Inqubo yokwelapha ukushisa

Inqubo yokuhlanganisa

I-Annealing inqubo yokwelapha ukushisa lapho izinsimbi nama-alloys kushiselwa khona kuze kufike ezingeni lokushisa elifanele, kugcinwe isikhathi esithile, bese kupholiswa kancane kancane. Ngemva kokucwiliswa, insimbi ye-hypoeutectoid i-ferrite ne-pearlite ephukile; insimbi ye-eutectoid noma insimbi ye-hypereutectoid iyi-granular pearlite. Ngamafuphi, isakhiwo esine-anealed yisakhiwo esiseduze nesimo sokulinganisa.

Inhloso yokwehlisa

①Yehlisa ubulukhuni bensimbi futhi uthuthukise ipulasitiki ukuze kube lula ukusika nokuguquguquka okubandayo.

② Cwenga okusanhlamvu, susa ukukhubazeka kwesakhiwo okubangelwa ukubunjwa, ukubumba nokushisela, ukwenza ukwakheka nokwakheka kwensimbi kufane, thuthukisa ukusebenza kwensimbi noma ulungise isakhiwo sokwelashwa kokushisa okulandelayo.

③ Susa ukucindezeleka kwangaphakathi ensimbi ukuvimbela ukuguquguquka nokuqhekeka.
