Li-crucible tsa graphiteke lisebelisoa tse fapaneng le tsa bohlokoa liindastering tse fapaneng ho kenyelletsa metallurgy, k'hemistri le ho etsa mabenyane. E etselitsoe ho mamella mocheso o phahameng haholo 'me hangata e sebelisetsoa ho qhibiliha, ho lahla le ho qhibilihisa mefuta e fapaneng ea thepa. Haeba u sa tsoa qala ho sebelisa li-graphite crucibles, kapa u batla ho ntlafatsa mokhoa oa hau, tataiso ena e tla u tsamaisa mohato ka mohato, ho etsa bonnete ba hore u itokisitse ka botlalo 'me u itokiselitse katleho.
1. Khetha crucible e nepahetseng ea graphite:
Ho khetha crucible e nepahetseng ea graphite ho bohlokoa ho fumana litholoana tse ntle. Nahana ka lisebelisoa tseo u tla li sebelisa le mefuta e fapaneng ea mocheso e hlokahalang. Li-crucibles tse fapaneng li etselitsoe ho sebetsana le mocheso le lisebelisoa tse itseng, tse kang khauta, silevera kapa esita le graphite. Etsa bonnete ba hore u khetha crucible e nepahetseng bakeng sa kopo ea hau e khethehileng.
2. Lokisetsa crucible:
Pele o qala ho sebelisa graphite crucible ea hau, ke habohlokoa ho e lokisetsa hantle hore e sebelisoe. Sena ke sa bohlokoa kaha se thusa ho tlosa litšila leha e le life le ho netefatsa nako e telele ea crucible. Qala ka ho hloekisa ka bonolo ka hare ho crucible ho sebelisa borashe kapa lesela le bonolo ho tlosa likaroloana tse hlephileng. Qoba ho sebelisa lintho tse chefo tse ka 'nang tsa ngoapa kapa tsa senya bokaholimo ba graphite. Hlatsoa crucible ka metsi a hloekileng 'me u lumelle moea hore o ome.
3. Sebelisa crucible coating:
Ho lelefatsa bophelo ba tšebeletso ea graphite crucible ea hau le ho sireletsa bokaholimo ba eona bo ka hare, ho kgothaletswa ho etsa kopo ya ho roala. Ho ka sebelisoa seaparo sa refractory kapa motsoako oa graphite le borax. Hlakola karolo e tšesaane ea motsoako oa ho roala ka har'a bokaholimo ba crucible, ho etsa bonnete ba hore e koahela sebaka sohle. Lera lena le sireletsang le fokotsa kotsi ea hore thepa e qhibilihisitsoeng e sebetsane le bokahare ba graphite ba crucible.
4. Preheat crucible:
Ho futhumatsa graphite crucible ea hau ho bohlokoa ho thibela ts'oaetso ea mocheso le tšenyo e ka bang teng nakong ea ho qhibiliha. Beha crucible ka sebōping se se nang letho kapa sebōpi 'me butle-butle u eketse mocheso ho ea boemong ba eona ba ho sebetsa. Ho futhumatsa hona butle-butle ho lumella crucible hore e atolohe ka ho lekana, ho fokotsa kotsi ea ho robeha. Etsa bonnete ba hore u sheba litataiso tsa moetsi bakeng sa litaelo tse tobileng tsa ho futhumatsa.
5. Ho qhibiliha ka crucible ea graphite:
Hang ha crucible e se e loketse, u ka qala ho qhibilihisa thepa. Etsa bonnete ba hore crucible e behiloe ka mokhoa o sireletsehileng ka har'a sebōpi ho netefatsa botsitso le ho thibela likotsi leha e le life. Latela litaelo tse tobileng tsa ho qhibiliha bakeng sa thepa eo u e sebelisang (ebang ke tšepe e kopantsoeng, khalase, kapa lisebelisoa tse ling) ho finyella liphello tse lakatsehang.
6. Tlhokomelo le polokeho ea crucible:
Tlhokomelo e nepahetseng ea li-crucible tsa graphite ke ea bohlokoa bakeng sa ts'ebetso e nepahetseng le bophelo ba tšebeletso. Hloekisa masalla kapa lintho tse setseng ka botlalo ka mor'a tšebeliso e 'ngoe le e 'ngoe. Qoba ho pepesa crucible liphetohong tse potlakileng tsa mocheso kaha sena se ka baka ts'oenyeho ea mocheso le tšenyo. Ho phaella moo, kamehla u etelletse pele tšireletseho 'me u apare lisebelisoa tse loketseng tsa ho itšireletsa, ho akarelletsa le liatlana tse thibelang mocheso le likhalase, ho itšireletsa likotsing tse ka 'nang tsa u hlahela.
Ka kakaretso, ho lokisetsa graphite crucible ho hloka ho nahanisisoa ka hloko le mokhoa o nepahetseng. Ka ho khetha crucible e nepahetseng, ho lokisa crucible ka nepo, le ho latela mekhoa e khothalletsoang ea ho qhibiliha, u ka etsa bonnete ba hore sephetho se atlehileng le se sebetsang hantle. Hopola ho beha polokeho pele le ho boloka crucible ea hau khafetsa ho lelefatsa bophelo ba eona. Ka mehato ena kelellong, u tla be u itokiselitse hantle ho sebelisa graphite crucible ea hau ka katleho le ho eketsa bokhoni ba eona mefuteng e fapaneng ea lisebelisoa.
