Kenyelletso ea Graphite Crucibles

Silicon Carbide Graphite Crucible

Li-crucible tsa graphiteho ba le conductivity e ntle ea mocheso le ho hanyetsa mocheso o phahameng. Nakong ea tšebeliso ea mocheso o phahameng, coefficient ea bona ea ho atolosa mocheso e nyenyane, 'me ba na le khatello e itseng ea ho hanyetsa ho futhumatsa le ho pholile ka potlako. Ho hanyetsa kutu ho matla ho litharollo tsa asiti le alkaline, tse nang le botsitso bo botle ba lik'hemik'hale.

Litšobotsi tsa lihlahisoa tsa graphite crucible
1. Matsete a tlaase, li-graphite crucibles li theko e tlaase ho 40% ho feta libōpi tse tšoanang.
2. Basebedisi ha ba hloke ho etsa sebōpi sa crucible, mme lefapha la rona la khoebo le fana ka sete e feletseng ea moralo le tlhahiso.
3. Tšebeliso e tlaase ea matla, ka lebaka la moralo o utloahalang, mohaho o tsoetseng pele, lisebelisoa tsa libuka, le tšebeliso ea matla e lekiloeng ea li-crucible tsa graphite ha li bapisoa le libōpi tse tšoanang tsa mohlala o tšoanang.
4. Tšilafalo e fokolang, kaha matla a hloekileng a kang khase ea tlhaho kapa khase e entsoeng ka metsi a ka sebelisoa e le mafura, a bakang tšilafalo e fokolang.
5. Ts'ebetso e bonolo le taolo, hafeela valve e fetoloa ho latela mocheso oa sebōpi.
6. Boleng ba sehlahisoa bo phahame, 'me ka lebaka la ts'ebetso le taolo e bonolo, le tikoloho e ntle ea ts'ebetso, boleng ba sehlahisoa bo tiisitsoe.
7. Matla a na le mefuta e mengata ea lisebelisoa, e ka sebelisoang haholo bakeng sa khase ea tlhaho, khase ea mashala, khase e nang le liquefied, oli e boima, diesel, joalo-joalo E ka boela ea sebelisoa bakeng sa mashala le coke ka mor'a phetoho e bonolo.
8.Sebōpi sa graphite crucible se na le mefuta e mengata ea mocheso oa mocheso, o ka qhibilihang, oa kenngoa, kapa ka bobeli o ka sebelisoa hammoho.

Ts'ebetso ea tekheniki ea graphite crucible:

1. Mocheso oa mocheso oa sebōpi 300-1000
2. Matla a ho qhibiliha a crucible (e thehiloeng ho aluminium) a tloha ho 30kg ho ea ho 560kg.
3. Ho hlahisa mafura le mocheso: lik'hilojule tse 8600 / m2 tsa khase ea tlhaho.
4. Tšebeliso e kholo ea mafura bakeng sa aluminium e qhibilihisitsoeng: 0,1 khase ea tlhaho ka kilogram ea aluminium.
5. Nako ea ho qhibiliha: 35-150 metsotso.

E loketse ho qhibilihisa litšepe tse fapaneng tse se nang ferrous joalo ka khauta, silevera, koporo, aluminium, lead, zinki, hammoho le tšepe ea khabone e mahareng le litšepe tse fapaneng tse sa tloaelehang.
Ts'ebetso ea 'mele: Ho hanyetsa mollo ≥ 16500C; Ho bonahala porosity ≤ 30%; Boima ba molumo ≥ 1.7g / cm3; Matla a ho hatella ≥ 8.5MPa
Sebopeho sa lik'hemik'hale: C: 20-45%; SIC: 1-40%; AL2O3: 2-20%; SIO2: 3-38%
Sekoti se seng le se seng se emela kilogram e le 1 ea koporo e qhibilihisitsoeng.

Morero oa graphite crucible:
Graphite crucible ke sekepe se refractory se entsoeng ka graphite ea tlhaho ea flake, lejoe la boka, silicon carbide le lisebelisoa tse ling tse tala, tse sebelisetsoang ho qhibilihisa le ho lahlela koporo, aluminium, zinki, lead, khauta, silevera le mefuta e sa tšoaneng ea tšepe e sa tloaelehang.

Litaelo tsa ho sebelisa lihlahisoa tsa crucible
1. Nomoro e hlalositsoeng ea crucible ke bokhoni ba koporo (#/kg)
2. Li-crucible tsa graphite li lokela ho bolokoa hole le mongobo 'me li lokela ho bolokoa sebakeng se omileng kapa holim'a foreimi ea lepolanka.
3. Tšoara ka hloko nakong ea lipalangoang 'me u thibele ka tieo ho oela kapa ho sisinyeha.
4. Pele o sebelisoa, ho hlokahala hore u chese bake ka thepa ea ho omisa kapa ka sebōpi, 'me mocheso o nyolohela ho 500 ℃ butle-butle.
5. The crucible e lokela ho behoa ka tlas'a holim'a molomo oa sebōpi ho qoba ho senya le ho senya sekoahelo sa sebōpi.
6. Ha o eketsa lisebelisoa, e lokela ho thehoa holim'a solubility ea crucible, 'me boitsebiso bo bongata haholo ha boa lokela ho kenngoa ho qoba ho atolosoa ha crucible.
7. Sesebelisoa sa ho lahla le clamp ea crucible e lokela ho lumellana le sebōpeho sa crucible, 'me karolo e bohareng e lokela ho kenngoa ho qoba tšenyo ea matla a sebaka ho crucible.
8. Ha u tlosa slag le coke marakong a ka hare le a ka ntle a crucible, e lokela ho kokota ka bonolo ho qoba ho senya crucible.
9. Sebaka se loketseng se lokela ho bolokoa pakeng tsa crucible le lerako la sebōpi, 'me crucible e lokela ho behoa bohareng ba sebōpi.
10. Tšebeliso ea lithuso tse feteletseng tsa mollo le li-additives li tla fokotsa bophelo ba tšebeletso ea crucible.
11. Nakong ea tšebeliso, ho potoloha crucible hang ka beke ho ka eketsa bophelo ba eona ba tšebeletso.
12. Qoba ho fafatsa ka ho toba malakabe a matla a oxidation ka mahlakoreng le tlase ho crucible.
