Boholo ba crucible

Likarolo tsa Bohlokoa tsa Silicon Carbide Crucibles ea rona

1. Lisebelisoa le Sebopeho:
   • Ea ronaLithako tsa Silicon Carbideli entsoe ka mekhoa ea boleng bo holimo ea silicon carbide bonding. Tshebetso ya carbon bonding e matlafatsa sebopeho sa crucible, e etsa hore e be e loketseng bakeng sa ditshebediso tsa mocheso o phahameng.
   • Ho kopanngoa ha letsopa la silicon carbide le silicon carbide graphite ho netefatsa hore ho na le conductivity e ntle ea mocheso le ho tšoarella, ho etsa hore e tšoanelehe bakeng sa mekhoa e sa tšoaneng ea ho qhibiliha.
2. Mehato ea ho futhumatsa pele:
   • Preheating e nepahetseng eaSilicon Carbide Crucibleho bohlokoa ho thibela litaba tse kang ho atolosoa ha mocheso, ho arohana, delamination, kapa ho phunyeha ho bakoang ke mongobo o setseng. Mona ke kamoo o ka lokisang li-crucible tsa hau hantle:
     • Pele Baking: Bake crucible ka ontong ntle le lisebelisoa bakeng sa ho fetaLihora tse 24, ho e potoloha kamehla ho netefatsa hore esita le ho futhumatsa le ho tlosoa ha mongobo.
     • Ho futhumatsa butle-butle: Preheat to150-200 ° Cbakeng sa1 hora, ebe o eketsa mocheso ka sekhahla sa150 ° C ka hora, ho qoba ho pepesehela nako e telele mocheso pakeng tsa315-650°Cho thibela oxidation.
     • Phekolo ea Mocheso o Phahameng: Ka mor'a preheating ea pele, ka potlako eketsa mocheso ho850-950°Cbakeng saMetsotso e 30pele o eketsa lisebelisoa. Kalafo ena e eketsa haholo bophelo ba tšebeletso ea crucible.
3. Litlhaloso (Ka tloaelo):
   • Ea ronaLithako tsa Silicon Carbidee ka etsoa ka boholo le boholo ho lumellana le litlhoko tsa hau tse khethehileng tsa ho qhibiliha. Ikopanye le rona bakeng sa litharollo tse hlophisitsoeng tse fihlelang litlhoko tsa hau tsa tlhahiso.

Melemo le Tshebetso

• Thermal Stability: Tsa ronaCarbon Bonded Silicon Carbide Cruciblesboloka botšepehi ba sebopeho mochesong o phahameng, ho etsa bonnete ba ho qhibiliha ka katleho ntle le deformation.
• Khanyetso ea Corrosion: Thepa ea tlhaho ea Silicon carbide e fana ka khanyetso e ntle ea ho bola ha lik'hemik'hale, e leng bohlokoa bakeng sa ho boloka boleng ba litšepe tse qhibilihisitsoeng le ho lelefatsa bophelo ba crucible.
• Thermal Conductivity: Ka conductivity e phahameng ea mocheso, li-crucibles tsena li khothalletsa ho futhumala ho tšoanang, ho matlafatsa ts'ebetso ea ts'ebetso ea ho qhibiliha le ho ntlafatsa tlhahiso ea kakaretso ea tlhahiso.
• Matla a Mechini: E etselitsoe ho mamella meroalo e boima le likhatello tse phahameng, li-crucibles tsa rona li ithorisa ka matla a makatsang a mochini, li li etsa tse loketseng lits'ebetso tse hlokang.

Libaka tsa Kopo

Ea ronaLithako tsa Silicon Carbideli sebelisoa haholo liindastering tse fapaneng, ho kenyelletsa:

• Aluminium le Metal Melting: E nepahetse bakeng sa ts'ebetso ea ho qhibilihisa, li-crucibles tsa rona li netefatsa bohloeki bo phahameng ba litšepe ha li ntse li ntlafatsa linako tsa ho qhibiliha.
• Bathehi: E bohlokoa bakeng sa lits'ebetso tsa ho lahla, ho fana ka tikoloho e tšepahalang bakeng sa tlhahiso ea likarolo tsa boleng bo holimo.
• Lilaboratori tsa Lipatlisiso: E loketse liteko tsa mocheso o phahameng, ho netefatsa ho nepahala le ho tšepahala litekong tsa thepa.

Ea ronaLithako tsa Silicon Carbideemela tlhōrō ea ts'ebetso le botšepehi indastering ea ho qhibiliha ha tšepe. Ka ho kenyelletsa lisebelisoa tse tsoetseng pele le mekhoa e hlokolosi ea ho futhumatsa pele, re fana ka litharollo tse ntlafatsang ts'ebetso, ho lelefatsa bophelo ba ts'ebeletso, le ho ntlafatsa tlhahiso. Bakeng sa litsebi tsa likarolo tsa motheo le tsa metallurgical, ho khetha li-crucibles tsa rona ke mohato o lebisang ho finyella katleho e phahameng le boleng bo phahameng ba sehlahisoa. Bakeng sa lintlha tse ling kapa ho buisana ka litlhoko tsa hau tse khethehileng, ka kopo u se ke ua qeaqea ho iteanya le rona.
