Njira zomwe zimagwiritsidwa ntchito kwambiri kuzimitsa zida zotseketsa pafupipafupi

Njira zozimitsira zomwe zimagwiritsidwa ntchito kwambiri pazida zozimitsa pafupipafupi ndi:

1. Single sing’anga kuzimitsa

Ubwino wozimitsa umodzi wapakatikati ndikuti ndi wosavuta kugwiritsa ntchito, koma ndi woyenera pazigawo zazing’ono komanso zowoneka bwino, ndipo zimakhala ndi mapindikidwe akulu komanso kusweka kwa zogwirira ntchito zazikuluzikulu.

2. Kuzimitsa kawiri sing’anga

Kuzimitsa kwapakatikati ndi kutenthetsa chogwirira ntchito kuti chitsitsimutse ndikuchimiza mkatikati mwa kuziziritsa mwamphamvu. Kusintha kwa kamangidwe ka martensite kukakhala pafupi kuchitika, nthawi yomweyo imasamutsidwa kupita ku sing’anga yokhala ndi kuzizira kofooka kuti ipitilize kuziziritsa. Nthawi zambiri, madzi amagwiritsidwa ntchito ngati njira yozimitsira mwachangu, ndipo mafuta amagwiritsidwa ntchito ngati njira yozizirira pang’onopang’ono. Nthawi zina kuzimitsa madzi ndi kuziziritsa mpweya kungagwiritsidwe ntchito. Kuzimitsa sing’anga pawiri kumatha kupewa kusokoneza kwa workpiece ndi kusweka. Zopangira zitsulo zazikulu za kaboni ndizoyenera kuzimitsa motere.

3, kutentha kwapakati

Njira yozimitsayi imachepetsa kwambiri mphamvu yozimitsa chifukwa cha kutentha kwa yunifolomu mkati ndi kunja kwa workpiece ndikumaliza kusinthika kwa martensitic pansi pazikhalidwe zoziziritsa pang’onopang’ono, motero kuchepetsa kapena kulepheretsa kusokoneza ndi kuphulika kwa workpiece, komanso kugonjetsa vuto la kulamulira madzi. ndi mafuta mu kuzima kwapawiri-zapakati. Zofooka. Komabe, chifukwa cha kutentha kwakukulu kwa sing’anga yozizira mu njira yozimitsa iyi, kuzizira kwa chogwiritsira ntchito mu bafa la alkali kapena kusamba kwa mchere kumachedwa, choncho nthawi yodikira imakhala yochepa, ndipo zimakhala zovuta kuti zigawo zazikuluzikulu ziwonongeke. kufika pamlingo wovuta wozimitsira. workpiece yaying’ono.

4. Kuzimitsa kwa isothermal

Austempering akhoza kwambiri kuchepetsa mapindikidwe ndi akulimbana workpieces, ndi oyenera pokonza zovuta, mkulu-mwatsatanetsatane ndi mbali zofunika makina, monga zisamere pachakudya, zida, ndi magiya. Monga kuzimitsira kwamagulu, kuzimitsa kwa isothermal kumatha kugwiritsidwa ntchito pazigawo zing’onozing’ono zogwirira ntchito. Zida zamakina zozimitsira ma frequency apakati komanso apamwamba zikuyenera kusankha njira yozimitsira yomwe mungagwiritse ntchito molingana ndi chogwirira ntchito chomwe muyenera kuzimitsa. Zida zing’onozing’ono zitha kuthekanso ndi kuzimitsa media imodzi.

Kuphatikiza pa njira zozimitsa zomwe zili pamwambazi pakuzimitsa zida zamakina othamanga kwambiri, njira zambiri zozimitsira zatsopano zapangidwa kuti zithandizire kulimbitsa mphamvu komanso kulimba kwachitsulo m’zaka zaposachedwa, monga kuzimitsa kutentha kwambiri, kutentha kwapang’onopang’ono kwa cyclic quenching, ndi zina.
