Lintlha tsa Bohlokoa tsa Melting Crucibles ea Rōna

1. Lisebelisoa tsa Crucible:
   • Lithako tsa Silicon Carbide: Li tsejoa ka mokhoa oa tsona o motle oa ho tsamaisa mocheso, li-crucible tsena li ka sebetsa ka katleho mocheso ho fihlela1700°C, e fetang hōle sebaka se qhibilihang sa aluminium (660.37°C). Sebopeho sa bona se phahameng se fana ka matla a tsotehang le ho hanyetsa deformation.
   • Li-crucibles tse entsoeng ka Silicon Carbide: Phetolelo e ntlafalitsoeng e sebetsanang le bofokoli bo tloaelehileng bo fumanoang ho li-crucibles tsa setso, joalo ka matla a tlase le ho hanyetsa mocheso o fokolang. Li-crucibles tsena li sebelisa motsoako oa carbon fiber le silicon carbide, ho netefatsa ts'ebetso e phahameng.
2. Lintho tse Molemohali tsa Crucible:
   • Li-crucible tsa rona tsa silicon carbide li fana ka litšobotsi tse ikhethang, ho kenyelletsa:
     • Melting Point: Ho fihlela2700°C, e loketseng lits'ebetso tse fapaneng tsa mocheso o phahameng.
     • Botenya: 3.21 g/cm³, e tlatsetsang matleng a tsona a matla a mochine.
     • Thermal Conductivity: 120 W/m·K, e nolofalletsang kabo ea mocheso e potlakileng le e ts'oanang bakeng sa ts'ebetso e ntlafetseng ea ho qhibiliha.
     • Mocheso oa Katoloso ea Mocheso: 4.0 × 10⁻⁶/°Csebakeng sa 20-1000 ° C, ho fokotsa khatello ea mocheso.
3. Crucible Temperature Range:
   • Li-crucibles tsa rona li etselitsoe ho mamella mocheso oa mocheso oa ho sebetsa oa800°C ho isa ho 2000°Cka hang hang boholo ba mocheso o hanyetsanang le2200°C, ho etsa bonnete ba ho qhibiliha ho sireletsehileng le ka katleho ha litšepe tse fapaneng.

Litlhaloso (Ka tloaelo)

• Phokotso ea Botenya: Li-crucible tsa rona tsa carbonized silicon carbide li entsoe ka ho fokotsa botenya ba30%, ho matlafatsa conductivity ea mocheso ha u ntse u boloka matla.
• Keketseho Matla: Matla a li-crucible tsa rona a eketseha ka50%, e ba nolofalletsang ho mamella khatello e phahameng ea mochine.
• Thermal Shock Resistance: E ntlafalitsoe ke40%, ho fokotsa monyetla oa ho phatloha nakong ea ho futhumatsa le ho pholile ka potlako.

Mokhoa oa Tlhahiso

Mokhoa oa ho etsa li-crucible tsa rona tsa carbonized silicon carbide o kenyelletsa mehato e 'maloa ea bohlokoa:

1. Pōpo ea Preform: Carbon fiber e fetisetsoa pele ho sebopeho se loketseng tlhahiso ea crucible.
2. Carbonization: Mohato ona o theha sebopeho sa pele sa silicon carbide.
3. Densification le Tlhoekiso: carbonization e eketsehileng e eketsa bongata ba thepa le botsitso ba lik'hemik'hale.
4. Silicone: The crucible e qoelisoa ka silicon e qhibilihisitsoeng ho matlafatsa matla a eona le ho hanyetsa kutu.
5. Sebopeho sa ho Qetela: The crucible e bōpehile ho finyella litlhoko tse khethehileng, ho netefatsa ts'ebetso e nepahetseng.

Melemo le Tshebetso

• Matla a Mocheso o Phahameng: Ka bokhoni ba ho boloka botšepehi ba sebopeho ka mocheso o feteletseng, li-crucible tsa rona tsa silicon carbide li netefatsa ho tšepahala nakong ea mekhoa ea ho qhibiliha ha mocheso o phahameng.
• Khanyetso ea Corrosion: Li-crucibles tsena li hanela kutu ho tsoa ho aluminiamo e qhibilihisitsoeng le litšepe tse ling, li lelefatsa bophelo ba tsona haholo le ho fokotsa makhetlo a mangata.
• Inert ea lik'hemik'hale: Silicon carbide ha e sebetsane le aluminium, e netefatsa bohloeki ba tšepe e qhibilihisitsoeng le ho thibela tšilafalo ho tsoa litšila.
• Matla a Mechini: Ka matla a kobehang a400-600 MPa, li-crucibles tsa rona li ka mamella meroalo e boima, e etsang hore e tšoanelehe bakeng sa likopo tse hlokang.

Lisebelisoa

Li-crucibles tse qhibilihang tsa silicon carbide li sebelisoa haholo ho:

• Aluminium Smelting Plants: Bohlokoa bakeng sa ho qhibiliha le ho hloekisa li-ingots tsa aluminium, ho netefatsa lihlahisoa tsa boleng bo phahameng ba aluminium.
• Aluminium Alloy Foundries: Ho fana ka tikoloho e tsitsitseng ea mocheso o phahameng bakeng sa ho lahla likarolo tsa motsoako oa aluminium, ho ntlafatsa boleng ba sehlahisoa le ho fokotsa litheko tsa sekhechana ka30%.
• Lilaboratori le Mekhatlo ea Lipatlisiso: E loketse liteko tsa mocheso o phahameng, ho netefatsa lintlha tse nepahetseng le liphetho tse tšepahalang ka lebaka la ho se sebetse ha lik'hemik'hale le botsitso ba mocheso.

Ea ronali-crucibles tse qhibilihangke lisebelisoa tsa bohlokoa indastering ea ho qaptjoa le ho qhibilihisa tšepe, tse tsejoang ka ts'ebetso ea tsona e ikhethang le ho feto-fetoha ha maemo. Ka ho etelletsa pele boleng le boqapi bo tsoelang pele, re ikemiselitse ho fa bareki ba rona litharollo tsa boleng bo holimo tsa ho qhibiliha tse tsamaellanang le litlhoko tsa bona tse ikhethileng. Haeba u ntse u batla crucible e ka tšeptjoang bakeng sa ts'ebetso ea hau ea ho qhibiliha ha tšepe, u se ke ua sheba hole le li-crucible tsa rona tsa silicon carbide tse etselitsoeng ka nepo le boiphihlelo. Bakeng sa lipotso kapa lintlha tse ling, ka kopo ikutloe u lokolohile ho ikopanya le rona.
