Ultra-thin ntau lawm txheej txheem ntawm ntim aluminium foil

1. Melting: Siv lub tshuab hluav taws xob loj uas muaj peev xwm rov ua dua smelting rauv kom yaj cov thawj txhuas rau hauv molten aluminium, thiab nkag mus rau hauv lub tshuab casting thiab dov los ntawm kev ntxhua khaub ncaws. Thaum lub sij hawm khiav ntawm cov molten txhuas, cov refiner Al-Ti-B tau ntxiv hauv online los tsim kev ua kom zoo thiab tsis tu ncua. Cov nyhuv: Lub graphite rotor degasses thiab tshem tawm slag online ntawm 730-735 degree, tsim ib qho kev tshem tawm tsis tu ncua thiab zoo ib yam.
2. Rough rolling: the molten aluminum after the first step of smelting is introduced into the casting and rolling machine to be cast and rolled into billets; during this process, the cooling water inlet temperature of the inner cavity of the roller is controlled at 20-23°C, and the outlet water temperature is controlled at 28-28°C. 32°C, the static pressure of the aluminum melt between the roll gaps is controlled at 0.004-0.005Mpa, to ensure that the crystallization direction {100} area ratio of the material is >95 feem pua, cov nplej loj yog tsawg dua los yog sib npaug rau 5μm, thiab ib lub slab ntawm 6.5-7.5mm yog dov.
3. Intermediate dov: Cov lus hais saum toj no yog dov dua los ntawm lub tshuab txias dov, thiab thaum nws ncav cuag lub thickness ntawm 4.5 hli, nws raug xa mus rau hauv lub qhov cub annealing, rhuab mus rau 360 degree, thiab khaws cia rau 2 teev, tom qab ntawd txuas ntxiv mus rau 580 degree, khaws cia sov li 18 teev, ua homogenization annealing kom cov nplej loj sib xws thiab cov kev taw qhia zoo ib yam; Tom qab ntawd txuas ntxiv mus rau txias-yob rau hauv lub txias dov zeb mus rau 0.60 hli, xa mus rau hauv lub qhov cub annealing dua, kub rau 460 degree C, thiab cia rau 5 teev. Txo qhov kub mus rau 400 degree, ua kom sov li 7 teev, thiab ua qhov nruab nrab annealing; Tom qab ntawd txuas ntxiv dov mus rau lub thickness ntawm 0.3 hli raws li txhuas ntawv ci ntaub plaub.
4. Ntawv nyiaj dov: siv plaub-roller irreversible foil rolling unit los yob lub saum toj no-hais txog 0.3 hli aluminium foil wool rau hauv cov ntawv txhuas tiav. Cov txheej txheem ntau lawm ntawm ultra-nyias aluminium ntawv ci yog luv luv, tus nqi khiav lag luam yog tsawg, thiab cov peev txheej tsim khoom me me, thiab qhov zoo ntawm ultra-thin aluminium ntawv ci tuaj yeem ncav cuag qib siab tshaj plaws thoob ntiaj teb. Piv nrog rau cov txheej txheem ntau lawm ntawm cov txheej txheem kub dov, cov nqi peev hauv kev tsim cov blanks yog txo ob feem peb, cov nqi khiav lag luam txo qis dua li ib nrab.
