Izvo zvakanyanya kuipa kwemvura sekudzima uye kutonhora svikiro kune forgings ndezvi:

1, mune yakajairwa chikamu cheaustenitic isothermal transition diagraph, kureva, inenge 500-600 ℃, mvura iri munhanho yefirimu remhepo, uye kumhanya kwekutonhora hakumhanyire zvakakwana, izvo zvinowanzotungamira kune "soft point" inoumbwa ne kutonhora kusina kuenzana uye kusakwana kwekutonhora kwekumhanya kwekugadzira.Mu martensitic transformation system, kureva, inenge 300-100 ℃, mvura iri munhanho yekubikira, kutonhora kunokurumidza kukurumidza, nyore kuita martensitic shanduko yekukurumidza inokurumidza uye. buritsa huwandu hukuru hwekushushikana kwemukati, zvichikonzera kuforoma deformation kana kutopwanya.

2, tembiricha yemvura ine pesvedzero huru pakutonhora kwesimba, saka inonzwa kune shanduko yeambient tembiricha. Sezvo tembiricha yemvura ichiwedzera, kutonhora kwemvura kunoderera zvakanyanya, uye tembiricha yemhando yepamusoro yekutonhodza inoenda kune yakaderera tembiricha.Kana tembiricha yemvura inopfuura 30 ℃, kumhanya kwekutonhora mumhando ye500-600 ℃ inoderera zviri pachena, izvo kazhinji. kunotungamirira kukugadzira kuti kurege kuomeswa, asi kune simba shoma pakukurumidza kutonhora muhuwandu hwemartensite shanduko.Kana tembiricha yemvura inosimudzwa kusvika 60 ℃, kutonhora kunoderera ne50%.

kuumba, pombi flange, treaded flange, simbi flange, oval flange, Slip on flange, forged blocks, Weld neck flange, lap joint flange,orifice flange, flange inotengeswa, forged round bar, lap joint flange, forged pombi fittings. ,neck flange,Lap joint flange

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 kudzima uye kutonhora kwekabhoni simbi forgings ine diki chikamu saizi uye nyore shape.Quenching, inofanirawo kucherechedza: chengetedza tembiricha yemvura pazasi 40 ℃, iyo 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 ichikwira nekudzika) nzira yekupidigura membrane yemhepo, kuwedzera dhigirii yekutonhora pakati pe500-650. ℃, iyo yekutonhora mamiriro, dzivirira kuburitsa yakapfava poindi.
