Ukuthuthukisa ukuphepha kwezimboni kanye nokusebenza kahle ngokusetshenziswa okufanele kwama-graphite ama-braphite

Eminyakeni yamuva, ukusetshenziswa kweama-graphite ama-brucIblesEkubhemeni kwensimbi yezimboni kanye nokusakaza bekulokhu kukhula ngokuqinile, ngenxa yedizayini yabo esekwe ku-ceramic enikeza amandla aphezulu okumelana. Kodwa-ke, ekusetshenzisweni okungokoqobo, abaningi bebheka inqubo ebaluleke kakhulu yokushisa okuthe xaxa kwama-graphite ama-graphite, okuholela ezingcupheni ezingaba khona ekuphepheni komuntu siqu nokwesakhiwo ngenxa yokuqhekeka okubaleka. Ukwandisa izinzuzo ze-graphite amabhulukwe, sinikeza izincomo ezenzelwe ngokwesayensi ngokusetshenziswa kwazo, ukuqinisekisa ukukhiqizwa okusebenzayo kanye nokuphepha kwezimboni.

Izici ze-Graphite Crucibles

Ama-graphite ama-brucibles adlala indima ebalulekile ekunciphiseni kwensimbi nokusakazeka ngenxa yokuvuka kwabo okuvelele okuvelele. Ngenkathi bebonisa okungcono kakhulu okushisayo okushisayo kuqhathaniswa nama-silicon carbide ama-rucibles, athambekele ku-oxidation futhi abe nezinga eliphakeme lokuphuka. Ukubhekana nalezi zingqinamba, kubalulekile ukuqasha inqubo yesayensi ezwakalayo yesayensi.

Imihlahlandlela Yokugcina

1. Ukubekwa eduze kwesithando somlilo sokuhlasela: Beka i-Earchecible eduze kwesithako samafutha amahora angama-4-5 ngaphambi kokusetshenziswa kokuqala. Le nqubo yokuhlola inzalo ekwakhiweni komhlaba, ukuthuthukisa ukuqina kwecala.
2. Ukushiswa kwamalahle noma ngokhuni: Beka amalahle noma izinkuni ngaphakathi kokubethelwa futhi ushise cishe amahora amane. Lesi sinyathelo sisiza ekuqubeni kokuqunjelwa futhi sithuthukise ukumelana nokushisa okubaleka.
3. Ukushisa okushisa umkasha
   • 0 ° C kuya ku-200 ° C: Ukushisa kancane amahora ama-4 (isithando samafutha) / Electric
   • 0 ° C kuya ku-300 ° C: Ukushisa kancane kwehora eli-1 (ugesi)
   • 200 ° C kuya ku-300 ° C: Ukushisa kancane amahora amane (isithando somlilo)
   • I-300 ° C kuya ku-800 ° C: Ukushisa kancane amahora ama-4 (isithando somlilo)
   • I-300 ° C kuya ku-400 ° C: Ukushisa kancane amahora ama-4
   • I-400 ° C kuya ku-600 ° C: Ukushisa okusheshayo, ukulondolozela amahora ama-2
4. Ukuvuselela kabusha kwe-Supdown: Ngemuva kokuvalwa phansi, isikhathi sokuvuselela uwoyela namafutha kagesi ngokulandelayo:
   • 0 ° C kuya ku-300 ° C: Ukushisa kancane kwehora eli-1
   • I-300 ° C kuya ku-600 ° C: Ukushisa kancane amahora ama-4
   • Ngaphezulu kwe-600 ° C: Ukushisa okusheshayo kuya ekushiseni okudingekayo

Imihlahlandlela yokuvala

• Okwezithakazi zikagesi, kungakuhle ukuthi ulondoloze ukuguquguquka okuqhubekayo lapho ungenzi lutho, ngokushisa kusethwa cishe ngo-600 ° C ukuvikela ukupholisa okusheshayo. Uma ukufakwa kungabi khona, khipha izinto zokwenziwa kusuka entweni enokwethenjelwa ukunciphisa okuqukethwe okusele.
• Kumathele kawoyela, ngemuva kokuvalwa, qiniseka ukuthi uthwebula izinto zokwakha ngangokunokwenzeka. Vala izimbotshana zezimboni zomlilo kanye nomoya omncane ukuze ulondoloze ukushisa okusele futhi uvikele umswakama onokuqonda.

Ngokunamathela kulezi zinkombandlela zesayensi ezisekelwe ngokwesayensi kanye nokuphepha okuvikelekile, ukusebenza kahle kwe-graphite ama-brappite ekukhiqizeni kwezimboni kungaqinisekiswa, kanyekanye nokwenza ngcono ukuphepha kwezimboni kanye nokuvikela ukuphepha kwezimboni. Masibe ndawonye ngokuhlanganyela ekuqashelweni kwezobuchwepheshe ukushayela inqubekela phambili yezimboni.
