Mokhoa oa ho fokotsa tšebeliso ea li-electrode
Lilemong tsa morao tjena, ka tsoelo-pele e matla ea indasteri ea tšepe ea tšepe ea sebōpi ea China, hammoho le litlhoko tsa litsebi tsa ho boloka matla le ho fokotsa tšebeliso ea matla le litsebi lapeng le linaheng tse ling li etsa qeto ea mekhoa e meng e sebetsang ka tsela e latelang:
1.Anti-oxidation mochine oa metsi spray graphite electrode
Ka lipatlisiso tsa liteko, ho fafatsa tharollo ea anti-oxidation holim'a li-electrode ho ipakile ho le betere ho emisa ho tloha lehlakoreng la oxidation ea electrode ea graphite, mme matla a anti-oxidation a eketseha ka makhetlo a 6-7. Kamora ho sebelisa mokhoa ona, tšebeliso ea electrode e theohile ho 1.9-2.2kg ho qhibilihisa tonne ea tšepe.
2.Elektrode e sekoti
Lilemong tsa morao tjena, Europe Bophirimela le Sweden li qalile ho sebelisa li-electrode tse se nang letho ha ho etsoa libōpi tsa ferroalloy ore. Li-electrode tse se nang letho, sebopeho sa cylinder, hangata ha li na letho ka hare li tiisitsoe ka khase e sa sebetseng. Ka lebaka la sekoti, maemo a ho baka a ntlafala mme a etsa hore matla a electrode a phahame. Ka kakaretso, e ka boloka li-electrode ka 30% -40%, ho fihlela ho 50% haholo.
3.DC sebōpi sa arc
Sebōpi sa DC electric arc ke mofuta o mocha oa sebōpi sa smelting sa arc se sa tsoa hlahisoa lefatšeng lilemong tsa morao tjena. Ho tsoa ho data e hatisitsoeng kantle ho naha, DC arc sebōpi ke e 'ngoe ea mekhoa e sebetsang ka ho fetisisa ea ho fokotsa tšebeliso ea li-electrode. Ka kakaretso, tšebeliso ea li-electrode e ka fokotsoa ka hoo e ka bang 40% ho isa ho 60%. Ho ea ka litlaleho, tšebeliso ea li-electrode tsa graphite tsa sebōpi sa motlakase se matla sa DC se theohetse ho 1.6kg / t.
