0.28mm cold rolling coils, the allocative decision of each passage cold rolling are：3.0~5.0mm → 2.0~3.5mm → intermediate annealing → 1.3~
2.3mm → 0.9~1.6mm → 0.64~1.15mm → 0.45~0.81mm → 0.32~0.57mm → 0.23~0.40mm →
0.16~0.28mm → trimming, wherein 3.0~5.0mm → 2.0~3.5mm cold rolling pass working modulus control 25~35% it
Between, remaining each cold rolling pass working modulus control is first by the cold rolling coil of 2.0~3.5mm thickness at 22.5~35.5%, intermediate annealing
It is put into annealing furnace, 4h is kept the temperature when furnace temperature being raised to 220 DEG C with 2h afterwards, 10 is kept the temperature when furnace temperature then being raised to 530 DEG C with 3h
~20h, then when furnace temperature is dropped to 460 DEG C with 2h, keep the temperature 4h, come out of the stove when furnace temperature finally being dropped to 170 DEG C, cold after intermediate annealing
2.0~3.5mm thickness cold rolling coils should be checked by rolling volume and needing air-cooled to less than 60 DEG C to be transferred to subsequently each passes, when intermediate annealing again
End face situation, checks that end socket whether using volume phenomenon whether is touched between high temperature gummed tape, whether firm, each cold rolling coil, checks stove
Whether be stained with the circulated air hood of son aluminium end and whether remove it is clean just can be into furnace annealing；
Each cold rolling pass process is required to be lubricated and cooled down using ROLLING OIL, pays attention to wiping each deflector roll in guide passage clearly, prevents
Only surface of aluminum plate has mark, glues and hinder defect；
4) paper tinsel rolls：
The cold rolling coil progress paper tinsel of 0.16~0.28mm thickness is rolled and prepares 0.05~0.095mm aluminium foils, point that each passage paper tinsel rolls
It is with scheme：0.16~0.28mm → 0.12~0.20mm → 0.09~0.15mm → 0.05~0.095mm, when each passage paper tinsel rolls
Working roll must be replaced, clear each roller wiped in guide passage, roll surface is not all right must to replace support roller；ROLLING OIL must
Must be clean, its surface must purge clean and be not allow for residual greasy dirt when being rolled up to 0.05~0.095mm thick aluminum foils, and surface is not
Allow have the scratch of elongated or discontinuity, scuffing, periodicity mark, bright wisp and any table for influencing to use of bright band, hidden bar, informal voucher
Planar defect；
5) finished products：
0.05~0.095mm thick aluminum foils are rolled into finished products are carried out in annealing furnace, protected when furnace temperature first being raised to 210 DEG C with 4h
Warm 20h, simultaneously cooled to room temperature of coming out of the stove when furnace temperature then being dropped to 170 DEG C；
Should be checked during finished products 0.05~0.095mm thick aluminum foils volume end face situation, check end socket whether using high temperature gummed tape,
Whether touch volume phenomenon between whether firm, each aluminum foil coil, check whether be stained with the circulated air hood of stove aluminium foil and whether
Removing totally just can be into furnace annealing；
0.05~0.095mm thick aluminum foils volume after finished products just becomes the tension of tableware aluminium foil, after testing the tableware aluminium foil
Intensity >=220MPa, elongation percentage >=6%, cupping >=4mm.
