Yakakwana Ongororo Uye Hurukuro Yemajenareta

(1) Kukuvadza kwemabhandeji tishu

Mhedzisiro yekuongororwa kwemetallographic yakaratidza kuti pakanga paine kupatsanurwa kwenzvimbo mune izvo zvinhu.Band microstructure ndiyo microstructure inoumbwa pamwe chete neinotenderera nzira yesimbi, inonyanya kuumbwa neproeutectoid ferrite uye pearlite.Nekuda kweiyo mikrostructure yakasiyana-siyana uye zvivakwa zvemabhendi ari padyo, kusungirirwa kwekunetseka kunozoitika pakati pemabhendi akasimba uye asina kusimba, zvichikonzera kudzikira kwese kwemaitiro emagetsi uye anisotropy iri pachena.Pasi pekuita kwesimba rekunze, delamination kubvarura kunoitika zviri nyore pamwe neiyo strip chimiro, iyo inoisa hwaro hwekutadza kwekutanga kwezvinhu.

(2) Mabviro ezvivakwa zvakasungwa

Strip chimiro chimiro chakajairika chakaremara mune yakaderera kabhoni simbi, iyo inokonzerwa nezvikonzero zviviri: chekutanga, iyo yakasarudzika crystallization yesimbi yakanyungudutswa panguva yekristalllization process yesimbi ingot inotungamira kune kusaenzana kugoverwa kwedendrite chimiro.Munguva yekukunguruka, iyo coarse dendrite inorebesa uye zvishoma nezvishoma inosangana negwara re deformation, nekudaro ichigadzira iyo superposition yeakapera uye akafumiswa mabhandi ekabhoni uye alloy zvinhu.Mukuita kwekunonoka kutonhora, ferrite uye pearlite inonyanya kusungirirwa zvivakwa.Muchiitiko ichi, kuumbwa kwebhandi ndiyo hwaro uye chinodiwa chetishu banding.Saka zvakajairwa annealing normalizing zvakaoma kubvisa, chete kuburikidza nepamusoro tembiricha diffusion annealing uye normalizing kamwe kana katatu kuvandudza kana kubvisa.

Chikonzero chechipiri isangano rebhabhoni rinokonzerwa nekombiyuta isina kunaka yekushanda.Kana kupisa kunopisa kunopisa kuri munzvimbo yezvikamu zviviri, ferrite inonaya kubva ku austenite mumabhandi pamwe chete nesimbi inoyerera, uye iyo isina kuvharwa austenite inokamurwa kuita mabhandi.Kana yatonhodzwa kuenda kuA1, bhendi austenite inoshanduka kuita banded pearlite.Banded zvimiro zvinogona kuvandudzwa uye kubviswa ne normalizing kana annealing.

(3) Kuedza kwekuenzanisa kwekubvisa bhandi chimiro

Kuti uone chikonzero chekuparadzaniswa kwebhendi uye kuibvisa, 20 simbi yakagadziriswa maererano neyakajairwa kupisa kupisa.Iyo yakagadziriswa metallographic chimiro (ona FIG. 6) yakaratidza kuti bhandi chimiro che scaffold chakavandudzwa zvakanyanya, zvichiratidza kuti bhanhire rakasungirirwa re scaffold rakakonzerwa nemaitiro asina kunaka ekupisa kupisa, izvo zvinogona kuvandudzwa uye kubviswa mushure mekugadzirisa zvakakodzera kurapwa.Naizvozvo, iyo yemukati inokonzeresa yekuputsika kwescaffold uye matanho ekuvandudza ayo anotsvakwa kubva pachikamu chezvinhu microstructure.

(4) Kuongorora kwakadzama

Kubva pakugadzira uye kugadziriswa kwechimiro chekunze kwechigadziro, chimiro chese chebhakiti chakashata, weld iri pachena, mavanga emapanga nemakomba zvinogona kuonekwa kwose kwose, zvichiratidza kuti hutano hwese hwekugadzirisa hauna kunaka.Sezvinogona kuonekwa kubva pakugadzirisa uye nzvimbo yekuputsika kwerutsigiro muFIG.1, kuputsika kwakaitika pakona yemahwendefa esimbi akatwasuka uye akatwasuka, ayo pakutanga aive asina kusimba chinongedzo mukugadzirwa kwemaitiro.Panofanirwa kuve nearc yekuchinja nzvimbo yekudzikisa kushushikana, asi kune akasiyana machining matanho.Kukanganisa kwekugadzira kwakajeka kwakadaro pasina mubvunzo kunotungamira kunzvimbo dzekushushikana, izvo zvinovhura nzira dzekutanga crack uye budiriro.

Panyaya yehunyanzvi hwekugadzirisa tekinoroji yerutsigiro, simbi inopisa-yakakungurutswa haina kujaira isati yashandiswa, kana inoenderana yemuviri uye kemikari yekuongorora bvunzo, zvichikonzera kuti mbishi zvinhu zvine hurema hwechimiro zviendeswe kune inotevera kugadzirisa maitiro.Pamusoro pezvo, simbi yesimbi yerutsigiro haina kuvharwa kana kuti yakajairika mushure mekucheka, izvo zvinozotungamira kune kuvepo kwewelding zvakasara kushushikana uye nekumhanyisa brittle fracture process yerutsigiro kusvika pamwero wakati.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. yakavambwa muna 2006, inogadzira dhiziri jenareta muChina, iyo inobatanidza dhizaini, kupa, kutumira uye kugadzirisa. dhiziri jenareta set .Products cover Cummins , Perkins, Volvo, Yuchai, Shangchai, Deutz, Ricardo, MTU, Weichai nezvimwewo zvine simba renji 20kw-3000kw, uye vave yavo OEM fekitari uye tekinoroji centre.
