Anealing of cold drawn steel
Iyo annealing yeinotonhora inodhonzwa simbi inowanzoshandiswa mukugadzira yekutanga kupisa kupisa maitiro.Iyo yakawanda yezvikamu zvemuchina uye engineering, mold rough inogona kubvisa kushushikana kwemukati uye kuumbwa kwekukanda, kuumba uye weldment inhomogeneity;inogona kuvandudza uye kugadzirisa simbi yemagetsi zvivakwa, uye gadziriro yesangano kune inotevera maitiro ekuita mushure mekuvhara.Kuita kwezvishoma zvinodikanwa, zvisinganyanyi kukosha zvikamu uye zvimwe zvakajairika castings, weldments, annealing inogona kushandiswa seyekupedzisira kupisa kupisa.

Iyo annealing yesimbi inopisa kune tembiricha yakakodzera, inobata imwe nguva yenguva, uye zvino inotonhorera zvishoma nezvishoma kuitira kuti iswedere pedyo nekupisa kwekupisa kwesangano rakaenzana.Chinangwa chekugadzirisa ndeye yunifomu yemakemikari kuumbwa, kuvandudza ma mechanic properties uye mashandiro ekuita, kubvisa kana kuderedza kushushikana uye kuita kuti sangano rigadzirire kupisa kwekupedzisira kwezvikamu.Iyo annealing maitiro emhando dzakawanda dzesimbi, tembiricha yekudziya inogona kukamurwa kuita mapoka maviri: imwe iri mune annealing pamusoro peiyo yakakosha tembiricha (Ac3 kana Ac1), inozivikanwawo sechikamu shanduko recrystallization annealing.Kusanganisira iyo yakanyura zvizere, yakanyura zvizere, isothermal annealing, bhora annealing uye diffusion annealing;imwe yacho iri mutembiricha yakaoma (Ac1) inotevera annealing, inozivikanwawo sekudzika-tembiricha annealing.Kusanganisira recrystallization annealing, kushushikana uye dehydrogenation annealing.Iyo nzira yekutonhodza inogona kukamurwa kuita inoenderera yekutonhodza annealing uye isothermal annealing.

Kudzima simbi inodhonzwa inotonhora
Cold drawn steel quenching inonyanya kukosha mukugadzirisa kupisa, inoshandiswa zvakanyanya maitiro.Kudzima kunogona kuvandudza zvakanyanya kusimba uye kuoma kwesimbi.Kana inofananidzwa neyakasiyana tembiricha tembiricha inogona kubvisa kana kudzikisira kudzikamisa kushushikana, asiwo simba, kuoma uye kuomarara nazvo, kusangana nezvinodiwa zvakasiyana.Naizvozvo, kudzima uye kupisa hazviparadzaniswe kubva kune maviri ekupisa kurapwa maitiro.Kudzima simbi kunopisa kusvika pamusoro penzvimbo yakakosha yakakura kupfuura yakakosha kutonhora mwero (Vc) mukudzivirira mushure mekutonhora, kuitira kuti uwane kupisa kwekupisa kwemartensite kana kuderera bainite.
