E le sesebelisoa sa bohlokoa liindastering tse kang ho qhibilihisa tšepe le lisebelisoa tse ling tsa mocheso o phahameng, li-graphite crucibles li bapala karolo ea bohlokoa ho kenya le ho futhumatsa litšepe tse fapaneng le li-alloys. Leha ho le joalo, bophelo ba bona ba litšebeletso bo ne bo lekanyelitsoe, hoo ho ka ba khathatso 'me ho fella ka litšenyehelo tse eketsehileng bakeng sa basebelisi. Sehloohong sena, re tla hlahloba mekhoa e tšoanang ea ho eketsa nako ea bophelo ea li-crucible tsa graphite le ho lelefatsa nako e telele ea tsona.
Li-crucible tsa graphite li sebelisoa haholo bakeng sa lits'ebetso tsa ho qhibiliha le ho lahla, ka lebaka la ts'ebetso ea tsona e ikhethang ea mocheso, ho hanyetsa kutu le thepa ea refractory. Leha ho le joalo, bophelo ba bona bo bolelele bo itšetlehile ka lintlha tse 'maloa, tse kang boleng ba thepa e tala, mekhoa ea tlhahiso, maemo a ts'ebetso le mekhoa ea tlhokomelo. Ka hona, ho bohlokoa ho khetha li-crucible tsa boleng bo holimo ho tsoa ho barekisi ba tšepahalang le ho latela litataiso tse khothaletsoang bakeng sa ts'ebeliso le tlhokomelo ea bona.
Ntlha e 'ngoe ea bohlokoa e amang nako ea bophelo ea li-crucible tsa graphite ke mokhoa oa ho futhumatsa le ho pholisa. Liphetoho tse potlakileng tsa mocheso, tse tsejoang hape e le ho tšoha ha mocheso, li ka lebisa ho phunyeha, ho senya, kapa ho senyeha ha li-crucibles, qetellong ho fokotsa nako e telele le katleho ea tsona. E le ho qoba litaba tsena, ho kgothaletswa hore butle-butle le ka mokhoa o ts'oanang o chese li-crucibles pele o eketsa tšepe kapa li-alloys ebe o li pholile butle-butle ka mor'a hore ts'ebetso e phethe.
Ntho e 'ngoe ea bohlokoa e lokelang ho nahanoa, e leng mofuta oa tšepe kapa alloy e ntseng e sebetsoa. Litšepe tse ling, tse kang tšepe, nickel le cobalt, li ka sebetsanoa le graphite ka mocheso o phahameng le ho etsa li-carbides, tse ka potlakisang ho senyeha ha li-crucibles. E le ho qoba sena, ho eletsoa ho sebelisa liaparo tse sireletsang kapa li-liner holim'a li-crucibles kapa ho khetha limaraka tse khethehileng tsa graphite tse hanyetsanang le liketso tse joalo.
Ho feta moo, tlhokomelo e nepahetseng le ho hloekisoa ha li-crucible le tsona li bohlokoa ho lelefatsa bophelo ba tsona le ho thibela tšilafalo ea litšepe kapa li-alloys. Ho kgothaletswa ho tlosa, ho pholile le ho hloekisa li-crucibles ka mor'a ts'ebeliso e 'ngoe le e' ngoe ho sebelisa lisebelisoa le lik'hemik'hale tse loketseng ho felisa mesaletsa leha e le efe kapa litšila. Ho boloka li-crucible hantle sebakeng se omeletseng le se sireletsehileng ho boetse ho bohlokoa ho thibela tšenyo ea 'mele kapa ho kenngoa ha mongobo.
Ho akaretsa, ho eketsa nako ea bophelo ba li-graphite crucibles ho hloka ho khomarela mekhoa le litemoso tse nepahetseng. Sena se kenyelletsa ho khetha li-crucible tsa boleng bo holimo, ho li tšoara ka hloko, ho laola mokhoa oa ho futhumatsa le ho pholisa, ho li sireletsa litšepeng tse sebetsang hantle, le ho li boloka kamehla. Ka ho etsa joalo, basebelisi ba ka boloka nako, chelete le lisebelisoa ha ba ntse ba netefatsa ts'ebetso ea crucible e tsitsitseng le e tšepahalang.
