Ho eketsa Tlhahiso ea Litšepe ka Theknoloji ea Motlakase ea Arc Furnace
- Sebōpi sa motlakase sa arc se nka makumane a tšepe, DRI, HBI (tšepe ea briquetted e chesang, e kopantseng DRI), kapa tšepe ea kolobe e le sebopeho se tiileng, ebe e li qhibilihisa ho hlahisa tšepe. Tseleng ea EAF, motlakase o fana ka matla a ho qhibilihisa lijo.
- Graphite electrode e sebelisoa haholo-holo ts'ebetsong ea ho etsa tšepe ea motlakase ea arc (EAF), ho qhibilihisa makumane a tšepe. Li-electrode li entsoe ka graphite ka lebaka la bokhoni ba eona ba ho mamella mocheso o phahameng. Ho EAF, ntlha ea eleketrode e ka fihla ho Fahrenheit tse 3 000, e leng halofo ea mocheso o holim'a letsatsi. Boholo ba li-electrode bo fapana haholo, ho tloha ho 75mm ka bophara, ho ea ho tse kholo joaloka 750mm ka bophara, le ho fihlela ho 2,800mm ka bolelele.
- Ho phahama ha theko ea li-electrode tsa graphite ho ile ha nyolosetsa litšenyehelo tsa limilone tsa EAF. Ho hakanngoa hore EAF e sebelisa hoo e ka bang 1.7 kg ea li-electrode tsa graphite ho hlahisa metric tonne e le 'ngoe ea tšepe.
- Ho phahama ha theko ho bakoa ke ho kopanngoa ha indasteri, lefats'e ka bophara, ho koaloa ha bokhoni Chaena, ka mor'a taolo ea tikoloho, le kholo ea tlhahiso ea EAF lefatšeng ka bophara. Sena se hakanngoa hore se tla eketsa litšenyehelo tsa tlhahiso ea EAF ka 1-5%, ho itšetlehile ka mekhoa ea ho reka thepa ea leloala, 'me sena se ka' na sa thibela tlhahiso ea tšepe, kaha ha ho na sebaka sa li-electrode tsa graphite ts'ebetsong ea EAF.
- Ho feta moo, maano a China a ho sebetsana le tšilafalo ea moea a matlafalitsoe ke lithibelo tse matla tsa phepelo bakeng sa, eseng feela lekala la tšepe, empa le mafapha a mashala, zinki le a mang a hlahisang tšilafalo e itseng. Ka lebaka leo, tlhahiso ea tšepe ea Chaena e fokotsehile haholo lilemong tse fetileng.

- Lintlha tsohle tse boletsoeng ka holimo, li lebelletsoe ho tsamaisa 'maraka oa li-electrode tsa graphite nakong ea kemiso.
Sebaka sa Asia-Pacific ho laola 'maraka
- Sebaka sa Asia-Pacific se ne se laola karolo ea 'maraka oa lefatše. China e nka karolo e kholo ka ho fetisisa mabapi le tšebeliso le bokhoni ba tlhahiso ea li-electrode tsa graphite maemong a lefats'e.

Melao e joalo e tšehelitse phetoho ea bahlahisi ho tloha mekhoeng e tloaelehileng ea tlhahiso ea tšepe ho ea ho mokhoa oa EAF.
- Tlhahiso e ntseng e hola ea likoloi, hammoho le indasteri e ntseng e hola ea kaho ea bolulo, e lebelletsoe ho ts'ehetsa tlhoko ea lehae ea li-alloys tse senang ferrous le tšepe le tšepe, e leng ntlha e ntle bakeng sa kholo ea tlhokahalo ea li-electrode tsa graphite lilemong tse tlang.
- Bokhoni ba hona joale ba tlhahiso ea li-electrode tsa graphite tsa UHP naheng ea China ke lithane tse likete tse 50 ka selemo. Tlhokahalo ea li-electrode tsa UHP naheng ea China e boetse e lebelletsoe ho paka kholo e kholo nakong e telele mme matla a eketsehileng a lithane tse fetang likete tse 50 tsa li-electrode tsa UHP graphite e lebelletsoe ho bonoa ke mekhahlelo ea morao-rao ea nako ea bolepi.
- Lintlha tsohle tse boletsoeng ka holimo li lebelletsoe ho eketsa tlhoko ea li-electrode tsa graphite sebakeng seo nakong ea kemiso.
