Litšenyehelo tse Phahameng tsa Thepa e Tala
Lisebelisoa tse tala tsa mantlha bakeng sa li-electrode tsa graphite tse nang le matla a phahameng haholo ke needle coke le petroleum coke, 'me needle coke ke karolo ea bohlokoa. Needle coke e na le sebopeho sa fibrous, coefficient e tlase ea katoloso ea mocheso, le bonolo ba graphitization, e leng se etsang hore e be thepa e loketseng bakeng sa ho etsa li-electrode tsa graphite tse nang le matla a phahameng kapa tse nang le matla a phahameng haholo. Leha ho le joalo, ts'ebetso ea eona ea tlhahiso e rarahane, e na le litšitiso tse phahameng tsa tekheniki, 'me phepelo ea lefats'e e ntse e lekanyelitsoe, e leng se fellang ka litheko tse phahameng tse sa khaotseng. Ho feta moo, petroleum coke, e leng thepa e 'ngoe ea bohlokoa e tala, e susumetsoa ke matla a phepelo ea' maraka le ho feto-fetoha ha theko ea oli e tala, ka litheko tse ntseng li nyoloha lilemong tsa morao tjena. Litšenyehelo tsena tse ntseng li eketseha tsa thepa e tala li phahamisa ka kotloloho litšenyehelo tsa tlhahiso ea li-electrode tsa graphite tse nang le matla a phahameng haholo. -
Mekhoa e Rarahaneng ea Tlhahiso
Tlhahiso ea li-electrode tsa graphite tse matla haholo li kenyelletsa mekhahlelo e mengata, ho kenyeletsoa ho calcination ea thepa e tala, ho kopanya, ho bopa, ho baka, ho kenngoa ka har'a moroto, ho kenngoa ka graphitization le ho sebetsa ka machining. Mohato o mong le o mong o hloka taolo e thata ea liparamente tsa ts'ebetso ho netefatsa boleng ba sehlahisoa. Ho kenngoa ka graphitization, mohato oa bohlokoa, ho hloka kalafo mochesong o fetang 2,000°C ho fetola sebopeho sa thepa ea khabone hore e be likristale tsa graphite, ho ntlafatsa ho tsamaisoa ha motlakase le ho hanyetsa mocheso o phahameng. Ts'ebetso ena ha e hloke matla feela empa hape e hloka matsete a maholo a lichelete lisebelisoa, e leng se eketsang litšenyehelo tsa tlhahiso. -
Melemo ea Bohlokoa ea Tshebetso
Li-electrode tsa graphite tse nang le matla a phahameng haholo li bontša thepa e ikhethang, joalo ka ho hanyetsa ka tlase, ho ba le bongata bo phahameng, ho hanyetsa oxidation, mamello ea mocheso o phahameng, le tšebeliso e tlase. Hangata ho hanyetsa ha tsona ho oela ka har'a 4-6 μΩ·m, e leng se nolofalletsang ho tsamaisoa ha hona joale ka liontong tsa arc tsa motlakase ho hlahisa mocheso o lekaneng bakeng sa ho qhibiliha le ho hloekisa tšepe. Ha li bapisoa le li-electrode tsa graphite tse tloaelehileng tsa matla le tse nang le matla a phahameng, mefuta e fapaneng ea matla a phahameng haholo e ka mamella ho ba le matla a holimo a hona joale, e fokotsa nako ea ho qhibiliha ha tšepe e senyehileng, e fokotsa tšebeliso ea motlakase, le ho ntlafatsa katleho ea tlhahiso. Melemo ena ea ts'ebetso e susumetsa ho amoheloa ha tsona ka bophara ho etseng tšepe, tlhahiso ea phosphorus e mosehla, ho qhibilihisa silicon ea indasteri le mafapha a mang, e leng se matlafatsang tlhoko e matla ea 'maraka. -
Matla a Tlhoko ea Phepelo
Lilemong tsa morao tjena, ho tsosolosoa ha indasteri ea tšepe ea lefats'e le kholo e potlakileng mafapheng a macha a matla le a tsoetseng pele a thepa ho hlohlellelitse tlhoko e ntseng e eketseha ea li-electrode tsa graphite tse nang le matla a mangata haholo. Leha ho le joalo, ka lebaka la phepelo e fokolang ea thepa e tala le lits'ebetso tse rarahaneng tsa tlhahiso, kholo ea tlhahiso e bile butle, e eketsa tsitsipano ea tlhoko ea phepelo. Khahlanong le semelo sena, litheko tsa li-electrode tsa graphite tse nang le matla a mangata haholo li eketsehile ka tlhaho.
