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 muchikamu chekufashaira, chiyero chekutonhora chinokurumidza kukurumidza, nyore kuita martensite shanduko yekukurumidza inokurumidza uye inobudisa kushushikana kwakanyanya kwemukati, zvichiita kuti pave nekugadzirisa 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 ℃, izvo zvinowanzo tungamira mukuoma kwe.forgings, asi ine zvishoma pahuwandu hwekutonhora muhuwandu hwemartensite shanduko.Kana kupisa kwemvura kuchikwira kusvika ku60 ℃, kutonhora kunoderera ne50%.

kana mvura iine gasi rakawanda (semvura ichangobva kuchinjwa), kana mvura yakasanganiswa netsvina isinganyungudika, semafuta, sipo, madhaka, nezvimwewo, ichaderedza zvakanyanya kutonhora kwayo, saka kutarisisa kwakanyanya kunofanirwa kubhadharwa kune kushandiswa uye manejimendi.
Zvinoenderana nehunhu hwekutonhodza hwemvura, mvura kazhinji H inogona kuiswa pakudzima kutonhora kwekabhoniforgings dzesimbiine diki chikamu saizi uye nyore shape.Quenching, anofanirawo kucherechedza: chengeta mvura tembiricha pazasi 40 ℃, yakanakisisa pakati 15 kusvika 30 ℃, uye chengeta mvura kana mvura kutenderera, kuparadza forging pamusoro pemvura chiutsi membrane, uyewo anogona kushandisa swing workpiece panguva quenching (kana kuita workpiece inofamba kumusoro uye pasi) nzira yekupidigura 0 0 dhigirii inotonhorera, kuwedzera 0 0 dhigirii, kuwedzera 0 dhigirii 6, kuwedzera 0 ℃. kutonhora mamiriro, dzivisa kuburitsa nyoro.
