Ukusebenza Okuphezulu Kwezinga Lokushisa Kwezikhonkwane Ze-Silicon Carbide

I-silicon carbide crucibleszaziwa ngokusebenza kwazo okuhle kakhulu kwezinga lokushisa eliphezulu futhi ziyakwazi ukumelana namazinga okushisa aphakeme kakhulu okusebenza. Ngokuvamile, izinsimbi ze-silicon carbide crucibles zekhwalithi ephezulu zingasebenza ngokuphepha nangokuzinza ebangeni lokushisa elingu-1600°C kuya ku-2200°C (2912°F kuya ku-3992°F), kanti ezinye iziphamba eziklanywe ngokukhethekile zaphathwa futhi zingakwazi ukumelana nezinga lokushisa elifinyelela ku-2700°. C (4952°F).

Ezisetshenziswa ezingokoqobo ekuhlolweni kwezinga lokushisa eliphezulu noma izinqubo zokukhiqiza ezifana nokuncibilikiswa kwensimbi nokucwiliswa kwe-ceramic, izinga lokushisa elithile lokusebenza le-silicon carbide crucible lidinga ukunqunywa ngokusekelwe ezidingweni ezithile zenqubo, izimo zomkhathi kanye nezakhiwo zamakhemikhali zezinto ezibonakalayo. Ukwengeza, izinqubo zokusebenza ezifanele kufanele zilandelwe ukuze kuvinjwe i-crucible ukuthi ingaqhekeki noma yonakaliswe ngenxa yezinguquko ezisheshayo ekushiseni.

Nakuba i-silicon carbide crucibles ingakwazi ukumelana namazinga okushisa aphezulu, kubalulekile ukugwema ukudlula izinga lokushisa eliphezulu lokusebenza ukuvimbela ukulimala kwempahla noma ukubonakala kokungcola. Izinqubo zokupholisa ezifanele kufanele zilandelwe ngemva kokusetshenziswa ukuvimbela ukuqhekeka lapho kubekwa ezindaweni ezibandayo, futhi ukunakekelwa kufanele kuthathwe ukuze kugwenywe umthelela omkhulu womzimba ngesikhathi sokusetshenziswa ukuze kuvinjelwe umonakalo.
