Magiya a zitsulo za ufa ndi zinthu zosinthidwa makonda, malinga ndi zofunikira zosiyanasiyana zamachitidwe, ndizofanana ndi kutentha wamba.Pambuyo pakuwotcha ndi kuzimitsidwa, ayenera kutenthedwa kuti achepetse kupsinjika kwamkati ndikuzimitsa brittleness, kukhazikika kwake, ndikukwaniritsa zofunikira zamakina.Kutentha kochepa kumachitidwa kawirikawiri.Mitundu itatu ya kutentha kwa induction, kutentha kwa ng'anjo ndi kudziletsa nthawi zambiri amagwiritsidwa ntchito popanga.
①Kutentha kwa induction Chogwiritsira ntchito chozimitsidwa chimatenthedwanso kuti chikwaniritse cholinga cha kutentha, ndiye kuti, chogwirira ntchito chikatenthedwa ndi inductor ndikuzirala, kutentha kwa induction ndi kutentha kuyenera kuchitika nthawi yomweyo.Chifukwa cha nthawi yochepa yotentha, microstructure imakhala ndi kubalalikana kwakukulu.Itha kupeza kukana kwamphamvu kwambiri komanso kulimba kwambiri, etc. Ndikoyenera kwambiri kutenthetsa ma shafts, manja ndi mbali zina zomwe zimatenthedwa mosalekeza ndikuzimitsidwa.
②Kutentha mu ng'anjo Chogwiritsira ntchito chimatenthedwa mu ng'anjo ya dzenje, ng'anjo yamafuta kapena zida zina pambuyo pozimitsa kwambiri.The tempering kutentha ayenera kutsimikiziridwa molingana ndi kuuma chofunika ndi ntchito, ndi kutentha kutentha ndi Time, monga mkulu mpweya zida zitsulo ndi zipangizo kuyeza, sing'anga mpweya zitsulo kapena sing'anga mpweya aloyi zitsulo magiya ndi spline mitsinje, aloyi kuponyedwa chitsulo camshafts ndi mbali zina. , amafuna kuzirala kocheperako, nthawi zambiri pogwiritsa ntchito kuzirala komiza m'madzi kapena m'madzi.Ambiri aiwo amatenthedwa pa 150 ~ 250 ℃, ndipo nthawi imakhala 45 ~ 120min.Amagwiritsidwa ntchito kwambiri pa tempering ya workpieces ndi kukula yaying'ono, mawonekedwe ovuta, khoma woonda ndi wosaya oumitsa wosanjikiza kuonetsetsa kuuma mkulu ndi kuvala kukana pamwamba pa mbali.Amafuna.
③Kudziletsa Lekani kuziziritsa pambuyo kupopera mbewu mankhwalawa kapena kumiza kuzirala, ndi ntchito kutentha alipo mkati mwa workpiece kuzimitsidwa pambuyo kuzimitsidwa kuti quenching zone kukwera kwa kutentha kwina kachiwiri kukwaniritsa zofunika tempering, ndi kutentha kwake kuyenera kukhala apamwamba kuposa kutentha kutentha. m'ng'anjo.Nthawi zambiri, mkati mwa zigawozo zimakhala ndi kutentha kwakukulu pambuyo pozizira kwa masekondi 3 mpaka 10.Monga nthawi yodziletsa, zigawo zazikulu ndi 6s ndipo zing'onozing'ono ndi 40s kuti amalize kudziletsa.
