Lihlahisoa tsa graphite li sebelisoa haholo

Graphite ke thepa e feto-fetohang e nang le mefuta e mengata ea ts'ebeliso le melemo, haholo-holo tlhahisong ea thepa e hanyetsang. Lintho tse hanelang ke tsa bohlokoa liindastering tse kang ho etsa tšepe, moo li sebelisetsoang ho kenya liontong, libotong le hlobo, hammoho le tlhahisong ea thepa e hanelang mocheso o phahameng. Indasteri ea lintho tse hanelang e bile le liphetoho tse kholo lilemong tsa morao tjena, ho kenyeletsoa le tšebeliso e pharaletseng ea litene tsa khabone ea magnesia le litene tsa khabone ea aluminium, tseo ka bobeli li amanang haufi-ufi le indasteri ea ho etsa tšepe.

E 'ngoe ea mekhoa e meholo ea graphite ke tlhahisong ea thepa e hanyetsang. Graphite ke karolo ea bohlokoa tlhahisong ea litene tse hanyetsang, lithupa tse besitsoeng, phofo e tsoelang pele ea ho betla, li-cores, hlobo, sesepa, thepa e hanelang mocheso o phahameng, jj. Lisebelisoa tsena li bapala karolo ea bohlokoa lits'ebetsong tse fapaneng tsa indasteri, haholo-holo indastering ea ho etsa tšepe. Hoo e ka bang 10% ea lisebelisoa tse hanyetsang lefats'e li jeoa ke indasteri ea ho etsa tšepe, e leng se totobatsang tšusumetso e kholo ea li-refractories tsa graphite indastering ena.

Tšebeliso e atileng ea litene tsa khabone tsa magnesia liphahlong tsa sebōpi sa tšepe ke e 'ngoe ea liphetoho tsa bohlokoa indastering ea ho hanyetsa mocheso lilemong tsa morao tjena. Li na le motsoako oa magnesium oxide le khabone, litene tsena li na le khanyetso e ntle ea mocheso 'me li tšoarella haholo, e leng se etsang hore li be ntle bakeng sa lifono tsa ho etsa tšepe. Ho phaella moo, tšebeliso ea litene tsa khabone tsa aluminium ho lahla ka mokhoa o tsoelang pele le eona e bone nts'etsopele e kholo. Litene tsena tse nang le aluminium le khabone li ipakile li sebetsa ts'ebetsong ea ho lahla ka mokhoa o tsoelang pele, li bontša ho tenyetseha le ho ikamahanya le maemo ha thepa ea ho hanyetsa graphite.

Lisebelisoa tse hanyetsang graphite li amana haufi-ufi le indasteri ea ho etsa tšepe, 'me tšebeliso le melemo ea tsona li bonahala likarolong tsohle tsa tlhahiso ea tšepe. Bokhoni ba graphite ba ho mamella mocheso o phahameng le maemo a thata bo etsa hore e be thepa e loketseng bakeng sa lionto tsa ho kenya le lisebelisoa tse ling tsa ho etsa tšepe. Ho tšoarella le ho hanyetsa mocheso ha li-refractories tsa graphite ho thusa ho ntlafatsa bokhoni le ts'epo ea ts'ebetso ea tlhahiso ea tšepe, qetellong ho ama boleng le botsitso ba sehlahisoa sa ho qetela.

Ntle le tšebeliso ea eona indastering ea ho etsa tšepe, graphite e na le melemo e 'maloa e le thepa e hanyetsang. E 'ngoe ea melemo ea eona e meholo ke ho khanna ha eona mocheso o phahameng, e leng se nolofalletsang phetiso le kabo e sebetsang hantle ea mocheso lits'ebetsong tsa indasteri. Thepa ena e molemo haholo lits'ebetsong moo mocheso o phahameng o tsitsitseng o lokelang ho bolokoa, joalo ka tlhahisong ea tšepe le thepa e 'ngoe ea mocheso o phahameng.

Ho phaella moo, thepa e hanyetsang graphite e bonts'a botsitso bo botle ba lik'hemik'hale, e leng se etsang hore e hanele mafome le lik'hemik'hale maemong a mocheso o phahameng. Libakeng tse nang le lik'hemik'hale tse matla le litšepe tse qhibilihisitsoeng khafetsa, tšobotsi ena ke ea bohlokoa kaha e netefatsa hore thepa e hanyetsang e phela nako e telele le ho tšepahala.

Molemo o mong oa lihlahisoa tsa graphite ke bokhoni ba tsona ba ho mamella ho thothomela ha mocheso, phetoho ea tšohanyetso mochesong e ka etsang hore thepa e petsohe kapa e hlolehe. Bokhoni ba graphite ba ho mamella ho thothomela ha mocheso bo etsa hore e be khetho e tšepahalang bakeng sa lits'ebetso moo mocheso o fetohang ka potlako, joalo ka indastering ea ho etsa tšepe le ea ho lahla tšepe.

Ho phaella moo, di-refractories tsa graphite di tsebahala ka ho ba le masoba a tlase, e leng se thusang ho eketsa matla le bokgoni ba tsona ba ho hanela ho kenngwa ke tshepe e qhibilihisitsweng le dintho tse ding. Thepa ena e bohlokwa haholo ditshebedisong moo ho kwala le ho kenya mocheso di leng bohlokwa, kaha e netefatsa botshepehi ba thepa e thibelang ho tjheswa tlasa maemo a feteletseng.

Ho tenyetseha ha dihlahiswa tsa graphite ho feta tshebediso ya tsona indastering ya ho etsa tshepe. Di-refractories tsa graphite di boetse di sebediswa ditshebedisong tse ding tse fapaneng tsa mocheso o phahameng, ho kenyeletswa tlhahiso ya di-ceramic, khalase le thepa e nngwe e hlokang botsitso ba mocheso le ho hanela maemo a thata.

Tšebeliso le melemo ea lihlahisoa tsa graphite tlhahisong ea thepa e hanyetsang ke ea bohlokoa ebile e tebile haholo. Tšebeliso e pharaletseng ea graphite tlhahisong ea litene tse hanyetsang, li-crucible, phofo e tsoelang pele ea ho betla, li-core le thepa e hanelang mocheso o phahameng e totobatsa bohlokoa ba eona lits'ebetsong tse fapaneng tsa indasteri, haholo-holo indastering ea ho etsa tšepe. Lintlafatso tsa morao-rao indastering ea ho hanyetsa, joalo ka ho amoheloa ha litene tsa carbon tsa magnesia le litene tsa carbon tsa aluminium, li totobatsa ho ikamahanya le maemo le katleho ea thepa e hanyetsang graphite. Ka ho khanna ha eona mocheso o phahameng, botsitso ba lik'hemik'hale, ho hanyetsa ho ts'oaroa ha mocheso le ho ba le masoba a tlase, graphite e ntse e le khetho ea pele bakeng sa lits'ebetso tse hlokang thepa e tšepahalang le e tšoarellang ea ho hanyetsa. Ha indasteri e ntse e tsoela pele ho fetoha le ho hloka thepa e sebetsang hantle, lihlahisoa tsa graphite li tla bapala karolo ea bohlokoa ho fihlelleng litlhoko tsena le ho khanna boqapi theknolojing ea thepa e hanyetsang.
