Ho na le phapang e khōlō pakeng tsali-crucibles tsa silicon carbidele li-crucible tsa graphite likarolong tse ngata tse kang thepa, mekhoa, ts'ebetso le litheko. Phapang ena ha e ame feela ts'ebetso ea eona ea tlhahiso, empa hape e khetholla katleho ea eona le maemo a ts'ebeliso.
phapang e kgolo
Li-crucibles tsa graphite li entsoe haholo-holo ka graphite ea tlhaho ea tlhaho 'me e sebelisa letsopa e le tlamahano. Motsoako ona o fana ka graphite crucible e babatsehang conductivity ea mocheso le mocheso o phahameng oa ho hanyetsa, ho etsa hore e tšoanelehe bakeng sa lits'ebetso tsa ho qhibiliha ha mocheso o phahameng. Sebopeho se ikhethang le conductivity e phahameng ea mocheso oa tlhaho ea flake graphite e etsa hore li-crucible tsa graphite li ratoe haholo indastering ea metallurgical le foundry.
Silicon carbide crucible e thehiloe holim'a graphite ea tlhaho ea flake, e nang le silicon carbide e le karolo ea mantlha le resin e phahameng ea mocheso joalo ka setlamo. Joalo ka thepa e thata haholo, silicon carbide e na le khanyetso e phahameng haholo ea ho roala le botsitso ba mocheso, e lumellang li-crucible tsa silicon carbide ho sebelisoa libakeng tse thata ho feta. Tšebeliso ea resin ea mocheso o phahameng e boetse e matlafatsa matla le ho tšoarella ha crucible.
Phapang ea ts'ebetso
Mokhoa oa ho etsa graphite crucible haholo-holo o itšetlehile ka ho hatisa ka letsoho le ka mochine. Li-crucibles tse nyane tsa graphite hangata li entsoe ka ho hatelloa ka mechini, ebe li chesoa ka sebōping ka mocheso o phahameng oa likhato tse 1,000, 'me qetellong li koahetsoe ka glaze e khahlanong le kutu kapa pente e thibelang mongobo ho eketsa nako e telele le ho hanyetsa ho bola. Ts'ebetso ena ea setso, le hoja e le litšenyehelo, e na le meeli mabapi le katleho ea tlhahiso le boleng bo tsitsitseng.
Ts'ebetso ea tlhahiso ea silicon carbide crucible e batla e tsoetse pele, e sebelisa lisebelisoa tsa khatiso tsa isostatic le foromo ea mahlale. Theknoloji ea ho hatella ea Isostatic e sebetsa khatello e tšoanang (ho fihla ho 150 MPa), e bakang sekhahla se phahameng le ho tsitsisa ha crucible. Ts'ebetso ena ha e ntlafatse matla a mochine oa crucible feela, empa hape e ntlafatsa haholo ho hanyetsa mocheso oa mocheso le ho bola.
Liphapano tsa ts'ebetso
Mabapi le ts'ebetso, ho na le phapang e kholo lipakeng tsa graphite crucibles le silicon carbide crucibles. Li-crucible tsa graphite li na le boima ba 13 kA/cm², ha li-crucible tsa silicon carbide li na le boima ba 1.7 ho isa ho 26 kA/mm². Bophelo ba ts'ebeletso ea li-graphite crucibles hangata ke makhetlo a 3-5 a silicon carbide crucibles, e leng haholo-holo ka lebaka la matla a phahameng a thepa le ho hanyetsa ho bola ha li-silicon carbide crucibles.
Ho phaella moo, phapang ea mocheso pakeng tsa ka hare le ka ntle ho graphite crucible e ka bang likhato tse 35, ha phapang ea mocheso oa silicon carbide crucible e le likhato tse 2-5 feela, e leng se etsang hore silicon carbide crucible e phahametse haholoanyane ho latela taolo ea mocheso le mocheso. botsitso. Acid le alkali resistance and corrosion resistance of silicon carbide crucibles le tsona li phahame haholo ho feta tsa graphite crucibles, tse ntlafatsang haholo ts'ebetso ea matla le ho boloka matla a ka bang 50% ho feta crucibles ea graphite.
phapang ka theko
Ka lebaka la ho se tšoane ha thepa le mekhoa ea tlhahiso, li-graphite crucibles le li-silicon carbide crucibles le tsona li na le phapang e khōlō ea theko. Ka tloaelo, li-crucible tsa silicon carbide li theko e boima ka makhetlo a mararo ho feta li-graphite crucibles. Phapang ena ea theko e bonts'a melemo ea bohlokoa ea silicon carbide crucibles mabapi le litšenyehelo tsa thepa, ho rarahana ha mokhoa oa tlhahiso le ts'ebetso.
Ka kakaretso, le hoja li-crucibles tsa silicon carbide li bitsa chelete e ngata, ho tšoarella ha tsona ho phahameng, ho hanyetsa kutu, le matla a matla a matla li etsa hore e be khetho e theko e tlaase bakeng sa lisebelisoa tse ngata tse boima. Li-crucible tsa graphite li lula li sebelisoa haholo lits'ebetsong tse ngata tsa setso ka lebaka la theko e tlase le thepa e ntle ea mantlha. Melemo le mefokolo e fapaneng ea li-crucible tsena tse peli li etsa qeto ea hore li loketse maemo a fapaneng a kopo.
