1) mune austenite isothermal shanduko mepu yenzvimbo yakajairwa, kureva, ingangoita 500-600 ℃, mvura iri mumhepo yefirimu nhanho, kutonhora kumhanya hakumhanyire zvakakwana, kazhinji kunokonzera kusaenzana.forgingkutonhora uye kusakwana kutonhora kumhanya uye kuumbwa kwe "soft point".Mu martensite transformation system, kureva, inenge 300-100 ℃, mvura iri munhanho yekuvira, kutonhora kunokurumidza kukurumidza, nyore kuita martensite shanduko yekukurumidza inokurumidza uye inobudisa kushushikana kwakanyanya kwemukati, zvichiita kuti the forging deformation uye kunyange kuputika.
2) Tembiricha yemvura ine simba guru pakutonhodza simba, saka inonzwa nekushanduka kwekushisa kwemukati.Sezvo tembiricha yemvura inokwira, simba rekutonhodza rinodonha zvakanyanya, uye tembiricha yemhando yepamusoro yekutonhora inoenda kune yakaderera tembiricha.Kana tembiricha yemvura ichipfuura 30 ℃, mwero wekutonhora unodzikira zvakanyanya mumhando ye500-600 ℃, izvo zvinowanzo tungamira mukuoma kweforgings, asi ine mhedzisiro shoma pachiyero chekutonhora muhuwandu hwemartensite shanduko.Kana tembiricha yemvura yakwira kusvika pa60℃, mwero wekutonhora unodzikira ne50%.
3) kana mvura iine gasi rakawanda (semvura ichangobva kuchinjwa), kana mvura yakasanganiswa netsvina isinganyungudika, semafuta, sipo, madhaka, nezvimwewo, inoderedza zvakanyanya kutonhora kwayo, saka kushandiswa uye manejimendi kunofanirwa kutarisisa. ku.
Zvinoenderana nehunhu hwekutonhodza hwemvura, mvura kazhinji H inogona kuiswa pakudzima kutonhora kwekabhoni simbiforgingsnekukura kwechikamu chidiki uye chimiro chiri nyore.Kudzima, inofanirawo kucherechedza: chengetedza tembiricha yemvura iri pasi pe40 ℃, iyo yakanakisa pakati pe15 kusvika 30 ℃, uye chengetedza mvura kana kutenderera kwemvura, kuparadzaforgingpamusoro pemvura membrane, zvakare inogona kushandisa swing workpiece panguva yekudzima (kana kuita kuti workpiece ifambe kumusoro nekudzika) nzira yekupidigura membrane yeutsi, kuwedzera kutonhora kuri pakati pe500-650 ℃, kutonhora mamiriro, kudzivirira kuburitsa yakapfava.
