Forging Heating Method

Kazhinji, kupisa kwekugadzira uko kuwanda kwekupisa kurasikirwa kuri 0.5% kana kushoma ishoma oxidative, uye kudziyisa umo huwandu hwekupisa kurasikirwa kuri 0.1% kana kushoma kunonzi kusiri-oxidizing kupisa. Kudziyisa kushoma-isina oxidation kunogona kuderedza simbi oxidation uye decarburization, kuvandudza zvakanyanya kunaka kwepamusoro uye dhimensional kurongeka kwefogi, uye kuderedza kupfeka mold. Ishoma oxidation-yemahara yekudziya tekinoroji ndiyo yakakosha kutsigira tekinoroji yekunyatso kuforoma. Iyi tekinoroji haisati yaita tsvagiridzo yakawanda muChina.

 

Pane nzira dzakawanda dzekuwana kushoma oxidation-isina kudziyisa. Nzira dzinowanzo shandiswa uye dzinokurumidza kukura dzinokurumidza, dziviriro yepakati, uye kushomeka kwemoto kupisa.machining chikamu

 

1, kupisa nekukurumidza

Kukurumidza kupisa kunosanganisira kupisa nekukurumidza uye kumhanyisa kupisa, induction yemagetsi kupisa, uye kubata magetsi kupisa muvira remoto. The theoretical hwaro hwekukurumidza kudziyisa ndeyekuti kana simbi isina chinhu ichidziiswa pahunyanzvi hwekupisa mwero, iyo yepamusoro yekushushikana kwekushisa, kusara kunetseka, uye kushushikana kwematishu kunogadzirwa mukati mebillet hakuna kukwana kukonzera kutsemuka kwebillet. Iyi nzira inogona kushandiswa kune diki-saizi kabhoni simbi ingots uye blanks kune yakajairika forging yeakareruka maumbirwo. Sezvo nzira iri pamusoro apa ine kupisa kwakanyanya, nguva yekupisa ipfupi, uye oxide layer inoumbwa pamusoro pebillet yakaonda, saka chinangwa che oxidation idiki.

Kana induction heat inoshandiswa, kupisa kwesimbi kunenge 0.5%. Gasi rinodzivirira rinogona kuunzwa muchoto chekupisa chemukati kuti chiwane chinodiwa chekusapisa oxidation kupisa. Iyo inodzivirira gasi igasi inert senge nitrogen, argon, helium, kana zvimwe, uye gasi rinoderedza senge musanganiswa weCO neH2, yakanyatsogadzirirwa nemudziviriro wekugadzira gasi.CNC

Sezvo kupisa nekukurumidza kunopfupisa nguva yekudziya, dhigirii re decarburization rinogona kudzikiswa zvakanyanya uku ichidzikisa oxidation, iyo yakasiyana neiyo shoma oxidizing kupisa kwemoto, imwe yezvakakosha zvakanakira kupisa nekukurumidza.chikamu chepurasitiki

 

2, mvura yepakati kudzivirira kudziyisa

 

Standard liquid kudzivirira midhiya igirazi yakanyungudutswa, yakanyungudutswa munyu, etc. Munyu kugeza choto kudziyisa inorondedzerwa muchikamu chekutanga Chitsauko 2 imhando yemvura yepakati kudzivirira kudziyisa.

 

Mufananidzo 2-24 inoratidza pusher-mhando semi-inopfuurira girazi yekugezera choto. Muchikamu chekupisa chechitofu, girazi rakanyungudutswa rakanyungudutswa rinonyungudutswa pasi pechoto, uye billet inopisa mushure mekuramba ichisundirwa kuburikidza negirazi remvura. Nekuda kwekudzivirirwa kwegirazi remvura, iyo billet haina oxidized panguva yekupisa, uye mushure mekunge billet ichisundirwa kunze kwegirazi remvura, iyo nzvimbo iri pamusoro. Yakasungirirwa kune yakaonda yegirazi firimu, inodzivirira yechipiri oxidation yebillet uye inoizora panguva yekugadzira. Iyi nzira inokurumidza uye yakafanana mukudziya, ine yakanaka oxidation uye decarburization mhedzisiro, iri nyore kushanda, uye inovimbisa kushoma oxidation-isina kupisa nzira.
3, yakasimba yepakati kudzivirira kudziyisa (coating kudzivirira kudziyisa)

 

Mushonga unokosha unoshandiswa pamusoro pechinhu chisina chinhu. Kana ichipisa, iyo yekuputira inonyunguduka kuita dense uye airtight coating film. Yakasungirirwa zvakasimba pamusoro pechisina kuvharwa kuti iparadzanise isina chinhu kubva kune oxidizing choto gasi kudzivirira oxidation. Mushure mekunge billet yaburitswa, iyo yekupfekedza inogona kudzivirira yechipiri oxidation uye ine kupisa-inodzivirira mhedzisiro, kudzivirira iyo billet yepasi tembiricha kudonha uye kuita semafuta panguva yekugadzira.

 

Iyo inodzivirira yakavharwa yakakamurwa kuita girazi rejasi, girazi resimbi yeramic, girazi resimbi yesimbi, simbi yesimbi, inoumbwa nekubatanidza, uye zvakafanana zvinoenderana nekuumbwa kwayo. Inonyanya kushandiswa ndiyo girazi rekuvhara.

 

Girazi mabhandi ekumisikidzwa kweimwe gadziriso yegirazi poda pamwe neshoma yekudzikamisa, binder, uye mvura. Usati washandiswa, pamusoro pechinhu chisina chinhu chinofanira kucheneswa nejecha rejecha, nezvimwewo, kuitira kuti nzvimbo yekuputira uye isina chinhu inogona kusungwa zvakasimba. Mabatiro anoshandiswa ne dip coating, brush coating, spraying gun spraying, uye electrostatic spraying. Iyo yekupfeka inodiwa kuti ive yunifomu. Ukobvu hwakakodzera. Kazhinji, iri 0.15 kusvika 0.25 mm. Kana iyo yakanyanyisa kukora, zviri nyore kupepeta uye yakaonda zvakanyanya kudzivirira. Mushure mekuputira, inoomeswa zvakasikwa mumhepo uye inoiswa muchoto chepasi-kupisa. Izvo zvakare zvinokwanisika kupisa billet kusvika 120 ° C isati yapfekedzwa kuitira kuti hupfu hwakanyorova huomeswe pakarepo mushure mekushandisa uye kunamatira zvakanaka pamusoro pechinhu chisina chinhu. Iyo pre-forging heat inogona kuitwa mushure mekuputira kwaoma.

 

Iyo yekupfekedza inofanirwa kunyungudutswa zvakakwana, yakaomeswa, uye yakagadzika kemikari kuti ipe dziviriro ine musoro uye mafuta egirazi rekudzivirira. Kana mareshiyo akasiyana ekugovera egirazi akasiyana, iwo emuviri uye emakemikari zvimiro zvakasiyana. Naizvozvo, kushandiswa kunoenderana nerudzi rwesimbi inoshandiswa uye tembiricha yekugadzira. Sarudza zvakakodzera girazi zvigadzirwa.

 

Iyo girazi yekudzivirira yekudzivirira nzira yekudziya yakashandiswa zvakanyanya muChina kugadzira titanium alloy, simbi isina tsvina, uye superalloy aviation forgings.
