1, mune yakajairika chikamu austenitic isothermal shanduko dhiyagiramu, kureva, anenge 500-600 ℃, mvura iri mumhepo firimu nhanho, uye kutonhora kumhanya hakusi kukurumidza zvakakwana, izvo zvinowanzo tungamira kune "soft point" inoumbwa nekusaenzana kutonhora uye kusakwana kutonhora kumhanya kwefogi. nhanho, iyo yekutonhora inomhanya inokurumidza, iri nyore kuita iyo martensitic shanduko yekumhanyisa inokurumidza uye inoburitsa huwandu hukuru hwekushushikana kwemukati, zvichikonzera kuforoma deformation kana kuputika.

2, tembiricha yemvura ine pesvedzero huru pakutonhora kwesimba, saka inonzwa kune shanduko yeambient tembiricha. Sezvo tembiricha yemvura ichiwedzera, kutonhora kwemvura kunodzikira zvakanyanya, uye tembiricha yemhando yepamusoro yekutonhora inoenda kune yakaderera tembiricha.Kana tembiricha yemvura ichipfuura 30 ℃, kumhanya kwekutonhora mumhando ye500-600 ℃ inoderera zviri pachena, izvo zvinowanzoita kuti kuumbwa kurege kuomeswa, asi kune simba shoma pakutonhora kwekutonhora mukati meiyo 6 tembiricha yemvura inotonhorera inosimudzwa. chiyero chichadzikira neinenge 50%.

3, kana mvura ine gasi rakawanda (semvura nyowani), kana mvura yakasanganiswa netsvina isinganyungudika, semafuta, sipo, madhaka, nezvimwewo, inoderedza zvakanyanya kugona kwayo kutonhora, saka kushandiswa uye manejimendi kunofanirwa kutariswa zvakanyanya.
Maererano kutonhora maitiro emvura, mvura H inogona kushandiswa quenching uye kutonhora kabhoni simbi forgings ane diki chikamu saizi uye nyore shape.Quenching, anofanirawo kucherechedza: chengeta mvura tembiricha pazasi 40 ℃, yakanakisisa pakati 15 kusvika 30 ℃, uye kuchengeta mvura kana mvura kutenderera, kuparadza forging pamusoro chiutsi membrane, kanawo anogona kushandisa chidimbu chebasa chipfunga chipfunga chipfunga chipfunga, uye anogona kushandisa chidimbu chekushanda pasi pechipfunga chekushanda uye kusimudza chidimbu chekushanda. kukanganisa membrane yemhepo, wedzera dhigirii yekutonhora pakati pe500-650 ℃, mamiriro ekutonhora, dzivirira kuburitsa yakapfava.

Kubva: 168 forgings net
