Ecubungula ukuncibilika kwe-aluminium - Thuthukisa kanye nokubuyisa kabusha ngempilo yenkonzo ende

1. Thuthukisa impahla ebelekile

Ukuqina kwezinhlobo ezahlukene ze-Earcidible kwimvelo ye-aluminium smelting iyahlukahluka. -JwayelekileEcubungula ukuncibilika kwe-aluminiumIzinto zokwakha zifaka:

I-Silicon Carbide Graphite-cashile (Sic-graphite): Ukushisa okushisa okusheshayo, ukumelana okushisa okuphezulu, ukumelana okuqinile okushisayo okushisayo, okulungele ukunyibilika kwe-aluminium, kunganciphisa ngempumeleloI-Aluminium ancibilika empiniukuqhekeka.

Ubumba-i-graphite-cashile (Clay-graphite):Ilungele ukuncibilika okuphansi kokushisa, inani lentengo liphansi, kepha ukumelana nokugqwala akukuhle njenge-silicon carbide-cashile.

Isincomo: IngomaneI-Aluminium ancibilika empini,I-Silicon Carbide Graphite-cashile uyisinqumo esihle kunazo zonke, ukumelana kwalo oxidation kunamandla, futhi impilo imayelana ne-30% -50% isikhathi eside kunobumba lwendabuko yendabuko-cashile, ukunciphisa imvamisa yokubuyiselwa kwemali kanye nezindleko zokonga. I-aluminium ebiyekile esikunikeza ine-17% ephakeme yokuvuselelwa okuphezulu okungu-17% kanye ne-20% yempilo ende yenkonzo kunaleI-Aluminium ancibilika empinikukhiqizwa ngabakhiqizi abafanayo

 

2. Ukuthuthukisa izinto zokufakwa kwe-thermal

Impahla yokufakwa okushisayo ngaphandle kweEcubungula nge-aluminiumIngxenye esemqoka ukuqinisekisa ukusetshenziswa kahle kwamandla okushisa futhi kunciphise ukulahleka kokushisa. Ukukhetha izinto ezifanele zokufakelwa kungakwazi ukuthuthukisa ukusebenza kahle kwe-Thermal kuphela, kepha futhi kunciphise ukusetshenziswa kwamandla futhi kunwebe impilo ye-Expament. Izinto ezijwayelekile zokufakelwa yilezi:

Isincomo:Khetha izinto ezifanele ngokusho kokushisa kokuncibilika. Ukwehlisa ukuqina okushisayo, okungcono ukusebenza kwe-thermal insulation. Cabanga nangemvamisa yokushisa njalo nokupholisa. Futhi kudingeka ucabangele ukumelana nokugqwala, ukumelana oxidation, ukunweba impilo yensiza. Into ebaluleke kakhulu ukubheka izindleko ezibonakalayo kanye nomphumela wokonga amandla.

 

3. Thuthukisa imodi yokushisa

Ukufudumeza

Izici: Ngokomthetho wokungeniswa kwe-electromagnetic, ama-Eddy currents akhiqizwa ngaphakathi kwensimbi ukushisaEcubungula nge-aluminiumuqobo. Ijubane lokushisa ngokushesha kanye nokusebenza kahle okushisayo. Ukulawulwa kokushisa okuqondile kwezidingo eziphezulu zokunemba.

Izinzuzo: Ukushisa okufanayo, ukunciphisa ukushisa ngokweqile kwasendaweni, ukwelula impilo yeI-Aluminium ancibilika empini. Akukho ukuxhumana ngqo nomthombo wokushisa okudingekayo ukunciphisa ukucindezela okushisayo ku-I-Aluminium ancibilika empiniingaphezulu. Ayikho inqubo yokuhlanganisa, ukunciphisa i-oxidation kanye nengozi yokugqwala.

Ukumelana nokushisa

Izici: Ngokusebenzisa okukhona ngokusebenzisa ucingo lokumelana ukuze ukhiqize ukushisa, ukufudumeza ngokungaqondileI-Aluminium ancibilika empini. Ijubane lokushisa kancane lingaholela kuI-Aluminium iphonsa ehlakaniphileUkuba sesimweni sokushisa esiphakeme isikhathi eside, kwandisa ukucindezelwa okushisayo. Ukusetshenziswa kwamandla okuphezulu, ukusetshenziswa kwesikhathi eside kungakhuphula izindleko zokusebenza.

Ukushisa igesi

Izici: Ngokushisa igesi yemvelo, igesi evuthayo namanye amafutha ukukhiqiza ilangabi lokushisa eliphakeme, ukufudumeza ngokuqondileI-Aluminium iphonsa ehlakaniphile. Ijubane lokushisa lishesha futhi izindleko zemishini ziphansi. Kodwa-ke, ukuxhumana ngqo kwelangabi ngeI-Aluminium ancibilika empinikungahle kuholele ekushiseni ngokweqile kwasendaweni futhi kwandise ukucindezela okushisayo. Igesi yokuphelelwa amandla ekhiqizwa ngesikhathi sokuvutha izosheshisa i-oxidation kanye nokugqwala kweI-Aluminium ancibilika empini.

Ukushisa uwoyela

Izici: Ngokushisa udizili, uwoyela osindayo namanye amafutha ukukhiqiza ilangabi eliphakeme lokushisa, ukufudumeza ngokuqondileI-Aluminium iphonsa ehlakaniphile. Ijubane lokushisa lishesha futhi izindleko zemishini ziphansi. Ukuxhumana okuqondile komlilo neI-Aluminium iphonsa ehlakaniphilekungadala ukushisa ngokweqile futhi kwandise ukucindezelwa okushisayo. Igesi yokuphelelwa amandla ekhiqizwa ngesikhathi sokuvutha izosheshisa i-oxidation kanye nokugqwala kweI-Aluminium iphonsa ehlakaniphile.

Isincomo:Ukuqhathanisa okuphelele kwezindlela zokushisa ngenhla, ukufudumeza kokufudumeza kungobungane kakhulu kuEcubungula ukuncibilika kwe-aluminium, izizathu eziphambili zimi ngalendlela elandelayo:

Endaweni yesicelo se-aluminium die casting, impilo yenkonzo yeAma-graphite ama-brucIbles we-aluminiumesithandweni segesi cishe izinyanga eziyi-10, nempilo yenkonzo yeAma-rucibles wokuncibilika kwe-aluminiumEsithandweni sokungeniswa yiminyaka emithathu-4. Lokhu kuqhathaniswa kwesikhathi kungakhombisa ngokugcwele izinzuzo zobuchwepheshe bokufudumeza kwe-induction ngempilo yenkonzo yeI-Ecucible for Aluminium Casting.

 

4. Thuthukisa uhlelo lokulawula lokushisa

Isincomo:: Hlanganisa uhlelo lokulawula i-PLC kumishini ekhona ukuze kuthuthukiswe ukunemba kokulawulwa kokushisa. : Ukuqapha kwangempela kwesikhathi kanye nokulungiswa kokushisa ukuze kuqinisekiswe inqubo eqinile yokuncibilika.

I-5. Ukulungiswa njalo nokuhlanza ukunciphisa i-oxidation kanye nokuguguleka

Ukuhlanza Kwansuku zonke:Sebenzisa i-scracer yokhuni noma ye-ceramic ukuze unqamule ngobumnene i-aluminium slag odongeni lwangaphakathi ukuze ugweme ukuskena ubuso beI-Ecucible for Aluminium Casting.

Ukusetshenziswa njalo kwe-antioxidant coating: Vikela ungqimba we-oxidation kusuka ekugqekeleni kancane kancane, okuthinta ukusebenza kahle kokushisa.

Gwema imvelo enomswakama:Uma kungasetshenziswa isikhathi eside, kufanele igcinwe endaweni eyomile futhi enomoya ukuvikela i-hygroscopic oxidation.
