Ukuthuthukisa Ukuphepha Kwezimboni Nokusebenza Kahle Ngokusetshenziswa Okufanelekile Kwezinsimbi Ze-graphite

Eminyakeni yamuva, ukusetshenziswa kweama-graphite cruciblesezimbonini zokuncibilikisa nokubunjwa kwensimbi bekulokhu kukhula kancane kancane, ngenxa yedizayini yazo esekwe ngeceramic enikeza ukumelana nezinga lokushisa okuphezulu okukhethekile. Kodwa-ke, ekusetshenzisweni okungokoqobo, abaningi abayinaki inqubo ebalulekile yokushisisa kwangaphambili kwezinsimbi ezintsha ze-graphite, okuholela ezingozini ezingaba khona ekuphepheni komuntu siqu nempahla ngenxa yokuqhekeka okulimazayo. Ukwandisa izinzuzo ze-graphite crucibles, sinikeza izincomo ezisekelwe ngokwesayensi zokusetshenziswa kwazo okufanele, ukuqinisekisa kokubili ukukhiqiza okuphumelelayo nokuphepha kwezimboni.

Izici ze-Graphite Crucibles

Ama-graphite crucibles adlala indima ebalulekile ekuncibilikeni kwensimbi nasekuphontshweni ngenxa ye-thermal conductivity evelele. Ngenkathi zikhombisa ukuguquguquka okungcono kwe-thermal uma kuqhathaniswa ne-silicon carbide crucibles, zingenwa kalula yi-oxidation futhi zinezinga eliphezulu lokuphuka. Ukuze kuxazululwe lezi zinkinga, kubalulekile ukusebenzisa inqubo yokushisa ezwakala ngokwesayensi.

Imihlahlandlela Yokushisa Ngaphambili

1. Ukubekwa eduze kweSithando Somlilo Sokushisa Ngaphambi Kokushisa: Beka i-crucible eduze kwesithando somlilo samafutha amahora angu-4-5 ngaphambi kokusetshenziswa kokuqala. Le nqubo yokushisa ngaphambili isiza ekususeni umswakama ongaphezulu, okuthuthukisa ukuzinza kwe-crucible.
2. Ukushiswa Kwamalahle noma Izinkuni: Faka amalahle noma izinkuni ngaphakathi kwesitsha esishisayo bese ushisa cishe amahora amane. Lesi sinyathelo sisiza ekususeni umswakama futhi sithuthukise ukumelana nokushisa kwe-crucible.
3. I-Ramp-up Yezinga Lokushisa Esithandweni: Phakathi nesigaba sokuqala sokushisisa, kancane kancane wandise izinga lokushisa esithandweni ngokusekelwe ezigabeni zokushisa ezilandelayo ukuze uqinisekise ukuzinza nokuphila isikhathi eside kwe-crucible:
   • 0°C kuya ku-200°C: Ukushisisa kancane amahora angu-4 (isithando somlilo) / ugesi
   • 0°C kuya ku-300°C: Ukushisisa kancane ihora elingu-1 (ugesi)
   • 200°C kuya ku-300°C: Ukushisisa kancane amahora ama-4 (isithando somlilo)
   • 300°C kuya ku-800°C: Ukushisisa kancane amahora ama-4 (isithando somlilo)
   • 300°C kuya ku-400°C: Ukushisa kancane amahora ama-4
   • 400°C kuya ku-600°C: Ukushisa okusheshayo, kugcinwa amahora ama-2
4. Ukushisisa Kabusha Kokuthunyelwe: Ngemva kokuvala, isikhathi sokushisisa kabusha kwamafutha kanye nezithando zikagesi simi kanje:
   • 0°C kuya ku-300°C: Ukushisisa kancane ihora elingu-1
   • 300°C kuya ku-600°C: Ukushisisa kancane amahora ama-4
   • Ngaphezu kuka-600°C: Ukushisa okusheshayo kuya ezingeni lokushisa elidingekayo

Imihlahlandlela yokuvala shaqa

• Ezithandweni zikagesi, kuyatuseka ukuthi kugcinwe ukugqumisa okuqhubekayo uma kungenzi lutho, izinga lokushisa libekwe cishe ku-600 ° C ukuvimbela ukupholisa ngokushesha. Uma ukwahlukanisa kungenzeki, khipha izinto ku-crucible ukuze unciphise okuqukethwe okusele.
• Ezithandweni zikawoyela, ngemuva kokuvalwa, qinisekisa ukuthi ukhipha izinto zokwakha ngangokunokwenzeka. Vala isivalo somlilo nezimbobo zokungenisa umoya ukuze ulondoloze ukushisa okusalayo futhi uvimbele umswakama oshisayo.

Ngokunamathela kule mihlahlandlela yokushisa esekelwe ngokwesayensi kanye nezinyathelo zokuphepha zokuvala shaqa, ukusebenza kahle kwama-graphite crucibles ekukhiqizweni kwezimboni kungaqinisekiswa, ngasikhathi sinye kukhuliswe ukusebenza kahle kokukhiqiza nokuvikela ukuphepha kwezimboni. Masizibophezele ngokuhlangene ekusungulweni kwezobuchwepheshe ukuze siqhubekisele phambili inqubekelaphambili yezimboni.
