Indlela yokuFundisa ngokuQinisa

Ngokuqhelekileyo, ukufudumeza ukutshisa apho inani lelahleko elivuthayo li-0.5% okanye ngaphantsi lingaphantsi kwe-oxidative, kwaye ukufudumeza 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, iphucula kakhulu umgangatho womphezulu kunye nokuchaneka komda we-forging, kunye nokunciphisa ukunxiba kokungunda. Ubuchwephesha bokufudumeza obungena-oxidation bubuchwephesha obuyimfuneko ekubumbeni ngokuchanekileyo. Le teknoloji ingekaqhubeki uphando oluninzi e-China.

 

Kukho iindlela ezininzi zokufezekisa ukufudumeza okungaphantsi kwe-oxidation. Iindlela ezisetyenziswa ngokuqhelekileyo kunye nokuphuhlisa ngokukhawuleza, ukhuseleko oluphakathi, kunye nokufudumeza okuncinci kwe-oxidizing flame.inxalenye yomatshini

 

1, 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 elinokwenzeka lobushushu obunokwenzeka, i-superposition yoxinzelelo lobushushu, uxinzelelo olushiyekileyo, kunye noxinzelelo lwethishu oluveliswe ngaphakathi kwibillet alwanelanga ukubangela ukuqhekeka kwebillet. Le ndlela ingasetyenziselwa ama-ingots ensimbi yekhabhoni encinci kunye nezithuba zokubumba ngokubanzi kweemilo ezilula. Ekubeni le nkqubo ingentla inomlinganiselo ophezulu wokufudumeza, ixesha lokufudumala lifutshane, kwaye i-oxide layer eyenziwe kwindawo ye-billet incinci, ngoko ke injongo ye-oxidation incinci.

Xa kusetyenziswa ukufudumeza kwe-induction, ukutshisa insimbi malunga ne-0.5%. Igesi ekhuselayo ingangeniswa kwisithando sokufudumala se-induction ukufezekisa imfuno yokungabikho kwe-oxidation yokufudumeza ukufudumeza. 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 le-decarburization lingancitshiswa kakhulu ngelixa linciphisa i-oxidation, eyahluke kakhulu kwi-oxidizing flame heat, enye yeenzuzo ezibalulekileyo zokufudumeza ngokukhawuleza.inxalenye yeplastiki

 

I-2, ukufudumeza okuphakathi kokhuseleko lolwelo

 

Imithombo yeendaba yokhuselo lolwelo olusemgangathweni yiglasi etyhidiweyo, ityuwa etyhidiweyo, njl.njl. Iziko lokufudumeza ityuwa lokuhlambela elichazwe kwicandelo lokuqala leSahluko se-2 luhlobo lobushushu obuphakathi bokhuseleko.

 

Umfanekiso we-2-24 ubonisa i-pusher-type semi-continuous glass bath furnace. Kwicandelo lokufudumeza kwesitofu, ingilazi etyhidiweyo ephezulu yobushushu 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. Incanyathiselwe kumgca omncinci wefilimu yeglasi, ikhusela i-oxidation yesibini ye-billet kwaye iyithambise ngexesha lokubumba. Le ndlela iyakhawuleza kwaye iyafana ekufudumezeni, ineziphumo ezilungileyo ze-oxidation kunye ne-decarburization, 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, ukuphepha ukwehla kweqondo lokushisa kwi-billet kwaye isebenze 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 nexabiso elincinci lokuzinzisa, 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 ngemipu, 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 iyancipha kakhulu ukukhusela. Emva kokugquma, yomiswa ngokwemvelo emoyeni kwaye ifakwe kwi-oven ephantsi. Kwakhona kunokwenzeka ukutshisa i-billet malunga ne-120 ° C ngaphambi kokugquma ukwenzela ukuba ipowder emanzi yome ngokukhawuleza emva kwesicelo kwaye ibambelele kakuhle kwindawo engenanto. Ukufudumala kwangaphambili kunokwenziwa emva kokuba iingubo zomile.

 

Ingubo kufuneka inyibilike ngokwaneleyo, ixinene, kwaye izinzile ngokwekhemikhali ukubonelela ngokhuseleko olufanelekileyo kunye ne-lubrication yengubo yokukhusela yeglasi. Xa iireyishini ezahlukeneyo zokusasazwa kweglasi zihlukile, iipropathi ezibonakalayo kunye neekhemikhali ziyahluka. Ngoko ke, ukusetyenziswa kuxhomekeke kuhlobo lwezinto zetsimbi ezisetyenzisiweyo kunye neqondo lokushisa lokubumba. Khetha izithako zeglasi ezifanelekileyo.

 

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