Forging Heating Indlela

Ngokuvamile, ukushisisa kwe-forging lapho inani lokulahlekelwa okuvuthayo kungu-0.5% noma ngaphansi ukushisisa okune-oxidative okuncane, futhi ukushisisa lapho inani lokulahleka kokuvutha kungu-0.1% noma ngaphansi kubizwa ngokuthi ukushisisa okunga-oxidizing.Ukushisisa okuncane okungena-oxidation kunganciphisa i-oxidation yensimbi kanye ne-decarburization, futhi kungathuthukisa kakhulu ikhwalithi yangaphezulu kanye nokunemba kobukhulu bokubumba futhi kunciphise ukuguga kwesikhunta.Ubuchwepheshe bokushisisa obungena-oxidation obuncane buwubuchwepheshe obusekelayo obuyisisekelo bokufoja okunembayo.Njengamanje, lobu buchwepheshe abukadingi ukwenza umsebenzi omningi wocwaningo eChina.

 

Kunezindlela eziningi zokufinyelela ukushisisa okuncane okungena-oxidation.Izindlela ezivame ukusetshenziswa nezithuthuka ngokushesha ukushisa okusheshayo, ukufudumeza okuphakathi kokuvikela kanye nokushisa komlilo oxidizing kancane.imishini ingxenye

 

-, ukushisa ngokushesha

Ukushisa okusheshayo kuhlanganisa ukufudumeza okusheshayo kanye nokudlulisa ukushisa okusheshayo, ukufudumeza kukagesi okungeniswayo, nokuxhumana nokushisa kukagesi esithandweni somlilo.Isisekelo sethiyori sokushisa okusheshayo siwukuthi lapho insimbi engenalutho ishiswa ngesilinganiso sokushisa okungenzeka ngokobuchwepheshe, ukuphakama okuphezulu kokucindezeleka kwezinga lokushisa, ukucindezeleka okusalayo okusele kanye nokucindezeleka kwezicubu ezikhiqizwa ngaphakathi kwe-billet akwanele ukubangela ukuqhekeka kwe-billet.Le ndlela ingasetshenziselwa ama-ingots ensimbi ekhabhoni anosayizi omncane kanye nezikhala zokubunjwa okujwayelekile kobumo obulula.Njengoba le ndlela engenhla inezinga eliphezulu lokushisa, isikhathi sokushisa sifushane, futhi ungqimba lwe-oxide olwakhiwe ebusweni be-billet luncane, ukuze inhloso ye-oxidation incane.

Lapho ukushisa kwe-induction, inani lokushiswa kwensimbi lingaba ngu-0.5%.Ukuze kuzuzwe imfuneko yokungabikho kokushisisa kwe-oxidation, igesi evikelayo ingangeniswa esithandweni sokushisa sokungeniswa.Igesi evikelayo iyigesi engasebenzi njenge-nitrogen, i-argon, i-helium noma okunye okunjalo, kanye negesi enciphisa njengengxube ye-CO ne-H2, elungiselelwe ngokukhethekile idivayisi ekhiqiza igesi evikelayo.cnc

Njengoba ukushisisa okusheshayo kusifinyeza kakhulu isikhathi sokushisa, izinga le-decarburization lingancishiswa kakhulu ngenkathi kunciphisa i-oxidation, ehluke kancane ekushiseni kwelangabi oxidizing, okungenye yezinzuzo ezinkulu kakhulu zokushisisa ngokushesha.ingxenye yepulasitiki

 

2, liquid medium ukuvikelwa Ukushisa

 

Imidiya evamile yokuvikela uketshezi ingilazi encibilikisiwe, usawoti oncibilikisiwe, nokunye okunjalo.Ukushisa kwesithando sokugeza usawoti okuchazwe esigabeni sokuqala seSahluko sesi-2 kuwuhlobo lokushisa okuphakathi kokuvikela okuwuketshezi.

 

Umfanekiso 2-24 ubonisa uhlobo lwepusher uhlobo lokugeza ingilazi semi-eqhubekayo.Esigabeni sokushisa sesithando somlilo, ingilazi encibilikisiwe ephezulu yokushisa iyancibilika ngaphansi kwesithando, futhi i-billet iyashiswa ngemva kokuqhutshwa ngokuqhubekayo emanzini engilazi.Ngenxa yokuvikelwa koketshezi lwengilazi, i-billet ayinayo i-oxidized ngesikhathi senqubo yokushisa, futhi ngemva kokuba i-billet iphushelwe ngaphandle koketshezi lwengilazi, ingaphezulu lingaphezulu.Enamathiselwe ungqimba oluncane lwefilimu yengilazi, ayivimbeli kuphela i-oxidation yesibili ye-billet, kodwa futhi iyayigcoba ngesikhathi sokubumba.Le ndlela iyashesha futhi iyafana ekushiseni, inemiphumela emihle ye-oxidation kanye ne-decarburization, futhi kulula ukuyisebenzisa, futhi iyindlela yokushisa engena-oxidation ethembisayo kancane.
3, ukufudumeza okuqinile kokuvikela okuphakathi (ukushisa kokuvikela ukuvikela)

 

I-coating ekhethekile isetshenziswa ebusweni be-blank.Uma kushisa, ukumboza kuyancibilika ukuze kwakheke ifilimu enamathelayo eqinile futhi engenamoya.Iboshelwe ngokuqinile endaweni engenalutho ukuze ihlukanise okungenalutho esithandweni somlilo esine-oxidizing ukuvimbela ukufakwa kwe-oxidation.Ngemuva kokuthi i-billet ikhishwe, i-coating ingavimbela i-oxidation yesibili futhi ibe nomphumela wokushisa ukushisa, okungavimbela ukwehla kokushisa okungaphezulu kwe-billet futhi kungenza njenge-lubricant ngesikhathi sokubumba.

 

Ingubo evikelayo ihlukaniswe yaba ingilazi enamathelayo, ingilazi yokugqoka i-ceramic, ingilazi yensimbi yensimbi, i-metal coating, inhlanganisela eyinhlanganisela, nokunye okufanayo ngokuvumelana nokwakheka kwayo.Okusetshenziswa kakhulu yi-glass coating.

 

Izingubo zengilazi ukumiswa kokwakheka okuthile kwempushana yengilazi, kanye nenani elincane le-stabilizer, i-binder namanzi.Ngaphambi kokusetshenziswa, indawo engenalutho kufanele ihlanzwe nge-sandblasting, njll, ukuze ubuso be-coating kanye nokungenalutho kuhlanganiswe ngokuqinile.Izembatho zisetshenziswa ngokugcotshwa kwediphu, ukugcotshwa kwebhulashi, ukufutha ngesibhamu sesifutho kanye nokufutha nge-electrostatic.I-coating iyadingeka ukuze ifane.Ugqinsi lufanelekile.Ngokuvamile, i-0.15 kuya ku-0.25 mm.Uma ukunamathela kuwugqinsi kakhulu, kulula ukuxebuka, futhi mncane kakhulu ukuba ungawuvikela.Ngemva kokuyimboza, iyomiswa ngokwemvelo emoyeni bese ifakwa kuhhavini wokomisa izinga lokushisa eliphansi ukuze yomiswe.Kungenzeka futhi ukushisa i-billet kuze kufike ku-120 ° C ngaphambi kokumboza, ukuze i-powder emanzi isomile ngokushesha ngemva kokufaka isicelo, futhi ibambelele kahle ebusweni bendawo engenalutho.Ukushisa kwangaphambi kokubumba kungenziwa ngemuva kokumiswa kokugcoba.

 

Ukuze unikeze ukuvikeleka okuhle nokugcotshwa kwengubo yokuvikela ingilazi, ukugqoka kufanele kuncibilike kahle, kube ne-viscous futhi kuzinzile ngamakhemikhali.Lapho izilinganiso zokusabalalisa ezihlukahlukene zengilazi zihlukile, izakhiwo ezingenhla zomzimba namakhemikhali zihlukile.Ngakho-ke, ukusetshenziswa kuncike ohlotsheni lwempahla yensimbi kanye nezinga lokushisa lokubumba.Khetha izithako zengilazi ezifanele.

 

Indlela yokushisa yokuvikela ukumboza ingilazi isetshenziswe kabanzi ekukhiqizeni ingxubevange ye-titanium, insimbi engagqwali kanye ne-superalloy aviation forgings e-China.
