Inkqubo yeVacuum Aluminium Brazing
Itekhnoloji ye-aluminiyam ye-vacuum ye-aluminiyam isebenzisa i-alloy ye-aluminium ene-melting point ephantsi kune-aluminiyam njengento yokuqhayisa.Obu buchule bufudumeza i-weldment kunye ne-solder ngaphezu kwendawo yokunyibilika ye-solder.Kodwa ngaphantsi kobushushu obunyibilikayo besiseko sesinyithi, i-solder yolwelo igcwalisa isithuba esincinci phakathi kwezinto ezimbini zokusebenza ngokungena kwaye isasazeke ngesiseko sesinyithi, ngaloo ndlela iqonda indlela yokudibanisa i-workpieces ukuba idityaniswe.
Izinto ezilungileyo zeVacuumAaluminiyamBukukrazula
①Ubushushu bokufudumala buphantsi, ngoko ke iimpawu ezibonakalayo kunye neekhemikhali zesiseko sesinyithi aziyi kuchaphazeleka okanye zibe nefuthe elincinci.
② Amawakawaka e-welds yamalungu anzima anokudityaniswa ngexesha elinye.
③Ukuguqulwa kwamalungu kuncinci, kwaye kulula ukuqinisekisa ubungakanani bendibano.
④Ukufudumeza kwindawo yesitshixo kunenzuzo ukususa igrisi kunye nefilimu ye-oxide kumphezulu wendawo yokusebenza, kunye nokuqaqamba komphezulu wamalungu emva kwe-welding ephezulu.
⑤ Akukho flux efunekayo, akukho mfuneko yokucoca emva kwe-welding.
⑥ Ukutshisa kunye nokucima (okanye unyango oluthile lobushushu) lunokwenziwa ngaxeshanye.
Iimpawu kunye nobunzima beNkqubo ye-Aluminiyam ye-Aluminiyam ye-Brazing
Ngenxa yeempawu ezizodwa kunye neekhemikhali ze-aluminium alloy, uchungechunge lobunzima kunye neempawu ziya kuvela ngexesha lenkqubo yokuqhaqha:
Iimpawu zeekhemikhali ze-aluminiyam zisebenza ngokulinganayo, kwaye ukuhambelana kwayo neoksijini kunamandla kakhulu.Emoyeni kwiqondo lokushisa, ukudibanisa i-aluminium kunye ne-oksijini kuya kwenza i-AL exineneyo2O3ifilimu enobunzima obufikelela kwi-0.1 μm.Ifilimu ye-oxide ixinene kakhulu, kwaye indawo yayo yokunyibilika iphezulu ukuya kuma-2050 ° C, idlula kakhulu iqondo lokushisa lokunyibilika kwe-aluminium alloy.Ngexesha elifanayo, kuya kuthintela ukudibanisa okulungileyo phakathi kweentsimbi, kwaye kulula ukwenza i-slag inclusions kunye nama-pores.Ngoko ke, unyango lwangaphambili lwe-welding ye-aluminium alloys kunye nokuthintela okanye ukunciphisa ukubunjwa kwefilimu ye-oxide kwimeko eshushu kubaluleke kakhulu.Ngoko ke, kubaluleke kakhulu ukugcina i-vacuum ephezulu kwisithando somlilo, ukunciphisa ukubunjwa kwefilimu ye-oxide okanye ukususa ifilimu ye-oxide ngexesha lenkqubo yokuqhafaza, ngokukodwa kwicandelo lenkqubo ye-solder melting.
Iqondo lokushisa elinyibilikayo le-aluminium-based solder liyi-50-80 ° C kuphela eyahlukileyo ukusuka kwindawo yokunyibilika kwe-alloy aluminium ephambili, kwaye indawo yokusebenza incinci.Ngoko ke, kuyimfuneko ukuba ukhethe ngokufanelekileyo i-solder kwaye unqume uluhlu lwe-melting ye-solder, kwaye ngelo xesha, i-solder kunye nesiseko sesinyithi kufuneka sibe nokumanzi kakuhle.
Ukukhethwa okuchanekileyo kokushisa okutshisayo kunye nexesha lokubamba kubaluleke kakhulu ukwenza i-brazed joint kunye nokuphucula amandla okudibanisa.
Ukuchaneka kwe-dimensional ye-brazing components kuphezulu: umzekelo, ukunyamezela kwe-dimensional ye-fin processing kulawulwa kwi-± 0.03mm ngokuhambelana namava ethu, kwaye umgangatho wendibano / ukucoca kufuneka kwakhona kulawulwe ngokungqongqo.
