Aerospace fixtures, tsheb thauj khoom, ntauwd vaj tse, nkoj, pipelines thiab lwm yam kev siv uas yuav tsum tau muaj zog, weldability thiab corrosion kuj. Xws li: aircraft qhov chaw, lub koob yees duab lo ntsiab muag, couplers, nkoj accessories thiab kho vajtse accessories, hluav taws xob accessories thiab connectors, hniav los yog ntau yam kho vajtse, pob khawm taub hau, sib nqus taub hau, nres pistons, hydraulic pistons, hluav taws xob accessories, li qub thiab valve qhov chaw.
Kev kho cua sov txheej txheem:
1. Smelting Mn yog cov hlau refractory, thiab cov smelting kub yuav tsum tswj ntawm 740-760 degree . Do sib npaug rau ntau tshaj ob zaug ua ntej ua piv txwv los xyuas kom meej tias cov hlau yog melted kiag li, qhov kub thiab txias yog qhov tseeb, thiab cov muaj pes tsawg leeg yog uniform. Tom qab nplawm, coj ib qho piv txwv los ntawm nruab nrab ntawm qhov tob ntawm cov kua txhuas thiab los ntawm ob sab ntawm lub cub tawg rau kev tsom xam. Thaum qhov kev ntsuam xyuas tsim nyog, cov qauv tuaj yeem hloov mus rau hauv qhov cub.
2. Purification thiab casting: Tom qab cov yaj yog pauv mus rau qhov cub zoo li qub, nws yog hmoov-txhaj tshuaj thiab dav hlau-refined nrog nitrogen thiab refining tus neeg sawv cev. Qhov ntsuas kub yog 735-745 degree thiab lub sijhawm yog 15 feeb. Tom qab refining, nws yog sab laug sawv ntsug rau 30 feeb. Los ntawm cov txheej txheem no, roj, slag raug tshem tawm, thiab cov yaj yog purified.
Thaum lub sij hawm casting, muaj ob lub lim dej ntawm cov pwm casting thiab lub qhov cub lub qhov ncauj. Muaj ib lub phaj lim dej ua npuas ncauj (30PPI) ntawm lub qhov cub rau qhov pom. Ua ntej casting, 14-mesh iav fiber ntau daim ntaub yog siv los lim kom tag nrho lim tawm oxides thiab slag inclusions nyob rau hauv lub yaj. Qhov ntsuas kub ntawm 6082 alloy aluminium phaj yog qhov siab (piv rau cov txheej txheem ib txwm ntawm 6063 txhuas phaj), qhov nrawm nrawm yog qhov qis, thiab cov dej ntws kuj loj heev. Cov txheej txheem saum toj no yuav tsum tau tswj hwm nruj thiab tsis tuaj yeem tshaj qhov ntau, txwv tsis pub nws yuav yooj yim ua rau tsis ua haujlwm casting.
