1) mune austenite isothermal shanduko dhizaini yenzvimbo yakajairwa, kureva, ingangoita 500-600 ℃, mvura iri mumhepo yefirimu nhanho, chiyero chekutonhora hachikurumidze zvakakwana, kazhinji chinokonzera kutonhora kusina kuenzana uye kusakwana kutonhora.speed forgingsuye kuumbwa kwe "soft point".Mu martensite transformation system, kureva, inenge 300-100 ℃, mvura iri munhanho yekubikira, kutonhora kunokurumidza, nyore kuita martensite shanduko yekukurumidza inokurumidza. uye kuburitsa kushushikana kwakawanda kwemukati, zvichitungamira kuforoma deformation uye kunyange kuputika.

2) Tembiricha yemvura ine simba guru pakutonhodza simba, saka inonzwa nekushanduka kwekushisa kwemukati.Sezvo tembiricha yemvura ichikwira, kutonhora kwemvura kunodonha zvakanyanya, uye tembiricha yemhando yepamusoro yekutonhora inoenda kune yakaderera tembiricha.Kana tembiricha yemvura inopfuura 30 ℃, kutonhora kunoderera zvakanyanya mumhando ye500-600 ℃, iyo kazhinji. kunotungamirira pakuoma kweforgings, asi ine zvishoma pahuwandu hwekutonhora muhuwandu hwemartensite shanduko.Kana kupisa kwemvura kuchikwira kusvika ku60 ℃, kutonhora kunoderera ne50%.

kana mvura iine gasi rakawanda (senge mvura ichangobva kuchinjwa), kana mvura yakasanganiswa netsvina isinganyungudika, semafuta, sipo, madhaka, nezvimwewo, inoderedza zvakanyanya kutonhora kwayo, saka kutariswa kwakanyanya kunofanirwa kubhadharwa pakushandiswa uye manejimendi. .
Zvinoenderana nehunhu hwekutonhodza hwemvura, mvura kazhinji H inogona kuiswa pakudzima kutonhora kwekabhoniforgings dzesimbiine diki chikamu saizi uye chimiro chakareruka.Kudzima, zvakare cherechedza: chengetedza tembiricha yemvura iri pasi pe40 ℃, yakanakisa pakati pe15 kusvika 30 ℃, uye chengetedza mvura kana kutenderera kwemvura, kuparadza iyo yekuumba pamusoro pemvura membrane, zvakare inogona kushandisa swing. workpiece panguva yekudzima (kana kuita kuti workpiece ifambe kumusoro uye pasi) nzira yekupidigura chiutsi membrane, kuwedzera dhigirii rekutonhora pakati pe500-650 ℃, iyo inotonhorera mamiriro, dzivirira kuburitsa yakapfava.
