Inqubo yokwelapha ukushisa kwepayipi lensimbi elingenamthungo iyindlela ebalulekile yokuthuthukisa izakhiwo zalo zemishini, izakhiwo zomzimba kanye nokumelana nokugqwala. Okulandelayo yizinqubo eziningana ezivamile zokwelapha ukushisa kwamapayipi ensimbi angenamthungo:
Ukufakwa kwe-Annealing
- Inqubo: Ukufaka i-Annealing kuhilela ukushisaipayipi lensimbi elingenamthungoekushiseni okuthile, ukuyibamba kulelo zinga lokushisa isikhathi esithile, bese iphola kancane kancane.
- Inhloso: Umgomo oyinhloko ukunciphisa ubulukhuni kanye nokuqhekeka ngenkathi kwandiswa ukuguguleka kanye nokuqina. Kuphinde kuqede ukucindezeleka kwangaphakathi okubangelwa ngesikhathi sokukhiqiza. Ngemva kokufakelwa, isakhiwo esincane siba yinto efanayo, okwenza kube lula ukucubungula nokusetshenziswa okulandelayo.
Ukulungisa
- Inqubo: Ukulungisa kuhilela ukushisa ipayipi lensimbi elingenamthungo ngaphezu kwe-Ac3 (noma i-Acm) ngo-30 ~ 50°C, ulibambe kuleli zinga lokushisa isikhathi esithile, bese ulipholisa emoyeni ngemva kokulikhipha esithandweni.
- Inhloso: Njengokunamathela, ukujwayeza kuhlose ukuthuthukisa isakhiwo esincane kanye nezakhiwo zemishini zepayipi. Kodwa-ke, amapayipi ajwayelekile abonisa ubulukhuni namandla aphezulu ngezakhiwo ezicolekile, okwenza afaneleke ukusetshenziswa okudinga ukusebenza okuphezulu kwemishini.
Ukucima
- Inqubo: Ukucima kuhilela ukushisa ipayipi lensimbi elingenamthungo liye ezingeni lokushisa elingaphezu kwe-Ac3 noma i-Ac1, ulibambe kuleli zinga lokushisa isikhathi esithile, bese ulipholisa ngokushesha liye ezingeni lokushisa legumbi ngesivinini esisheshayo kunesivinini sokupholisa esibalulekile.
- Inhloso: Inhloso eyinhloko ukufeza isakhiwo se-martensitic, ngaleyo ndlela kuthuthukiswe ubulukhuni namandla. Kodwa-ke, amapayipi acishiwe avame ukuba buthakathaka futhi athambekele ekuqhekekeni, ngakho-ke ngokuvamile adinga ukushiswa ngemva kwalokho.
Ukulinganisela
- Inqubo: Ukushisa kuhilela ukuphinda kufudumale ipayipi lensimbi elingenamthungo lifinyelele ezingeni lokushisa elingaphansi kwe-Ac1, ulibambe kuleli zinga lokushisa isikhathi esithile, bese ulipholisa lifinyelele ezingeni lokushisa legumbi.
- Inhloso: Inhloso eyinhloko ukunciphisa ukucindezeleka okusele, ukuzinzisa isakhiwo esincane, ukunciphisa ubulukhuni kanye nokuqhekeka, kanye nokuthuthukisa ukuqina kanye nokuqina. Kuye ngokushisa okushisa, ukufudumala kungahlukaniswa ngokushisa okuphansi, ukushisa okuphakathi, kanye nokushisa okuphezulu.
Lezi zinqubo zokwelapha ukushisa zingasetshenziswa zodwa noma zihlanganiswe ndawonye ukuze kufezwe ukusebenza kwepayipi lensimbi okufiswayo. Ekukhiqizeni kwangempela, inqubo efanele yokwelapha ukushisa kufanele ikhethwe ngokuya ngokusetshenziswa kanye nezidingo ezithile zepayipi lensimbi elingenamthungo.
