Cov txheej txheem luv luv ntawm cov txheej txheem ntau lawm rau ultra-thin aluminium ntawv ci, uas yog tus cwj pwm hauv qhov nws tau ua raws li cov txheej txheem hauv qab no:
Thawj kauj ruam, smelting: Siv lub qhov cub loj-muaj peev xwm regenerative smelting rauv los hloov cov txhuas raw rau hauv molten aluminium, uas nkag mus rau hauv casting thiab dov zeb los ntawm ib tug ntxhua khaub ncaws. Thaum lub sij hawm khiav ntawm cov molten txhuas, cov refiner Al-Ti-B tau ntxiv hauv online los tsim kom muaj kev sib txuas ntxiv thiab zoo li qub; lub graphite rotor degasses thiab tshem tawm slag online ntawm 730-735 degree, tsim ib tug nruam thiab uniform tshem tawm cov nyhuv;
The second step, rough rolling: The molten aluminum melted in the first step is introduced into the casting and rolling mill to cast and roll into a billet; during this process, the inlet temperature of the cooling water in the roller body cavity is controlled at 20-23°C, and the outlet water temperature is controlled at 20-23°C. 28-32℃, the static pressure of the aluminum melt between the roll gaps is controlled at 0.004-0.005Mpa, ensuring that the crystallization direction {100} area ratio of the material is >95%, lub grain loj yog tsawg dua los yog sib npaug rau 5μm, thiab ib tug slab ntawm 6.5-7.5mm yog dov. ;
Qhov thib peb kauj ruam, nruab nrab dov: Yob cov saum toj no-hais slab dua nrog lub txias dov chav tsev. Thaum lub thickness ncav cuag 4.5 hli, xa mus rau lub qhov cub annealing, kub rau 360 degree, cia nws sov li 2 teev, thiab tom qab ntawd mus rau qhov kub ntawm 580 degree. , ua kom sov li 18 teev, ua homogenization annealing kom cov nplej loj sib xws thiab coj mus sib xws; Tom qab ntawd txuas ntxiv txias yob nws nyob rau hauv lub txias dov zeb mus rau 0.60mm, ces xa mus rau lub annealing rauv dua, sov nws mus rau 460 degree, thiab cia nws sov rau 5 teev tom qab ntawd, qhov kub thiab txias yog txo mus rau 400 degree, khaws cia rau 7. teev, thiab nruab nrab annealing yog ua; ces txuas ntxiv dov mus rau lub thickness ntawm 0.3 hli yog siv raws li txhuas ntawv ci ntaub plaub;
Kauj Ruam 4: Foil dov: Siv plaub-cov menyuam irreversible ntawv ci dov zeb dov saum toj no 0.3 hli txhuas ntawv ci ntaub 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 tsawg, thiab cov peev txheej tsim khoom me me. Qhov zoo ntawm ultra-thin aluminium ntawv ci tsim tuaj yeem ncav cuag qib siab thoob ntiaj teb. Piv nrog rau cov txheej txheem kub-rolling ntau lawm, tus nqi peev hauv kev tsim cov blanks yog txo. Ob feem peb, cov nqi khiav hauj lwm raug txo los ntawm ntau tshaj ib nrab.
