Indlela yokuFundisa ngokuQinisa

Ngokuqhelekileyo, ukufudumeza okutshisayo apho inani lelahleko elivuthayo liyi-0.5% okanye ngaphantsi lingaphantsi kokufudumeza kwe-oxidative, kunye nokufudumeza apho inani lelahleko elivuthayo liyi-0.1% okanye ngaphantsi libizwa ngokuba yi-non-oxidizing heat. Ukufudumeza okuncinci okungenayo i-oxidation kunokunciphisa i-oxidation yesinyithi kunye ne-decarburization, kwaye kunokuphucula kakhulu umgangatho womphezulu kunye nokuchaneka komda we-forging kunye nokunciphisa ukunxiba kokungunda. Ubuchwephesha bokufudumeza obungena-oxidation bubuchwephesha obuyimfuneko ekubumbeni ngokuchanekileyo. Okwangoku, le teknoloji ayikaqhubeki nomsebenzi omninzi wophando e-China.

 

Kukho iindlela ezininzi zokufezekisa ukufudumeza okungaphantsi kwe-oxidation. Iindlela ezisetyenziswa ngokuqhelekileyo kunye nokuphuhlisa ngokukhawuleza ukufudumeza ngokukhawuleza, ukufudumeza okuphakathi kokukhusela kunye nokushisa okuphantsi kwe-oxidizing flame.inxalenye yomatshini

 

-, ukufudumeza ngokukhawuleza

Ukufudumeza okukhawulezayo kubandakanya ukufudumeza okukhawulezileyo kunye nokufudumeza okukhawulezileyo, ukufudumeza kombane wokungeniswa, kunye nokunxibelelana nokufudumeza kombane kwisithando somlilo. Isiseko sethiyori sokufudumeza okukhawulezileyo kukuba xa intsimbi engenanto ifudunyezwa kwinqanaba lokufudumeza okunokwenzeka ngokwezobuchwepheshe, i-superposition yoxinzelelo lweqondo lokushisa, intsalela yoxinzelelo olushiyekileyo kunye noxinzelelo lwezicubu eziveliswe ngaphakathi kwibillet akwanelanga ukubangela ukuqhekeka kwebillet. Le ndlela ingasetyenziselwa ubungakanani obuncinci be-carbon steel ingots kunye nezithuba zokwenziwa ngokubanzi kweemilo ezilula. Ekubeni le ndlela ingentla inomlinganiselo ophezulu wokufudumeza, ixesha lokufudumala lifutshane, kwaye i-oxide layer eyenziwe phezu kwe-billet incinci, ukwenzela ukuba injongo ye-oxidation incinci.

Xa ukufudumala kwe-induction, inani lokutshisa intsimbi li malunga ne-0.5%. Ukuze ufezekise imfuno yokungabikho kokufudumeza kwe-oxidation, igesi yokukhusela ingangeniswa kwisithando sokufudumala sokufudumala. Igesi ekhuselayo yigesi ye-inert efana ne-nitrogen, i-argon, i-helium okanye into enjalo, kunye negesi yokunciphisa njengomxube we-CO kunye ne-H2, elungiselelwe ngokukodwa isixhobo sokuvelisa igesi ekhuselayo.cnc

Kuba ukufudumeza okukhawulezileyo kunciphisa kakhulu ixesha lokufudumeza, iqondo lokukhupha i-decarburization linokuncitshiswa kakhulu ngelixa linciphisa i-oxidation, eyahluke kakhulu ekufudumezeni kwedangatye oxidizing, enye yeenzuzo ezinkulu zokufudumeza ngokukhawuleza.inxalenye yeplastiki

 

I-2, ukufudumeza okuphakathi kokhuseleko lolwelo

 

Izinto eziqhelekileyo zokukhusela ulwelo yiglasi etyhidiweyo, ityuwa etyhidiweyo, kunye nokunye. Iziko lokufudumeza ityuwa lokuhlambela elichazwe kwicandelo lokuqala leSahluko sesi-2 luhlobo lokufudumeza okuphakathi kolwelo.

 

Umfanekiso 2-24 ubonisa uhlobo pusher semi-eqhubekayo iglasi bath eziko. Kwicandelo lokufudumeza kwesithando somlilo, ingilazi etyhidiweyo ephezulu yokushisa iyancibilika phantsi kwesithando somlilo, kwaye i-billet iyatshisa emva kokuqhutyelwa ngokuqhubekayo kwi-glass liquid. Ngenxa yokukhusela i-glass liquid, i-billet ayinayo i-oxidized ngexesha lokufudumala, kwaye emva kokuba i-billet ikhutshwe kwi-glass liquid, i-surface iphezu komhlaba. Iqhotyoshelwe kumgca omncinci wefilimu yeglasi, ayithinteli kuphela i-oxidation yesibini ye-billet, kodwa iyayithambisa ngexesha lokubumba. Le ndlela iyakhawuleza kwaye ifana nokufudumeza, ineziphumo ezilungileyo ze-oxidation kunye ne-decarburization, kwaye kulula ukuyisebenzisa, kwaye yindlela ethembisayo encinci yokufudumeza ngaphandle kwe-oxidation.
I-3, ukufudumeza okuqinileyo okuphakathi kokhuseleko (ukufudumeza kokukhusela)

 

Isambatho esikhethekileyo sisetyenziswe kwindawo engenanto. Xa ishushu, i-coating iyanyibilika ukuze yenze ifilimu edibeneyo kunye ne-airtight. Idityaniswe ngokuqinileyo kumphezulu we-blank ukwahlula indawo engenanto kwi-oxidizing furnace gas ukukhusela i-oxidation. Emva kokuba i-billet ikhutshwe, i-coating inokuthintela i-oxidation yesibini kwaye ibe nefuthe lokufudumala ukushisa, elinokuthintela ukuhla kweqondo lokushisa kwi-billet kwaye inokusebenza njenge-lubricant ngexesha lokubumba.

 

Ingubo yokukhusela ihlukaniswe ibe yiglasi yeglasi, i-glass ceramic igubungele, i-glass metal coating, i-metal coating, i-composite coating, kunye nokunye okufana nokubunjwa kwayo. Eyona nto isetyenziswa kakhulu yingubo yeglasi.

 

Iingubo zeglasi kukumiswa kokwakheka okuthile komgubo weglasi, kunye nesixa esincinci sokuzinzisa, isibophelelo kunye namanzi. Ngaphambi kokusetyenziswa, indawo engenanto kufuneka ihlambuluke nge-sandblasting, njl., ukwenzela ukuba umphezulu wengubo kunye nokungenanto inokudityaniswa ngokuqinileyo. Izinto zokwaleka zisetyenziswa ngokugquma idiphu, ibrashi yokwaleka, ukutshiza ngompu wokutshiza kunye nokutshiza nge-electrostatic. I-coating iyadingeka ukuba ifane. Ubukhulu bufanelekile. Ngokuqhelekileyo, yi-0.15 ukuya ku-0.25 mm. Ukuba i-coating inzima kakhulu, kulula ukuyikhupha, kwaye incinci kakhulu ukukhusela. Emva kokugquma, iyomiswa ngokwemvelo emoyeni ize ifakwe kwi-oven yomisa iqondo eliphantsi lobushushu ukuze yomiswe. Kwakhona kunokwenzeka ukutshisa i-billet malunga ne-120 ° C ngaphambi kokugubungela, ukwenzela ukuba ipowder emanzi yome ngokukhawuleza emva kwesicelo, kwaye ibambelele kakuhle kwindawo engenanto. Ukufudumala kwangaphambili kunokwenziwa emva kokuba iingubo zomile.

 

Ukuze unikeze ukukhuselwa okulungileyo kunye ne-lubrication yeglasi yokukhusela i-glass, i-coating kufuneka inyibilike ngokufanelekileyo, i-viscous kunye ne-chemicals stable. Xa iireyishini ezahlukeneyo zokusasazwa kweglasi zihlukile, iipropathi ezingentla zomzimba kunye neekhemikhali ziyahluka. Ngoko ke, ukusetyenziswa kuxhomekeke kuhlobo lwezinto zetsimbi kunye nezinga lokushisa lokubumba. Khetha izithako zeglasi ezifanelekileyo.

 

Indlela yokufudumala yokukhusela iglasi isetyenziswe ngokubanzi kwimveliso ye-titanium alloy, insimbi engenasici kunye ne-superalloy aviation forgings e-China.
