Lefatšeng la mahlale a metallurgy le thepa,crucibleke sesebelisoa sa bohlokoa bakeng sa ho qhibiliha le ho akhela litšepe.Har'a mefuta e sa tšoaneng ea li-crucibles, li-crucible tsa graphite silicon carbide (SiC) li hlahella ka thepa ea tsona e ikhethang, e kang mocheso o phahameng oa mocheso, ho hanyetsa mocheso o matla haholo, le botsitso bo phahameng ba lik'hemik'hale.Sehloohong sena, re tla hlahlobisisa risepe ea li-crucible tsa graphite SiC mme re hlahlobe hore na sebopeho sa bona se kenya letsoho joang ts'ebetsong ea bona e makatsang lits'ebetsong tse phahameng tsa mocheso.
Metsoako ea Motheo
Likarolo tse ka sehloohong tsa li-crucible tsa graphite SiC ke flake graphite le silicon carbide.Flake graphite, hangata e etsang 40% -50% ea crucible, e fana ka conductivity e ntle ea mocheso le lubricity, e thusang ho lokolloa ha tšepe ea tšepe habonolo.Silicon carbide, e etsang 20% -50% ea crucible, e ikarabella bakeng sa ho hanyetsa mocheso o phahameng oa mocheso oa crucible le botsitso ba lik'hemik'hale ka mocheso o phahameng.
Likarolo tse Eketsehileng Bakeng sa Ts'ebetso e Ntlafetseng
Ho ntlafatsa ts'ebetso e phahameng ea mocheso le botsitso ba lik'hemik'hale tsa crucible, likarolo tse ling li eketsoa ho risepe:
- Elemental silicon powder (4% -10%): E matlafatsa matla a mocheso o phahameng le khanyetso ea oxidation ea crucible.
- Boron carbide powder (1% -5%): E eketsa botsitso ba lik'hemik'hale le ho hanyetsa litšepe tse senyang.
- Clay (5% -15%): E sebetsa e le setlamo mme e ntlafatsa matla a mochine le botsitso ba mocheso oa crucible.
- Thermosetting binder (5% -10%): E thusa ho kopanya likarolo tsohle ho etsa sebopeho se momahaneng.
Foromo ea Boemo bo Phahameng
Bakeng sa lits'ebetso tse hlokang ts'ebetso e phahameng le ho feta, ho sebelisoa foromo e phahameng ea graphite crucible.Foromo ena e na le likaroloana tsa 98% tsa graphite, 2% calcium oxide, 1% zirconium oxide, 1% boric acid, 1% sodium silicate, le 1% aluminium silicate.Lisebelisoa tsena tse eketsehileng li fana ka khanyetso e ke keng ea lekanngoa ho mocheso o phahameng le tikoloho ea lik'hemik'hale tse mabifi.
Mokhoa oa Tlhahiso
Ho lokisoa ha li-crucible tsa graphite SiC ho kenyelletsa ts'ebetso e hlokolosi.Qalong, flake graphite le silicon carbide li kopantsoe hantle.Ebe, elemental silicon powder, boron carbide powder, letsopa, le thermosetting binder li kenngoa motsoako.Motsoako o ntan'o hatelloa hore o be sebōpeho ho sebelisoa mochine o batang oa khatiso.Qetellong, li-crucibles tse bōpehileng li kenngoa ka sebōping sa mocheso o phahameng ho matlafatsa matla a tsona a mochine le botsitso ba mocheso.
Lisebelisoa le Melemo
Li-crucible tsa Graphite SiC li sebelisoa haholo indastering ea metallurgic bakeng sa ho qhibiliha le ho lahla litšepe tse kang tšepe, tšepe, koporo le aluminium.Ts'ebetso ea bona e phahameng ea mocheso e tiisa ho futhumala ho tšoanang le ho fokotsa tšebeliso ea matla.Ho hanyetsa mocheso o phahameng oa mocheso ho fokotsa kotsi ea ho senya nakong ea liphetoho tse potlakileng tsa mocheso, ha botsitso ba lik'hemik'hale ba bona bo tiisa bohloeki ba tšepe e qhibilihisitsoeng.
Qetellong, risepe ea li-graphite silicon carbide crucibles ke motsoako o hlophisitsoeng hantle oa lisebelisoa tse fanang ka tekanyo ea conductivity ea mocheso, ho hanyetsa mocheso oa mocheso le botsitso ba lik'hemik'hale.Sebopeho sena se etsa hore e be tsa bohlokoa haholo lefapheng la metallurgy, moo li bapalang karolo ea bohlokoa ho qhibiliheng le ho lahla ha tšepe ka mokhoa o nepahetseng le o tšepahalang.
Ka ho utloisisa likarolo le ts'ebetso ea tlhahiso ea li-crucible tsa graphite SiC, liindasteri li ka etsa khetho e nepahetseng bakeng sa likopo tsa tsona tse khethehileng, ho netefatsa ts'ebetso e nepahetseng le nako e telele ea li-crucible tsa bona.Ha thekenoloji e ntse e tsoela pele, ho lebeletsoe hore ho be le lintlafatso tse ling ho risepe le mekhoa ea tlhahiso ea li-crucible tsa graphite SiC, tse bulang tsela bakeng sa lits'ebetso tse sebetsang hantle le tse tšoarellang tsa metallurgic.
