li-Composite tsa Nano-Oxide Ceramic Powder-Graphene: Etsa lifilimi tsa oxide e teteaneng nakong ea oxidation ea mohato oa pele ho tlatsa mapetso a manyenyane le ho boloka botšepehi ba ho roala.
Meaho ea Li-Bilayer tsa Polyimide-Boride: Lera la kantle la polyimide le fana ka ho thibela motlakase, ha lera la ka hare la boride le etsa hore filimi e sireletsang e be teng. Modulus gradient e tenyetsehang (mohlala, e fokotsehang ho tloha ho 18 GPa lera la ka ntle ho ea ho 5 GPa lera la ka hare) e fokotsa khatello ea mocheso.
3. Phallo le ho Tiisa Khase tse Ntlafalitsoeng
Mahlale a ho koahela hangata a kopanngoa le boqapi ba meaho, joalo ka:
Moralo oa Lesoba le Menyetsoeng: Meaho e nang le masoba a manyane ka har'a li-electrode, e kopantsoeng le matsoho a sireletsang rabara a annular, e ntlafatsa ho koaloa ha manonyeletso le ho fokotsa likotsi tsa oxidation sebakeng seo.
Ho Kenngwa ka Vacuum: Ho kenella maro a ho kenngwa ka SiO₂ (≤25%) le Al₂O₃ (≤5.0%) ka hara masoba a electrode, ho etsa lera le sireletsang la 3–5 μm le eketsang ho hanyetsa ho bola hararo.
II. Liphetho tsa Ts'ebeliso ea Liindasteri
1. Ho Etsa Tšepe ka Sebōpi sa Arc sa Motlakase (EAF)
Tšebeliso e Fokolitsoeng ea Li-electrode ka Tone ea Tšepe: Li-electrode tse phekotsoeng ka antioxidant li fokotsa tšebeliso ho tloha ho 2.4 kg ho isa ho 1.3–1.8 kg/tonne, e leng phokotso ea 25–46%.
Tšebeliso e Tlase ea Matla: Ho hanyetsa ho koahela ho fokotseha ka 20-40%, ho nolofalletsa ho ba le matla a mangata a hona joale le ho fokotsa litlhoko tsa bophara ba electrode, ho fokotsa tšebeliso ea matla haholoanyane.
2. Tlhahiso ea Silicone ea Sebōpi sa Arc se Nōkiloeng ka Metsi (SAF)
Tšebeliso ea Elektrode e Tsitsitseng: Tšebeliso ea elektrode ea silicon ka ton e theoha ho tloha ho 130 kg ho ea ho ~100 kg, e leng phokotso ea ~30%.
Ho Tsitsisa Sebopeho ho Ntlafaditsweng: Bongata ba modumo bo dula bo le ka hodimo ho 1.72 g/cm³ kamora dihora tse 240 tsa tshebetso e tswelang pele ho 1,200°C.
3. Litšebeliso tsa Sebōpi sa Khanyetso
Ho Tšoarella ha Mocheso o Phahameng: Li-electrode tse phekotsoeng li bontša katoloso ea bophelo ba 60% ho 1,800°C ntle le ho arola kapa ho petsoha ha lesela.
III. Paramethara ea Tekheniki le Papiso ea Ts'ebetso

IV. Tlhahlobo ea Theknoloji le Moruo
1. Melemo ea Litšenyehelo
Litlhare tsa ho koahela li etsa 5-10% ea litšenyehelo tsohle tsa elektrode empa li eketsa bophelo ba tšebeletso ka 20-60%, li fokotsa ka ho toba litšenyehelo tsa elektrode ka tonne ea tšepe ka 15-30%. Tšebeliso ea matla e fokotseha ka 10-15%, e leng se fokotsang litšenyehelo tsa tlhahiso haholo.
2. Melemo ea Tikoloho le ea Sechaba
Ho fokotseha ha maqhubu a ho nkela elektrode sebaka ho fokotsa matla le likotsi tsa basebetsi (mohlala, ho chesoa ke mocheso o phahameng).
E tsamaisana le maano a ho boloka eneji, e fokotsa tlhahiso ea CO₂ ka ~ lithane tse 0.5 ka tonne ea tšepe ka ho sebelisa elektrode e fokolang.
Qetello
Mahlale a ho koahela li-electrode tsa graphite a theha sistimi ea tšireletso e nang le mekhahlelo e mengata ka ho itšehla thajana, ho tsitsisa lik'hemik'hale le ntlafatso ea sebopeho, e leng se ntlafatsang haholo ho tšoarella libakeng tse nang le mocheso o phahameng, tse eketsang oksijene. Tsela ea tekheniki e fetohile ho tloha ho li-coat tsa lera le le leng ho ea ho meaho e kopaneng le thepa e iphekolang. Tsoelo-pele ea nakong e tlang theknolojing ea nanotechnology le thepa e hlophisitsoeng e tla phahamisa ts'ebetso ea ho koahela haholoanyane, e fane ka litharollo tse sebetsang hantle bakeng sa liindasteri tsa mocheso o phahameng.
