Thepa ea 'Mele le ea Lik'hemik'hale eaSic Crucibles
Ha u khetha likhatiso tsa likopo tsa indasteri, ho utloisisa li-indexe tsa lik'hemile le tsa lik'hemileto ho bohlokoa. Ka tlase ke karohano ea thepa ea bohlokoa ea thepa ea ISO Types:
| Thepa ea 'Mele | Index |
|---|---|
| Refractoriness | ≥ 1650°C |
| Porosity e bonahalang | ≤ 20% |
| Boima ba Bongata | ≥ 2.2 g/cm² |
| Matla a Petlang | ≥ 8,5 MPa |
| Sebopeho sa Lik'hemik'hale | Index |
|---|---|
| Khabone (C%) | 20–30% |
| Silicon Carbide (SiC%) | 50–60% |
| Alumina (Al2O3%) | 3–5% |
Litšobotsi tsena li fa Sic Crucibles mokhoa o ikhethang oa ho futhumatsa mocheso, katoloso e tlase ea mocheso, le ho hanyetsa ho bola ha lik'hemik'hale, ho netefatsa hore li sebetsa hantle esita le libakeng tse thata ka ho fetisisa.

Melemo ea Sic Crucibles
- Ho hanyetsana le Mocheso o Phahameng: Li-Chectible tsa maiketsetso li amella mocheso o fihla ho 1650 ° C, o li etsa hore li lokele tšepe le likopo tse ling tsa mocheso.
- Ho tšoarella le ho phela halelele: Ka matla a matla a ho senya a ≥ 8.5 MPa, li-crucibles tsena li ka mamella khatello ea mechine e amehang libakeng tsa indasteri ntle le ho senya kapa ho senya.
- Botsitso ba Lik'hemik'hale: Likahare tse phahameng tsa silicon carbide (50-60%) li fana ka khanyetso e babatsehang ea lik'hemik'hale tsa lik'hemik'hale, ho netefatsa bophelo bo bolelele le ha li pepesehetse litšepe tse qhibilihisitsoeng kapa lik'hemik'hale tse mabifi.

Ho holisa bophelo bo botle ba lintho tse sa tsitsang le ho netefatsa ts'ebetso ea bona e bolokehileng, ho bohlokoa ho latela litapole tse 'maloa tsa tlhokomelo:
- Ho Hloekisa Kamehla: Lits'oants'o li lokela ho hloekisoa khafetsa ho tlosa sekhahla leha e le sefe, tšilafalo le mohahlapetsi.
- Qoba Thermal Shock: Ho futhumatsa khafetsa le ho futhumatsa ho bohlokoa ho thibela ho hlaka. Ho fetoha ha mocheso oa tšohanyetso ho ka etsa hore thepa eo e robehe.
- Thibela ho Corrosion ea Lik'hemik'hale: Qoba ho pepesetsoa lik'hemik'hale tse matla, haholo-holo alkaline kapa tharollo ea acidic, e ka nyenyefatsang botšepehi bo sa tšoaroang habonolo.

Ho khetha se nepahetseng ka mokhoa o nepahetseng ho latela litlhoko tse ikhethang tsa ts'ebetso ea hau ea indasteri. Nahana ka lintlha tse kang mocheso, ho tsamaisa thepa le lintho tse ngata le litlhokahalo tsa boholo. Likopong tsa 'nete tsa lefats'e, bareki ba bangata ba tlalehile ho fokotseha ho hoholo ha litšenyehelo tsa tlhokomelo le ho eketsa katleho ea tlhahiso ka ho fetohela ho Sic Crucibles.
Sic Crucibles ke sesebelisoa sa bohlokoa haholo bakeng sa liindasteri tse hlokang lisebelisoa tse sebetsang hantle tse khonang ho mamella mocheso o feteletseng le ho pepesetsoa lik'hemik'hale. Ka ho utloisisa thepa ea bona le ho latela liprothokholo tse nepahetseng tsa tlhokomelo, likhoebo li ka ntlafatsa ts'ebetso ea ts'ebetso ha li ntse li fokotsa nako.
