Ukufakwa kwensimbi edonsayo ebandayo
I-annealing yensimbi edonsayo ebandayo ivame ukusetshenziswa ekukhiqizeni inqubo yokwelapha ukushisa kokuqala.Iningi izingxenye umshini nobunjiniyela, isikhunta rough kungaqeda ukucindezeleka kwangaphakathi kanye nokwakheka Casting, forging kanye weldment inhomogeneity;ingathuthukisa futhi ilungise izakhiwo zemishini yensimbi, kanye namalungiselelo enhlangano enqubo elandelayo ezokwenziwa ngemva kokuhushulwa.Ukusebenza kwezingxenye ezingafuneki kangako, ezingabalulekile kangako kanye nokunye okusansimbi okujwayelekile, ukushisela, ukufakwa kwe-anneal kungasetshenziswa njengokwelashwa kokushisa kokugcina.

I-annealing yensimbi ifudunyezwa ekushiseni okufanelekile, ibambe isikhathi esithile, bese ipholiswa kancane kancane ukuze isondele enqubweni yokwelapha ukushisa yenhlangano elinganiselayo.Inhloso ye-annealing iwukwakheka kwamakhemikhali okufanayo, ukuthuthukisa izakhiwo zemishini nokusebenza kwenqubo, ukuqeda noma ukunciphisa ingcindezi nokwenza inhlangano ilungele ukwelashwa kokushisa kokugcina kwezingxenye.Inqubo ye-annealing iyizinhlobo eziningi zensimbi, izinga lokushisa lokushisa lingahlukaniswa ngezigaba ezimbili: esisodwa sise-annealing ngaphezu kwezinga lokushisa elibucayi (Ac3 noma i-Ac1), eyaziwa nangokuthi i-phase change recrystallization annealing.Kubandakanya ukujula okuphelele, okufakwe ngokugcwele, ukuhunyushwa kwe-isothermal, ukuhushulwa kwebhola kanye nokufakwa kwe-diffusion;enye ikwizinga lokushisa elibucayi (Ac1) kulandela ukukhishwa kwesisu, okubuye kwaziwe ngokuthi i-low-temperature annealing.Kubandakanya i-recrystallization annealing, ukucindezelwa kanye ne-dehydrogenation annealing.Indlela yokupholisa ingahlukaniswa ibe i-anneal yokupholisa eqhubekayo kanye ne-isothermal annealing.

Ukucinywa kwensimbi edonsayo ebandayo
I-Cold drawn steel quenching ibaluleke kakhulu kwinqubo yokwelapha ukushisa, izinqubo ezisetshenziswa kabanzi.Ukucisha kungathuthukisa kakhulu amandla nobulukhuni bensimbi.Uma ifaniswe nezinga lokushisa elihlukile lingaqeda noma linciphise ukucindezelwa kokucisha, kodwa namandla, ubulukhuni nokuqina, ukuze kuhlangatshezwane nezidingo ezahlukene.Ngakho-ke, ukucisha nokushisa akuhlukaniseki nenqubo yokwelapha yokushisa emibili.Ukucisha insimbi kushisiswe ngaphezu kwephuzu elibalulekile kukhulu kunezinga lokupholisa elibalulekile (Vc) ekufakweni ngemva kokupholisa, ukuze uthole inqubo yokwelapha ukushisa kwe-martensite noma i-bainite ephansi.
