Isingeniso: I-graphite crucibles ingahlukaniswa cishe izigaba ezine.
1.I-graphite crucible ehlanzekile.Okuqukethwe kwekhabhoni kuvamise ukuba kukhulu kuno-99.9%, futhi kwenziwa ngezinto ezihlanzekile zokwenziwa zegraphite.Kunconywa kuphela ukusebenzisa ezinye izinhlobo zesithando somlilo ngokucophelela ezithandweni zikagesi.
2.Clay graphite crucible.Yenziwe ngempushana ye-graphite yemvelo exutshwe nobumba nezinye izinto ezimelana ne-oxidation ye-binder, futhi yakhiwe ngokuzungeza.Ilungele amafekthri anezindleko eziphansi zomsebenzi nezinga 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.Ifanele ukuncibilika kokuhlolwa kwezinga lokushisa eliphezulu, 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.Yiyona efaneleka kakhulu ku-aluminium ne-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 se-crucibles: isithando somlilo se-coke, isithando somlilo sikawoyela, isithando somlilo segesi yemvelo, isithando somlilo sokumelana, isithando somlilo esiphakathi nendawo (sicela uqaphele ukuthi ukuncibilika kahle kwe-aluminium akuphakeme), isithando somlilo sezinhlayiyana ze-biological, njll. Ifanele ukuncibilikisa ithusi, igolide, isiliva , i-zinc, i-aluminium, i-lead, i-cast iron nezinye izinsimbi ezingenayo insimbi.Kanye ne-asidi engaqinile namakhemikhali e-alkali aqinile anoketshezi oluphansi, ukumelana nokugqwala kanye nokumelana nokushisa okuphezulu.
Imiyalo yokusetshenziswa kwe-graphite crucible (sicela ufunde ngokucophelela ngaphambi kokusetshenziswa):
I-1.I-crucible igcinwa endaweni enomoya futhi eyomile ukuze igweme 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 ezingaphezulu neziphansi nezizungezile kufanele zihlangabezane nezidingo, futhi isembozo somlilo akufanele sicindezelwe emzimbeni ohlabayo.
5. Gwema umjovo oqondile welangabi emzimbeni obethelekayo ngesikhathi sokuwusebenzisa, futhi kufanele ufuthwe ubheke esisekelweni se-crucible.
6. Uma wengeza izinto, kufanele zengezwe kancane, okungcono okuchotshoziwe.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 usebenzise kangcono ukusebenza kwayo okuphezulu.
9. Ngesikhathi senqubo yokuncibilikisa, inani lokufakwayo le-ejenti kufanele lilawulwe.Ukusetshenziswa ngokweqile kuzonciphisa impilo yesevisi ye-crucible.
10. Uma usebenzisa i-crucible, zungeza i-crucible ngezikhathi ezithile ukuze wenze ukushisa ngokulinganayo futhi ukwandise ukusetshenziswa.
11. Thepha kancane lapho ususa i-slag ne-coke ezindongeni zangaphakathi nangaphandle ze-crucible ukuze ugweme ukulimala ku-crucible.
12. Ukusetshenziswa kwe-solvent ye-graphite crucible:
I-1) Ukunakwa kufanele kukhokhwe lapho wengeza i-solvent: i-solvent kufanele yengezwe ensimbi encibilikisiwe, futhi kwenqatshelwe ngokuphelele ukufaka i-solvent embizeni engenalutho noma ngaphambi kokuba insimbi incibilike: gubungula insimbi encibilikisiwe ngokushesha ngemva kokwengeza okuncibilikisiwe. insimbi.
2) Indlela yokujoyina:
a.Izinto ezincibilikayo ziyimpushana, inqwaba, nezingxube zensimbi.
b, igama lesicelo lenqwaba liyancibilika libe phakathi nendawo ye-crucible kanye nengxenye eyodwa kwezintathu yendawo ngenhla kwendawo engaphansi.
c.I-flux eyimpushana kufanele yengezwe ukuze igweme ukuthintana ngqo nodonga lwe-crucible.d.Kuvinjelwe ngokuqinile ukuthi i-flux ihlakazeke esithandweni esincibilikayo, ngaphandle kwalokho izogqwala udonga lwangaphandle lwe-crucible.
e, Inani elingeziwe liyinani elincane elishiwo umenzi.
f.Ngemuva kokuthi i-ejenti yokucwenga kanye ne-modifier yengezwe, insimbi encibilikisiwe kufanele isetshenziswe ngokushesha.
g, qinisekisa ukuthi kusetshenziswe i-flux efanele.Ukuguguleka kwe-Flux ku-graphite crucible Ukuguguleka kwesilungisi esicwengisiswayo: I-fluoride ekusilungiseni esicwengisisayo izoguguleka i-crucible kusukela engxenyeni engezansi (R) yodonga olungaphandle lwe-crucible.
Ukugqwala: I-slag enamathelayo e-crucible kufanele ihlanzwe nsuku zonke ekupheleni kweshifu.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.
