1. silicon carbide crucible ke eng?
Silicon carbide crucible ke sejana se nang le mocheso o phahameng se sebelisang silicon carbide (SiC) joalo ka thepa e tala ea mantlha. E sebelisoa haholo-holo bakeng sa ho qhibilihisa le ho sebetsana le litšepe tse fapa-fapaneng le li-alloys. Silicon carbide ke thepa ea maiketsetso e nang le boima bo phahameng haholo le ho hanyetsa mocheso. E sebelisoa haholo masimong a theknoloji e phahameng joalo ka ceramics, metallurgy, le semiconductors.
Hobane li-crucibles tsa silicon carbide li na le thepa e ntle ea 'mele le ea lik'hemik'hale tse kang mocheso o phahameng oa mocheso, coefficient e tlaase ea ho atolosa mocheso, le ho hanyetsa kutu, li bontša botsitso bo ke keng ba lekanngoa le ho tšoarella tlas'a mocheso o phahameng le maemo a feteletseng.
2. Melemo ea tekheniki ea silicon carbide crucible
1. Ho hanyetsa mocheso o phahameng haholo
Li-crucible tsa silicon carbide li na le mocheso o phahameng haholo 'me li khona ho mamella mocheso o fetang 1600 ° C. Sena se etsa hore e be tse loketseng bakeng sa ho qhibilihisa litšepe tse nang le mocheso o phahameng joalo ka koporo, aluminium le nickel. Ha ho bapisoa le li-crucibles tse entsoeng ka lisebelisoa tse ling, matla a silicon carbide crucibles ha a fokotsehe haholo tlas'a maemo a phahameng a mocheso, ho netefatsa hore sebopeho sa eona se tsitsitse nakong ea ts'ebetso ea ho qhibiliha.
Khanyetso ena e babatsehang ea mocheso o phahameng e thusa lik'hamphani ho qoba li-crucibles ho tloha ho senyeha kapa ho phunyeha ka lebaka la mocheso o phahameng, kahoo ho ntlafatsa tsoelo-pele ea tlhahiso le katleho.
2. Excellent mogote conductivity
Ntho e 'ngoe e hlokomelehang ea thepa ea silicon carbide ke mocheso oa eona o phahameng oa mocheso, o lumellang ho fetisoa ka potlako esita le mocheso. Sena se bolela hore nakong ea ts'ebetso ea ho qhibiliha, tšepe e qhibilihisitsoeng e ka fihla ka potlako mocheso o hlokahalang, ho fokotsa nako ea ho qhibiliha le ho ntlafatsa katleho ea tlhahiso.
Ts'ebetso ena e sebetsang ea mocheso e boetse e fokotsa mocheso o feteletseng oa tšepe e qhibilihisitsoeng, e thusang ho finyella taolo e nepahetseng haholoanyane ea mocheso nakong ea ts'ebetso ea ho lahla le ho netefatsa boleng bo tsitsitseng ba ho lahla.
3. Coefficient e tlase ea ho atolosa mocheso
Coefficient ea katoloso ea mocheso e bolela hore na thepa e atoloha hakae ha e futhumala. Silicon carbide e na le coefficient e tlase haholo ea katoloso ea mocheso, ho bolelang hore e fetoha e nyane haholo ka boholo ha e futhumala. Ka hona, esita le tikolohong e nang le liphetoho tse matla tsa mocheso, silicon carbide crucible e ka boloka sebōpeho sa eona sa pele 'me ea qoba mapetsong kapa tšenyo ka lebaka la ho atolosa kapa ho fokotseha.
Katoloso e tlase ea mocheso e loketse ka ho khetheha bakeng sa lits'ebetso tsa ho lahla tse kenyelletsang lipotoloho tsa ho futhumatsa khafetsa le ho pholisa, ho lelefatsa haholo bophelo ba ts'ebeletso ea crucible.
4. Excellent corrosion resistance
Nakong ea ts'ebetso ea ho qhibiliha, tšepe e qhibilihisitsoeng e itšoara ka crucible, butle-butle e senya bokaholimo ba eona. Leha ho le joalo, thepa ea silicon carbide e na le khanyetso e ntle ea lik'hemik'hale 'me e khona ho hanela khoholeho ea metsi a tšepe, haholo ha e sebetsana le litšepe tse sebetsang haholo tse kang koporo le aluminium.
Khanyetso e ntle ea kutu ha e atolose bophelo ba tšebeletso ea crucible feela, empa hape e fokotsa tšilafalo e bakoang ke ho senya holim'a metsi a crucible, ho netefatsa bohloeki ba mokelikeli oa tšepe le ho ntlafatsa boleng ba sehlahisoa sa ho qetela.
5. Matla a phahameng a mechine
Li-crucibles tsa silicon carbide li boloka matla a phahameng a mochine esita le mocheso o phahameng, ho etsa hore li se ke tsa senyeha kapa tsa senyeha. Tšobotsi ena e matla e phahameng e nolofalletsa crucible hore e mamelle tšusumetso ea tšepe e qhibilihisitsoeng le khatello ea mechine e ka ntle, ho boloka botsitso ba sebopeho nakong ea mocheso o phahameng oa mocheso.
6. Botsitso bo botle ba mocheso oa mocheso
Thermal shock stability e bolela bokhoni ba thepa ho hanela ho peperana ha mocheso o fetoha ka potlako. Li-crucibles tsa silicon carbide li bonts'a botsitso bo botle ba mocheso oa mocheso 'me li khona ho mamella liphetoho tse potlakileng tsa mocheso ntle le ho phatloha. Sena se bohlokoa haholo bakeng sa lits'ebetso tsa ho lahlela tse hlokang ho futhumatsa khafetsa le ho pholile.
tharo. Tšebeliso ea silicon carbide crucible
Ka lebaka la ts'ebetso ea eona e ikhethang ea ho hanyetsa mocheso o phahameng, conductivity ea mocheso, le ho hanyetsa kutu, li-crucible tsa silicon carbide li sebelisoa haholo mekhoeng e fapaneng ea ho qhibilihisa le ho lahla, haholo-holo ha ho qhibiliha litšepe tse se nang ferrous le li-alloys. Lintlha tse latelang ke tse 'maloa tse tloaelehileng tsa ts'ebeliso:
Copper casting: Ha o qhibilihisa koporo,silicon carbide crucibles e ka boloka junifomo ea mocheso oa ho qhibiliha, ea fokotsa ho thehoa ha litšila, le ho ntlafatsa boleng ba likarolo tsa koporo.
Aluminium le aluminium alloy smelting: Aluminium e sebetsana habonolo le crucible nakong ea ts'ebetso ea ho qhibiliha, empa ho hanyetsa ha silicon carbide ho sireletsa crucible hore e se ke ea bola le ho lelefatsa bophelo ba eona ba tšebeletso.
Tse ling tse nang le mocheso o phahameng oa mocheso: Silicon carbide crucible e boetse e loketse ho qhibilihisa litšepe tse nang le mocheso o phahameng joalo ka zinki le nickel, 'me e na le matla a ho ikamahanya le maemo.
Tse nne. Tšebeliso le tlhokomelo ea silicon carbide crucible
Ho eketsa bophelo ba ts'ebeletso ea silicon carbide crucibles, tšebeliso e nepahetseng le tlhokomelo e bohlokoa. Litlhahiso tse ling ke tsena:
Preheat crucible: Pele o sebelisoa kapa o sebelisoa hape, ho kgothaletswa hore butle-butle o futhumatsa crucible ho mocheso o sebetsang ho thibela ho futhumala ha tšohanyetso le ho phatloha.
Qoba ho futhumatsa le ho pholile ka potlako: Le hoja li-crucible tsa silicon carbide li na le botsitso bo botle ba mocheso oa mocheso, liphetoho tse potlakileng haholo tsa mocheso li ntse li ka senya crucible.
Ho hlahloba khafetsa: Nakong ea ts'ebeliso, kamehla hlahloba sebaka sa crucible bakeng sa matšoao a mapetsong kapa ho bola, 'me u rarolle mathata a ka bang teng ka nako.
