High alloy simbinemazvo diki dhayamita seamless simbi pombiinenge isingashandisi yakananga quenching muitiro;Kana huwandu hweakachengetwa austenite huchinyatsodiwa, iyo yakaderera alloy simbi haizodzimwa zvakananga.Dambudziko riripo nderekuonekwa kwema ripples pamusoro pe anemazvo diki dhayamita seamless simbi pombi(zvakadai se spiral kana hypoid gears) pasi pemutoro wekushanda.
Kuti udzikise huwandu hweakachengetwa austenite uye deformation panguva yekudzima yakananga, kutonhora kwepamberi kunogona kushandiswa kusvika kuAr1 tembiricha mushure mekuvhiyiwa uye nekudzima.Iyo chaiyo dhayamita dhayamita isina musono pombi yesimbi inogona zvakare kudzimwa kutanga kana ichiendeswa kuchoto chakakwira zvishoma pane tembiricha yeAr1.Mushure mekuviga uye kudzima, iyo chaiyo diki caliber isina musono pombi inogona zvakare kudziyiswa kune tembiricha iri pamusoro pepamusoro Ac1, ichiwedzera kunatsa zviyo uye kuderedza huwandu hweyakasara austenite.
Iyo chaiyo dhayamita dikiinotonhora yakakungurutswa seamless simbi pombiinodzimwa zvakananga kuti iwane simba repamusoro uye kuoma, asi kuomarara hakuna kukwirira.Kuoma kweiyo carburized layer inogona kuyerwa nefaira.Hukukutu hunogona kudzikiswa nekuda kwekuvapo kwekusara austenite mune chaiyo diki pombi isina musono yesimbi yakakwira alloy.Iyi nzira inogonawo kuderedza simenti pamuganhu wezviyo.Paunenge uchigadzira iyo carburized pamusoro peiyo chaiyo diki caliberpombi yesimbi isina musonochinodikanwa, kunonoka kutonhora kana kuvharisa kuchagamuchirwa.
Kana simbi yakaomeswa yakakwirira yakasarudzwa kana kukanganiswa nemidziyo, kunyangwe kutonhora kuchinonoka, pamusoro pediki dhayamita chaiyo inopenya gobvu rusvingo pombi ichine kuoma kwepamusoro.Muchiitiko ichi, kurapwa kunyoro kunofanira kugamuchirwa.Kuti udzivise kunaya kwenetwork carbide, mwero wekutonhora wepakati unofanirwa kutorwa.Tora dzimwe dziviriro kudzivirira decarburization panguva inononoka kutonhora.Mvura yakadzimwa simbi ichashandiswa gare gare.Mushure mekuvhiyiwa, kutonhora kunononoka kana nzira yekudzima mafuta inogona kushandiswa kukwenenzvera zviyo pakati peiyo pombi diki isina musono pombi isina kukanganiswa kana kutsemuka.
Mukuita kupisa kwekupisa kwekudzima kwakawanda, carburizing uye kutonhora kunoteverwa nekudzimisa kudzimisa, kudzima kwepamusoro kunogona kuitika nekudzima kwepamusoro, uye nzira idzi dzinogona kushandiswa zvakare.Nezve madiki mapaipi asina musono esimbi ane yakakwira alloy zvemukati, zviri nani kutora nzira iri padyo nekunangisa kudzima, kureva, reheat kusvika 15 ~ 25 ℃ (25 ℃ ~ 50 ℃) pamusoro peiyo yepakati shanduko yekupisa tembiricha (hongu, kupfuura pamusoro pekushandura kwepamusoro).
Iyo yekupisa yekurapa maitiro inowedzera kusimba kwepakati peiyo dhayamita diki yakakwirira-chaiyo seamless pombi uye ine kusimba kwakanaka.Anenge ese ma carbides akasara ari pamusoro anonyungudika.Kunyangwe iyo yakasara austenite yemukati yemaitiro akadaro nemazvo diki dhayamita inotonhora yakakungurutswa seamless simbi pombi iri shoma pane iyo yekudzima zvakananga, inozochengetwa zvishoma.Iyo deformation yakakura kupfuura iyo yekudzima yakananga, asi mukati meiyo inogamuchirwa renji.Sekudzima kwakananga, nzira iyi haitombo shandiswe kune yakajairwa kabhoni simbi.
Mushure mekunonoka kutonhora kana kudzima, iyo simbi yemvura inogona kudzoserwa kune chikamu chekuchinja tembiricha yakakwira zvishoma pane iyo yecarburized layer.Semuenzaniso, diki dhayamita alloy precision isina musono pombi inogona kupiswazve mushure mekuvhiyiwa uye kunonoka kutonhora, nekuti haigone kunatsa zviyo uye kudzima, kuitira kuti kuoma kwayo kuve kwakaderera, deformation idiki, uye kuoma kuri pakati nepakati;Iyo yepamusoro pedenga ine isina kunyungudika carbides, saka ine yakakwirira kuoma uye brittleness;Semuenzaniso, iyo chaiyo diki pombi yesimbi isina musono inodziswa patsva mushure mekuviga uye kudzima, uye tsanga yacho inonatswa zvizere.Iyo yepakati ine yakanyanya kuomarara, yakaderera kuomarara, uye pamusoro haina network cementite, saka kuomarara kwakakwira uye kuomarara kwakanaka, asi chakashata ndechekuti deformation yakakura.
