1. Ukulungisa:
Inqubo yokwelapha ukushisa lapho izingxenye zensimbi noma zensimbi zishiswa khona zifinyelele ezingeni lokushisa elifanele ngaphezu kwe-AC3 noma i-ACM, zigcinwe isikhathi esithile, bese zipholiswa emoyeni ukuze kutholakale isakhiwo esifana ne-pearlite.
2. Ukufakwa kwe-Annealing:
Inqubo yokwelapha ukushisa lapho izingcezu zensimbi ezingasebenzi kahle zishiswa khona kufikela kuma-degrees angu-20-40 ngaphezu kwe-AC3, zigcinwe zifudumele isikhathi esithile, bese zipholiswa kancane esithandweni (noma zingcwatshwe esihlabathini noma zipholiswe kulayimu) ziye ngaphansi kwama-degrees angu-500 emoyeni.
3. Ukwelashwa kokushisa kwesisombululo esiqinile:
Inqubo yokwelapha ukushisa lapho ingxube ishiswa khona kuze kufike ekushiseni okuphezulu futhi igcinwe ekushiseni okungaguquki esifundeni sesigaba esisodwa ukuze kuncibilikiswe ngokuphelele isigaba esengeziwe esixazululweni esiqinile, bese ipholiswa ngokushesha ukuze kutholakale isisombululo esiqinile esigcwalisiwe kakhulu.
4. Ukuguga:
Ngemva kokuba ingxubevange isithole ukwelashwa kokushisa okuqinile noma ukuguqulwa kwepulasitiki ebandayo, izakhiwo zayo ziyashintsha ngokuhamba kwesikhathi lapho ibekwa ekushiseni kwegumbi noma ngaphezu kancane kwezinga lokushisa legumbi.
5. Ukwelashwa kwesisombululo esiqinile:
qeda ngokuphelele izigaba ezahlukahlukene ku-alloy, uqinise ikhambi eliqinile futhi uthuthukise ukuqina nokumelana nokugqwala, ususe ukucindezeleka nokuthamba, ukuze uqhubeke nokucubungula nokwakha
6. Ukwelashwa kokuguga:
Ukushisa nokubamba ekushiseni lapho isigaba sokuqinisa siqala khona, ukuze isigaba sokuqinisa siqale futhi siqine, kuthuthukiswe amandla.
7. Ukucima:
Inqubo yokwelapha ukushisa lapho insimbi iqiniswa khona bese ipholiswa ngesivinini esifanele sokupholisa ukuze umsebenzi uguqukele ekuguqulweni kwesakhiwo okungazinzile njenge-martensite kuyo yonke noma ngaphakathi kobubanzi obuthile besigaba esiphambene.
8. Ukulinganisela:
Inqubo yokwelapha ukushisa lapho umsebenzi ocinyiwe ushiswa khona ezingeni lokushisa elifanele ngaphansi kwephuzu elibalulekile le-AC1 isikhathi esithile, bese upholiswa kusetshenziswa indlela ehlangabezana nezidingo zokuthola isakhiwo kanye nezakhiwo ezidingekayo.
9. Ukufakwa kwe-carbonitriding ensimbini:
I-Carbonitriding inqubo yokufaka i-carbon ne-nitrogen ngasikhathi sinye engqimbeni engaphezulu yensimbi. Ngokwesiko, i-carbonitriding ibizwa nangokuthi i-cyanidation. Njengamanje, i-carbonitriding yegesi yokushisa okuphakathi kanye ne-carbonitriding yegesi yokushisa okuphansi (okungukuthi, i-nitriding yegesi ethambile) kusetshenziswa kabanzi. Inhloso eyinhloko ye-carbonitriding yegesi yokushisa okuphakathi ukuthuthukisa ubulukhuni, ukumelana nokuguguleka kanye namandla okukhathala kwensimbi. I-carbonitriding yegesi yokushisa okuphansi ikakhulukazi iwukufaka i-nitriding, futhi inhloso yayo eyinhloko ukuthuthukisa ukumelana nokuguguleka kanye nokumelana nokubamba kwensimbi.
10. Ukucima nokulungisa:
Ngokuvamile kuyisiko ukuhlanganisa ukucima kanye nokushisa okuphezulu njengendlela yokwelapha ukushisa ebizwa ngokuthi ukucima kanye nokushisa. Ukwelashwa kokucima kanye nokushisa kusetshenziswa kabanzi ezingxenyeni ezahlukene ezibalulekile zesakhiwo, ikakhulukazi lezo zinduku zokuxhuma, amabhawodi, amagiya kanye nemishayo esebenza ngaphansi kwemithwalo eshintshanayo. Ngemva kokwelashwa kokucima kanye nokushisa, kutholakala isakhiwo se-sorbite esithambile, futhi izakhiwo zaso zomshini zingcono kunezo zesakhiwo se-sorbite esijwayelekile esinobunzima obufanayo. Ubulukhuni bayo buxhomeke ekushiseni kokushisa okuphezulu futhi buhlobene nokuzinza kokushisa kwensimbi kanye nosayizi wesigaba somsebenzi, ngokuvamile phakathi kwe-HB200-350.
11. Ukushiswa:
Inqubo yokwelapha ukushisa esebenzisa izinto zokubumba ukuhlanganisa izinto ezimbili zomsebenzi ndawonye.
