Aluminium ntawv nyiaj rau ob chav xoom alloy 1235
Aluminium ingot ntau lawm txheej txheem
Smelting: Siv lub tshuab ua kom muaj peev xwm loj, cov kua txhuas nkag mus rau hauv lub tshuab dov los ntawm chute. Thaum lub sij hawm ntws ntawm cov kua txhuas, tus neeg sawv cev refining Ti-B tau ntxiv rau cov kab ntau lawm thaum lub sij hawm tsim khoom, yog li tsim cov nyhuv txuas ntxiv thiab zoo li qub; Ntawm qhov tod tes, graphite Lub rotor degasses thiab tso tawm slag online, thiab cov nyhuv tshem tawm slag yog tas li thiab niaj hnub;
In hard rolling, the molten aluminum melted in the first step is introduced into the rolling mill and rolled into a billet; during this process, the cooling water inlet temperature of the roller cavity is controlled at 20-23°C, the water temperature is controlled at 28-32°C, and the melt between the roll gaps is The static pressure is controlled at 0.004-0.005Mpa. Under the condition of ensuring that the surface rate of the material (100) is >95%, lub grain loj yuav tsum yog<5um, and a slab of 6.57.5mm is finally rolled out;

Aluminium ntawv nyiaj rau ob chav xoom alloy 1235
Nruab nrab dov: txias-yob lub slab dua mus rau ib tug tuab ntawm 4.5 hli, xa mus rau lub annealing rauv, thiab cua sov rau 360 degree . Tom qab 2 teev, txuas ntxiv kom sov nws mus rau 580 degree thiab khaws cia rau 18 teev kom sib npaug sib npaug kom ua tiav cov nplej loj. tusyees thiab nyob rau tib txoj kev; Tom qab ntawd txuas ntxiv txias dov rau ntawm lub tshuab txias dov mus rau 0.60mm, thiab tom qab ntawd muab tso rau hauv qhov cub tawg dua. Tshav kub rau 460 degree, ua kom sov li 5 teev, tom qab ntawd txias rau 400 degree, ua kom sov li 7 teev, thiab muab tso rau hauv nruab nrab; tom qab ntawd txuas ntxiv dov rau hauv 0.3 hli tuab li aluminium coiled paj rwb;
Lub elastic deformation ntawm kev ua haujlwm yob muaj kev cuam tshuam zoo rau aluminium ntawv ci dov. Qhov sawv ntsug tsis yog tsuas yog yuav tsum tau tiv thaiv lub siab dov, tab sis kuj tseem muaj lub siab ntxiv los ntawm ob qho kev ua haujlwm yob sib tiv tauj ib leeg dhau qhov dav ntawm cov ntawv ci. Cov ntawv ci tuab ntawm qhov kev ua haujlwm yob kev sib cuag tshwm sim tshwm sim nyob ntawm qhov sib tsoo hlau, yob txoj kab uas hla, yob ntev, yob yas, dov ntawv dav, hydraulic dabtsi yog khoov, thiab lwm yam. Feem ntau cov thickness yog nyob rau hauv {{0}}. 1-0.2 hli. Nyob rau hauv no thickness ntau, lub peev xwm los kho thickness los ntawm dov siab thiab nro poob sharply, thiab lub peev xwm los kho thickness los ntawm kev ceev nce sharply, thiab ntxiv mus ntxiv nrog txo nyob rau hauv thickness. Thaum lub aluminium coil thickness yog li 0.05mm, yob qhov sib txawv dov yuav tsis tshwm sim thaum nyias dov. Thaum lub aluminium coil nyias nyias, lub siab ua ntej lub siab yog qhov loj, qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv.
