Selelekela: Li-crucible tsa graphite li ka aroloa ka mekhahlelo e mene.
1.E hloekileng graphite crucible.Thekhaboneka kakaretso e kholo ho feta99.9%, 'me e entsoe ka thepa e hloekileng ea graphite ea maiketsetso.Ho kgothaletswa feela ho sebelisa mefuta e meng ea sebōpi ka hloko bakeng salibono tsa motlakase.
2.Clay graphite crucible.E entsoe ka phofo ea tlhaho ea graphite e kopantsoeng le letsopa le lisebelisoa tse ling tse thibelang oxidation, 'me e etsoa ka ho potoloha.E loketse lifeme tse nang le llitšenyehelo tsa mosebetsilesekhahla se tlase sa ts'ebetso.
3.Silicon carbide graphite crucible, e entsoeng ka ho potoloha.E entsoe ka phofo ea tlhaho ea graphite, silicon carbide, aluminium oxide, joalo-joalo e kopantsoe e le lisebelisoa tse tala, e entsoeng ka spin-mold, 'me e eketsoa ka lera la anti-oxidation.Bophelo ba ts'ebeletso bo ka ba makhetlo a 3-8 ho feta a letsopa graphite crucible.Boima ba bongata bo pakeng tsa 1.78-1.9.E loketse bakeng saho qhibilihisa teko ea mocheso o phahameng, tlhokahalo e tsebahalang.
4.The silicon carbide graphite crucible e thehoa ka ho hatella isostatic, 'me crucible e hatelloa ke mochine oa khatiso oa isostatic.Bophelo ba ts'ebeletso hangata bo makhetlo a 2-4 ho feta ba rotary e entsoeng ka silicon carbide graphite crucible.Ke eona e loketseng ka ho fetisisa bakeng saaluminiumlezinki oxide.Litšepe tse ling li lokela ho khethoa ka hloko, 'me libōpi tsa induction li lokela ho khethoa ka hloko.Ka lebaka la litšenyehelo tse phahameng tsa ho hatella isostatic, hangata ha ho na crucible e nyane.

Mefuta ea sebōpi bakeng sa li-crucibles:sebopi sa coke, sebōpi sa oli, sebōpi sa khase ea tlhaho, sebopi sa ho hanyetsa, sebōpi sa maqhubu a mahareng(ka kopo hlokomela hore ts'ebetso ea ho qhibiliha ha aluminium ha e phahame), sebōpi sa likokoana-hloko tsa likokoana-hloko, joalo-joalo E loketse ho qhibilihisa koporo, khauta, silevera, zinki, aluminium, lead, tšepe e entsoeng ka tšepe le lisebelisoa tse ling tse se nang ferrous.Hammoho le acid e seng matla le lik'hemik'hale tse matla tsa alkali tse nang lemetsi a tlase, khanyetso ea kutuleho hanyetsa mocheso o phahameng.
Litaelo tsa tšebeliso ea graphite crucible (ka kopo bala ka hloko pele o sebelisoa):
1.The crucible bolokoa ka ae kenya moealeommetikoloho ho qoba ho angoa ke mongobo.
2. The crucible e lokela ho tšoaroa ka hloko, e thibetsoe ka thata ho theoha le ho sisinyeha, 'me u se ke ua phutha, e le hore u se ke ua senya lera le sireletsang holim'a crucible.
3. Bake crucible esale pele pele o sebelisoa.Mocheso oa ho baka o ntse o eketseha butle-butle ho tloha tlaase ho ea holimo, 'me crucible e lula e fetoloa ho lumella hore e futhumale ka mokhoa o ts'oanang, ho tlosa mongobo ka har'a crucible,' me butle-butle ho eketsa mocheso oa preheating ho feta 500 (joaloka preheating).E sa nepahaleng, e etsang hore crucible e qhekelle ebe e phatloha, ha se bothata ba boleng mme e ke ke ea khutlisoa)
4. Sebōpi sa crucible se lokela ho lumellana le crucible, likheo tse ka holimo le tse ka tlaase le tse potolohileng li lokela ho finyella litlhoko, 'mesekoahelo sa sebōpi ha sea lokela ho hatelloa 'meleng oa crucible.
5. Qoba ente e tobileng ea lelakabe ho 'mele oa crucible nakong ea tšebeliso,' me e lokela ho base fafalitsoeng nqa ya motheo wa crucible.
6. Ha o eketsa boitsebiso, bo lokela ho ekeletsoa butle, ka ho khethehathepa e sithabetseng.U se ke ua phutha lintho tse ngata haholo kapa tse thata haholo, e le hore li se ke tsa phatlola crucible.
7. Lithako tsa crucible tse sebelisetsoang ho laela le ho laolla li lokela ho lumellana le sebōpeho sa crucible, e le hore li se ke tsa senya crucible.
8. Ho molemo hosebelisa crucible kamehla, e le hore e sebelise ts'ebetso ea eona e phahameng hamolemo.
9. Nakong ea ts'ebetso ea ho qhibiliha, palo e kenang eamoemeli o tlameha ho laoloa.Tšebeliso e feteletseng e tla fokotsa bophelo ba tšebeletso ea crucible.
10. Ha u sebelisa crucible,potoloha crucible nako le nakoho etsa hore e futhumale ka ho lekana le ho lelefatsa tshebediso.
11.Tlanya hanyenyaneha u tlosa slag le coke marakong a ka hare le a ka ntle a crucible ho qoba tšenyo ea crucible.
12. Tšebeliso ea solvent bakeng sa graphite crucible:
1) Tlhokomeliso e lokela ho lefshoa ha o eketsa solvent:solvent e lokela ho ekeletsoa ka tšepe e qhibilihisitsoeng, 'me ho thibetsoe ka ho feletseng ho eketsa mokelikeli pitseng e se nang letho kapa pele tšepe e qhibiliha: hlohlelletsa tšepe e qhibilihisitsoeng hang ka mor'a ho eketsa tšepe e qhibilihisitsoeng.
2) Mokhoa oa ho kopanya:
a.Lintho tse qhibilihisang ke phofo, bongata, le metsoako ea tšepe.
b, lebitso la kopo ea bongata le qhibilihisoabohareng ba cruciblelekarolo ea boraro ea boemo bo ka holimo ho bokaholimo bo ka tlase.
c.Phallo e phofshoana e lokela ho ekeletsoa hoqoba ho kopana ka kotloloho le lebota la crucible.d.Ho joaloe thibetsoe ka thata hore phallo e hasane ka seboping se qhibilihang, ho seng joaloe tla senya lerako le kantleea crucible.
e, Chelete e ekelitsoeng kebonyane cheletee boletsoeng ke moetsi.
f.Ka mor'a hore ho eketsoe moemeli oa ho hloekisa le mofetoleli, tšepe e qhibilihisitsoenge lokela ho sebelisoa kapele.
g, netefatsa hore ho sebelisoa phallo e nepahetseng.Khoholeho ea Flux holim'a khoholeho ea graphite crucible Refining modifier: Fluoride e ka har'a sesebelisoa se hloekisitsoeng e tla hohola crucible ho tloha karolong e ka tlase (R) ea lebota le kantle la crucible.
Corrosion: The crucible sticky slag e lokela ho bahloekisoa letsatsi le letsatsiqetellong ya phetoho.Ho senyeha ho sa tsitsang ho tla qoelisoa ka har'a slag le ho hasana ka har'a crucible, ho eketsa kotsi ea ho hloekisa ho senyeha le ho senyeha ha mobu.Mocheso le sekhahla sa kutu: Sekhahla sa karabelo sa crucible le se hloekisang se lekana le mocheso.Ho eketsa mocheso o phahameng o sa hlokahaleng oa mokelikeli oa alloy o tla khutsufatsa haholo bophelo ba crucible.Ho bola ha aluminium molora le slag ea aluminium: Bakeng sa molora oa aluminium o nang le letsoai le tebileng la sodium le letsoai la phosphorus, boemo ba kutu bo tšoana le bo boletsoeng ka holimo, bo tla khutsufatsa haholo bophelo ba crucible.Khoholeho ea mokelikeli o nang le mokelikeli o motle: Ha ho eketsoa sekontiri se nang le mokelikeli o motle, tšepe e qhibilihisitsoeng e lokela ho tsosoa ka potlako e le hore e se ke ea kopana le 'mele oa pitsa.
13. Sesebelisoa sa ho Hloekisa Graphite Crucible Slag Cleaning: Sesebelisoa se pota-potiloe ka sekhahla se tšoanang le lerako le ka hare la pitsa e sebelisitsoeng.Ho tlosoa ha pele: Ka mor'a ho futhumatsa le ho sebelisoa ha pele, ho tlosoa ha slag e hlahisoang ke habohlokoa ka ho fetisisa.Slag e hlahisoang ka lekhetlo la pele e bonolo haholo, empa ka mor'a hore e tlohe, e ba thata haholo 'me ho le thata ho e tlosa.Nako ea ho hloekisa:Le hoja crucible e ntse e chesa 'me slag e le bonolo, e lokela ho hloekisoa letsatsi le leng le le leng.
