Embonini yesimanje kanye nocwaningo lwesayensi, ama-crucibles adlala indima ebalulekile ekuncibilikiseni izinsimbi, ukuhlolwa kwamakhemikhali, nezinye izinhlelo zokusebenza eziningi. Nokho,I-Crucible Yokuncibilikabavame ukuhlangabezana nezinkinga ezihlukahlukene ngesikhathi sokusetshenziswa, njengokuqhekeka okuphambene, ukuqhekeka kwe-longitudinal, nokuqhekeka okumise okwenkanyezi. Lesi sihloko sizokwethula izinkinga ezivamile ngalezi ziphambano futhi sihlaziye izimbangela ezingaba khona ukusiza ukuxazulula lezi zinkinga.
Inkinga yokuqhekeka okuguquguqukayo
Imifantu engemuva eduze naphansi kwe-melting crucible: Lolu hlobo lokuqhekeka ngokuvamile lwenzeka eduze naphansiI-Casting Cruciblefuthi kungase kubangele ukuwa kwe-crucible. Izizathu ezingaba khona zihlanganisa:
- Phakathi nenqubo yokushisa, izinga lokushisa likhuphuka ngokushesha kakhulu.
- Sebenzisa into eqinile (njengensimbi) ukuze ushaye phansi.
- Insimbi esele ngaphansi kwe-crucible ithola ukunwetshwa kokushisa.
- Izinto eziqinile zithinta ingaphakathi le-crucible, njengokujikijela okokuphonsa ku-crucible.
Ukuqhekeka okuphambene okutholakala cishe maphakathi ne-Metal Casting Crucible:Lokhu kuqhekeka kungase kuvele phakathi kwe-Frnace Crucible, futhi izizathu zingabandakanya:
- Beka i-crucible kusisekelo esingafanele.
- Sebenzisa izidladla ze-Smelting Crucibles ukuze ubambe indawo ephakeme kakhulu futhi usebenzise amandla amakhulu.
- Ukulawulwa okungalungile kwesishisi kubangele ukushisa ngokweqile kwe-crucible nokungasebenzi kahle kwezinye izingxenye, okuholela ekucindezelekeni kokushisa.
Uma usebenzisa i-tilting (ngenozzle)I-Clay Graphite Crucibles, kungase kube nemifantu ephambanayo engxenyeni engezansi yombhobho obhobozayo.Lokhu kuqhekeka kungase kubangelwe ukufakwa okungalungile kwe-crucible, futhi inhlabathi ephikisayo ingase ifakwe ngaphansi kwe-nozzle crucible lapho ufaka i-crucible entsha.
Inkinga yokuqhekeka kwe-longitudinal
I-crucible esetshenziswe okokuqala inemifantu ye-longitudinal ehamba ngaphansi kwe-Sic Crucibles emaphethelweni aphansi: lokhu kungase kubangelwe ukubeka i-crucible epholile emlilweni wezinga lokushisa eliphezulu noma ukushisa okuphansi ngokushesha okukhulu ngenkathi i-crucible ipholile. Ukucindezeleka okushisayo kubangela ukuqhekeka phansi kwe-crucible, ngokuvamile ehambisana nezimo ezifana nokucwenga kwe-glaze.
Ngemuva kokusetshenziswa isikhathi eside kwe-crucible, imifantu ye-longitudinal ivela odongeni, futhi udonga oluyi-crucible endaweni yokuqhekeka luncane:lokhu kungase kube ngenxa yokusondela kwe-crucible noma ukufinyelela impilo yayo yesevisi, futhi udonga lwe-crucible luba luncane, lungakwazi ukumelana nokucindezela okukhulu.
Ukuqhekeka kwe-longitudinal okukodwa okusuka phezulu konqenqema lwe-crucible: Lokhu kungase kube ngenxa yokushisa okudlulele kwe-crucible, ikakhulukazi uma isivinini sokushisa emaphethelweni angezansi nangaphansi kwe-crucible sishesha kunaleyo ephezulu. Kungase futhi kubangelwe amapulangwe e-crucible angafanelekile noma umthelela wokuphakela ingot onqenqemeni olungaphezulu.
Imifantu ye-longitudinal ehambisanayo esuka onqenqemeni olungaphezulu lweziphambano eziningi:Lokhu kungase kube ngenxa yesembozo sesithando somlilo esicindezela ngokuqondile ku-crucible, noma igebe phakathi kwesembozo sesithando somlilo kanye ne-crucible ibe nkulu kakhulu, okwenza i-crucible ithambekele ku-oxidation futhi iholele ekuqhekekeni.
Imifantu ye-longitudinal ohlangothini lwe-crucible:ngokuvamile okubangelwa ukucindezela kwangaphakathi, njengokubeka okusansimbi okupholile okumise okwe-wedge ngokuvundlile ku-crucible, okungabangela umonakalo onjalo lapho kushisa futhi kunwetshwa.
Xhumana nathi ukuze sikunikeze ifomu lokuhlaziya ukwehluleka okunemininingwane eminingi
Izinkinga ezivamile nokuhlaziywa kwalezi zinsimbi zisekelwe emashumini eminyaka ocwaningo kanye nesipiliyoni sokukhiqiza, ngethemba lokusiza amakhasimende ukuthi aqonde kangcono izinkinga ezingase zihlangabezane nazo ekusetshenzisweni kwama-crucibles futhi athathe izinyathelo ezifanele zokuxazulula lezi zinkinga. Ngesikhathi sokukhiqiza kanye nokusetshenziswa kwezinsimbi, ikhwalithi kanye nesevisi yangemuva kokuthengisa ibalulekile ukuze kuqinisekiswe izintshisekelo nokwethenjwa kwamakhasimende.
