Isingeniso: I-graphite crucibles ingahlukaniswa cishe izigaba ezine.
1.I-graphite crucible ehlanzekile.Iokuqukethwe kwekhabhoningokuvamile inkulu kune99.9%, futhi yenziwe nge-graphite yokwenziwa emsulwa.Kunconywa kuphela ukusebenzisa ezinye izinhlobo zesithando somlilo ngokucophelelaizithando zikagesi.
2.Clay graphite crucible.Yenziwe ngempushana ye-graphite yemvelo exutshwe nobumba nezinye izinto ezimelana ne-oxidation ye-binder, futhi yakhiwe ngokuzungeza.Ilungele izimboni ezino-lizindleko zomsebenzifuthiizinga eliphansi lokusebenza.
I-3.I-silicon carbide graphite crucible, eyenziwe ngokujikelezayo.Yenziwe ngempushana ye-graphite yemvelo, i-silicon carbide, i-aluminium oxide, njll. ixutshwe njengezinto ezingavuthiwe, i-spin-molded, futhi yengezwe nge-anti-oxidation layer.Ukuphila kwenkonzo cishe izikhathi ezingu-3-8 kune-clay graphite crucible.Ukuminyana kwenqwaba kuphakathi kuka-1.78-1.9.Ifaneleizinga lokushisa eliphezulu lokuncibilikisa ukuncibilika, isidingo esidumile.
I-4.I-silicon carbide graphite crucible yenziwa ngokucindezela kwe-isostatic, futhi i-crucible icindezelwa umshini wokucindezela isostatic.Impilo yesevisi ngokuvamile iphindwe izikhathi ezingu-2-4 kune-rotary eyakhiwe nge-silicon carbide graphite crucible.Yilona elifaneleka kakhului-aluminiumfuthii-zinc oxide.Ezinye izinsimbi kufanele zikhethwe ngokucophelela, futhi ama-induction furnaces kufanele akhethwe ngokucophelela.Ngenxa yezindleko eziphezulu zokucindezela kwe-isostatic, ngokuvamile azikho iziphambano ezincane.

Izinhlobo zesithando somlilo zama-crucibles:isithando somlilo se-coke, isithando somlilo samafutha, isithando somlilo segesi yemvelo, isithando somlilo, isithando somlilo esiphakathi(sicela uqaphele ukuthi ukuncibilika kahle kwe-aluminium akuphakeme), isithando somlilo sezinhlayiyana zebhayoloji, njll. Ifanele ukuncibilikisa ithusi, igolide, isiliva, i-zinc, i-aluminium, i-lead, insimbi ekhonjiwe nezinye izinsimbi ezingenayo insimbi.Kanye ne-asidi engaqinile namakhemikhali e-alkali aqinileuketshezi oluphansi, ukumelana nokugqwalafuthiukumelana nokushisa okuphezulu.
Imiyalo yokusetshenziswa kwe-graphite crucible (sicela ufunde ngokucophelela ngaphambi kokusetshenziswa):
1.I-crucible igcinwa ku-akungene umoyafuthiomileimvelo ukugwema ukuthintwa umswakama.
2. I-crucible kufanele iphathwe ngokucophelela, ivinjelwe ngokuqinile ukuwisa nokuzamazama, futhi ungaguquki, ukuze ungalimazi ungqimba oluvikelayo ebusweni be-crucible.
3. Bhaka i-crucible kusengaphambili ngaphambi kokuyisebenzisa.Izinga lokushisa lokubhaka likhuphuka kancane kancane lisuka phansi liye phezulu, futhi i-crucible iphenduka njalo ukuze ivumele ukushisa ngokulinganayo, isuse umswakama ku-crucible, futhi kancane kancane ikhulise izinga lokushisa lokushisa libe ngaphezu kwama-500 (njengokushisa).Okungalungile, okubangela ukuthi i-crucible iqhume futhi iqhume, akuyona inkinga yekhwalithi futhi ngeke ibuyiswe)
4. Isithando somlilo se-crucible kufanele sihambisane ne-crucible, izikhala ezingenhla nezingezansi nezizungezile kufanele zihlangabezane nezidingo, futhiikhava yesithando somlilo akufanele icindezelwe emzimbeni we-crucible.
5. Gwema umjovo welangabi oqondile emzimbeni we-crucible ngesikhathi sokusebenzisa, futhi kufanele kubeifuthwe ngasesisekelo se-crucible.
6. Lapho wengeza izinto, kufanele zengezwe kancane, okungconoimpahla echotshoziwe.Ungapakishi kakhulu noma uminyene kakhulu ezintweni ze-aniseed, ukuze ungaqhumi i-crucible.
7. Ama-crucible tongs asetshenziselwa ukulayisha nokulayisha kufanele ahambisane nokuma kwe-crucible, ukuze angalimazi i-crucible.
8. Kungcono ukusebenzisa i-crucible ngokuqhubekayo, ukuze isebenzise kangcono ukusebenza kwayo okuphezulu.
9. Phakathi nenqubo yokuncibilikisa, inani lokufaka lei-ejenti kumele ilawulwe.Ukusetshenziswa ngokweqile kuzonciphisa impilo yesevisi ye-crucible.
10. Uma usebenzisa i-crucible,zungezisa i-crucible ngezikhathi ezithileukwenza ukushisa ngokulinganayo futhi andise ukusetshenziswa.
11.Thepha kancanelapho ususa i-slag ne-coke ezindongeni zangaphakathi nangaphandle ze-crucible ukugwema ukulimala ku-crucible.
12. Ukusetshenziswa kwe-solvent ye-graphite crucible:
I-1) Ukunaka kufanele kukhokhwe lapho wengeza i-solvent:i-solvent kufanele yengezwe ensimbi encibilikisiwe, futhi kwenqatshelwe ngokuphelele ukwengeza i-solvent embizeni engenalutho noma ngaphambi kokuba insimbi incibilike: gubha insimbi encibilikisiwe ngokushesha ngemva kokwengeza insimbi encibilikisiwe.
2) Indlela yokujoyina:
a.Izinto ezincibilikayo ziyimpushana, inqwaba, nezingxube zensimbi.
b, igama lesicelo lenqwaba liyancibilikaphakathi nendawo ye-cruciblefuthiingxenye eyodwa kwezintathu yesikhundla ngaphezu kwendawo engaphansi.
c.I-flux powder kufanele yengezwe kuyogwema ukuthintana ngqo nodonga lwe-crucible.d.Ikonakwenqatshelwe ngokuqinile ukuthi ukugeleza kuhlakazeke esithandweni esincibilikayo, kungenjalouzogqwala udonga lwangaphandlewe-crucible.
e, Inani elingeziwe yi-inani elincaneecaciswe umenzi.
f.Ngemuva kokuthi i-ejenti yokucwenga kanye ne-modifier yengezwe, insimbi encibilikisiwekufanele isetshenziswe ngokushesha.
g, qinisekisa ukuthi kusetshenziswa i-flux efanele.Ukuguguleka kwe-Flux ku-graphite crucible Ukuguguleka kwesilungisi esicwengwayo: I-fluoride ekusilungiseni esicwengisisayo izoguguleka i-crucible kusukela engxenyeni engezansi (R) yodonga olungaphandle lwe-crucible.
Ukugqwala: I-slag enamathelayo e-crucible kufanele ibekuhlanzwa nsuku zonkeekupheleni koshintsho.Ukuwohloka okungaphenduliwe kuzocwiliswa ku-slag futhi kusakazeke ku-crucible, okwandisa ingozi yokucwenga ukuwohloka nokuguguleka.Izinga lokushisa nokugqwala: Izinga lokusabela le-crucible kanye ne-ejenti yokucwenga lilingana nezinga lokushisa.Ukwandisa izinga lokushisa eliphezulu ngokungadingekile kwe-alloy liquid kuzonciphisa kakhulu impilo ye-crucible.Ukugqwala komlotha we-aluminium kanye ne-aluminium slag: Ngomlotha we-aluminium oqukethe usawoti ojulile we-sodium nosawoti we-phosphorus, isimo sokugqwala siyafana nalesi esingenhla, esizofinyeza kakhulu impilo ye-crucible.Ukuguguleka kwesilungisi esinoketshezi oluhle: Uma isilungisi esinoketshezi oluhle lwengezwa, insimbi encibilikisiwe kufanele inyakaziswe ngokushesha ukuze ingakwazi ukuthintana nomzimba webhodwe.
13. Ithuluzi Lokuhlanza I-Graphite Crucible Slag Cleaning: Ithuluzi liyindilinga nge-curvature efana nodonga lwangaphakathi lwebhodwe elisetshenzisiwe.Ukususwa kokuqala: Ngemva kokushisa nokusetshenziswa kokuqala, ukususwa kwe-slag ekhiqizwayo kubaluleke kakhulu.I-slag ekhiqizwa okokuqala ithambile impela, kepha ngemuva kokushiywa iba nzima kakhulu futhi kube nzima ukuyisusa.Isikhathi Sokuhlanza:Ngenkathi i-crucible isashisa futhi i-slag ithambile, kufanele ihlanzwe nsuku zonke.
