Lihlahisoa tsa graphite li sebelisoa haholo

Graphite ke lisebelisoa tse nang le mekhoa e mengata e nang le mefuta e mengata ea tšebeliso le melemo, haholo-holo tlhahiso ea thepa ea refractory. Li-refractories li bohlokoa liindastering tse kang ho etsa litšepe, moo li sebelisetsoang ho etsa libopi, li-crucibles le hlobo, hammoho le ho hlahisa thepa e sa keneleng mocheso o phahameng. Indasteri ea refractory e bile le liphetoho tse kholo lilemong tsa morao tjena, ho kenyelletsa le tšebeliso e atileng ea litene tsa khabone ea magnesia le litene tsa khabone tsa aluminium, tseo ka bobeli li amanang haholo le indasteri ea ho etsa tšepe.

E 'ngoe ea litšebeliso tse ka sehloohong tsa graphite ke tlhahiso ea lisebelisoa tse refractory. Graphite ke karolo ea bohlokoa ha ho etsoa litene tse refractory, li-crucibles, phofo e tsoelang pele ea ho lahla, li-cores, hlobo, li-detergents, lisebelisoa tse hanyetsanang le mocheso o phahameng, joalo-joalo. Lisebelisoa tsena li phetha karolo ea bohlokoa mekhoeng e sa tšoaneng ea indasteri, haholo-holo indastering ea tšepe. Hoo e ka bang 10% ea lisebelisoa tsa lefats'e tsa refractory li jeoa ke indasteri ea ho etsa litšepe, e totobatsang phello e kholo ea li-graphite refractories indastering ena.

Tšebeliso e atileng ea litene tsa khabone ea magnesia lithakong tsa sebōpi sa tšepe ke e 'ngoe ea liphetoho tsa bohlokoa indastering ea refractory lilemong tsa morao tjena. Li na le motsoako oa magnesium oxide le carbon, litene tsena li na le matla a ho hanyetsa mocheso 'me li tšoarella nako e telele, e leng se etsang hore e be tse loketseng bakeng sa ho kenya libopi tsa ho etsa litšepe. Ho feta moo, ts'ebeliso ea litene tsa khabone ea aluminium ka ho lahla ho tsoelang pele ho boetse ho bone tsoelo-pele e kholo. Litene tsena tse nang le aluminium le k'habone li ipakile li sebetsa ts'ebetsong e tsoelang pele ea ho lahla, ho bonts'a ho feto-fetoha le maemo ha lisebelisoa tsa graphite refractory.

Lisebelisoa tsa graphite refractory li amana haufi-ufi le indasteri ea tšepe, 'me litšebeliso 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 libopi tsa masela le lisebelisoa tse ling tsa ho etsa litšepe. Ho tšoarella le ho hanyetsa mocheso oa li-graphite refractories ho thusa ho ntlafatsa katleho le ho tšepahala ha ts'ebetso ea tlhahiso ea tšepe, qetellong e ama boleng le ho tsitsisa ha sehlahisoa sa ho qetela.

Ntle le ts'ebeliso ea eona indastering ea ho etsa litšepe, graphite e na le melemo e 'maloa e le lisebelisoa tse refractory. E 'ngoe ea melemo ea eona e ka sehloohong ke conductivity ea eona e phahameng ea mocheso, e nolofalletsang ho fetisa mocheso o sebetsang hantle le ho ajoa ha mekhoa ea indasteri. Thepa ena e molemo ka ho khetheha lits'ebetsong moo mocheso o tsitsitseng o tsitsitseng o lokelang ho bolokoa, joalo ka tlhahiso ea tšepe le lisebelisoa tse ling tsa mocheso o phahameng.

Ho feta moo, lisebelisoa tsa graphite refractory li bonts'a botsitso ba lik'hemik'hale tse ntle haholo, li etsa hore li se ke tsa bola le karabelo ea lik'hemik'hale mochesong o phahameng. Libakeng tse pepesehang khafetsa lik'hemik'hale tse thata le litšepe tse qhibilihisitsoeng, tšobotsi ena e bohlokoa kaha e netefatsa bophelo bo bolelele le ho ts'epahala ha thepa ea refractory.

Molemo o mong oa lihlahisoa tsa graphite ke bokhoni ba bona ba ho mamella mocheso oa mocheso, phetoho ea tšohanyetso ea mocheso e ka etsang hore thepa e phunye kapa e hlōlehe. Bokhoni ba Graphite ba ho mamella ho sisinyeha 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 litšepe le litšepe.

Ho feta moo, li-refractories tsa graphite li tsebahala ka porosity ea tsona e tlase, e thusang ho eketsa matla a tsona le bokhoni ba ho hana ho kenella ka tšepe e qhibilihisitsoeng le lintho tse ling. Thepa ena ke ea bohlokoa ka ho khetheha lits'ebetsong moo ho tiisa le ho kenya letsoho ho bohlokoa, kaha ho tiisa botšepehi ba thepa ea refractory tlas'a maemo a feteletseng.

Ho feto-fetoha ha lihlahisoa tsa graphite ho fetela ka nģ'ane ho tšebeliso ea eona indastering ea ho etsa litšepe. Li-refractories tsa graphite li boetse li sebelisoa mefuteng e meng e fapaneng ea mocheso o phahameng, ho kenyelletsa le tlhahiso ea li-ceramics, likhalase le lisebelisoa tse ling tse hlokang botsitso ba mocheso le ho hanyetsa maemo a thata.

ts'ebeliso le melemo ea lihlahisoa tsa graphite tlhahisong ea lisebelisoa tsa refractory li bohlokoa ebile li fihla hole. Tšebeliso e atileng ea graphite ha ho etsoa litene tse refractory, li-crucibles, phofo e tsoelang pele ea ho lahla, li-cores le lisebelisoa tse hanyetsanang le mocheso o phahameng li totobatsa bohlokoa ba eona lits'ebetsong tse fapaneng tsa indasteri, haholo-holo indastering ea tšepe. Lintlafatso tsa morao-rao indastering ea refractory, joalo ka ho amoheloa ha litene tsa khabone tsa magnesia le litene tsa khabone tsa aluminium, li totobatsa ho feto-fetoha le katleho ea lisebelisoa tsa graphite refractory. Ka conductivity ea eona e phahameng ea mocheso, botsitso ba lik'hemik'hale, ho hanyetsa mocheso oa mocheso le porosity e tlaase, graphite e ntse e le khetho ea pele bakeng sa likopo tse hlokang lisebelisoa tse ka tšeptjoang le tse tšoarellang tsa refractory. Ha indasteri e ntse e tsoela pele ho fetoha le tlhokahalo ea lisebelisoa tse sebetsang hantle haholo, lihlahisoa tsa graphite li tla bapala karolo ea bohlokoa ho fihlela litlhoko tsena le ho khanna boqapi ho theknoloji ea thepa ea refractory.
