magawo atatu kuzungulira zitsulo kuzimitsa ndi tempering kupanga mzere zida.

1. Kuzimitsa siteji ya induction Kutentha ng’anjo

The quenching siteji ya magetsi oyatsira moto imakonzedwa kumbuyo kwa chotenthetsera chotenthetsera ng’anjo yamoto ndipo imakhala ndi njira yoziziritsira madzi yozungulira. Pamene zinthu za bar zimatenthedwa ndi kutentha kozimitsa, zimatuluka mu ng’anjo yotenthetsera yotentha, ndipo kugwiritsa ntchito moyenera komanso kothandiza kwa zida zoziziritsira madzi zozungulira kungapangitse kuti zinthu za bar ziziziziritsidwa mwamphamvu pano. Pamwamba pa bar, mtengo wozizira umaposa mtengo wovuta wa martensite, kotero kuti martensite angapangidwe pamwamba kuti akwaniritse cholinga chozimitsa.

2. Gawo lotenthetsera la ng’anjo yotenthetsera induction

Chozimitsidwa cha bar katundu chimanyamulidwa ndi makina otumizira ku ng’anjo yotenthetsera kuti itenthetse. Pambuyo pofika kutentha kwa kutentha, baryo amachotsedwa mu ng’anjo yotenthetsera ndi tebulo lozungulira. Chophimbacho chimawululidwa ndi mpweya, ndipo kutentha kwapakati kudzakhudzidwa. Kusamukira pamwamba wosanjikiza ndi kutentha pamwamba kukwaniritsa cholinga kutentha.

3. Gawo lozizirira la ng’anjo yotenthetsera induction

Gawoli limachitika kenako, makamaka austenite pachimake amakumana ndi kusintha kwa isothermal kuti apeze gawo lomaliza la kapangidwe ka metallographic.

Round zitsulo kuzimitsa ndi kutentha ndi njira yabwino kuwongolera khalidwe, amene angathe kusintha kapangidwe mkati mwa chidutswa adagulung’undisa, kuti apeze bwino mawotchi mphamvu. Chithandizo cha kutentha kwapaintaneti kwa chinthu chogubuduzika chikhoza kupanga mawonekedwe a martensite pamtunda pozimitsa, ndipo kupyolera mu kutentha kwapakati pa kutentha, pamwamba pa martensite ndi kudziletsa, kotero kuti pamwamba pake amatha kupeza mawonekedwe a martensite. Pachimake ali lalikulu kutentha dontho chifukwa kuzirala pamwamba wosanjikiza, amene amayenga dongosolo pearlite kwaiye, amene osati kumawonjezera kuuma pamwamba wosanjikiza, komanso bwino pachimake dongosolo. Komanso, Intaneti kuzungulira zitsulo quenching ndi kutentha akhoza kumapangitsanso katundu makina a mbale zitsulo ndi kuchepetsa zili mpweya ndi aloyi zinthu. Kuchiza kutentha kwapaintaneti kumaphatikiza kutentha koyendetsedwa, kugudubuzika koyendetsedwa ndi kuziziritsa kokhazikika kukhala njira yonse yopanga mphamvu yopulumutsa mphamvu, kotero imatha kupulumutsa mphamvu zambiri ndikuchepetsa ndalama.
