Embodiment 1

[0028] In order to achieve the purpose of the present invention, in one of the embodiments of the present invention, a method for preparing a metal strip for making a backlight panel of a folding screen mobile phone is provided, comprising the following steps:

[0029] S1, one rolling;

[0030] Using a 20-roll rolling mill, after 6-7 passes of rolling, the 0.225mm semi-finished steel strip is rolled into a semi-finished steel strip with a thickness of 0.17mm, and the rough grinding roll of Ra0.5-0.7um is selected as the working roll for rolling;

[0031] S2, a solid solution annealing;

[0032] The 0.17mm semi-finished steel strip after one rolling passes through the degreasing and cleaning section of the continuous annealing line, after removing the grease remaining on the surface of the semi-finished steel strip during rolling, it is dried and enters a bright annealing furnace protected by full hydrogen, with a dew point of -45~ -55°C, the annealing speed is 22m / min, the an...

Abstract

The invention discloses a preparation method of a metal belt for manufacturing a backlight plate of a folding screen mobile phone. The preparation method comprises the following steps: S1, primary rolling; S2, primary solution annealing; S3, secondary rolling; S4, secondary solution annealing; S5, tertiary rolling, wherein a semi-finished steel belt with the thickness of 0.086 mm is rolled into a finished steel belt with the thickness of 0.03 mm through seven passes of rolling by adopting a 20-roller rolling mill; S6, finished product cleaning; S7, finished product withdrawal and straightening; and S8, finished product slitting. According to the invention, a steel belt with the thickness of 0.5 mm is sequentially subjected to primary rolling, primary solution treatment, secondary rolling, secondary solution treatment, tertiary rolling, finished product cleaning, finished product withdrawal and straightening and finished product slitting treatment, wherein in the three times of rolling steps, a sand blasting surface working roller is adopted for small-pressure multi-pass rolling, and a large-inclination and small-extension flattening technology is adopted for finished product withdrawal and straightening; and the manufactured stainless steel belt is an ultra-thin and ultra-flat stainless steel belt with the thickness of 0.03 mm.

Description

technical field [0001] The invention belongs to the technical field of stainless steel processing, and in particular relates to a preparation method of a metal strip used for making a backlight plate of a folding screen mobile phone. Background technique [0002] The backlight panel is the display screen that changes the picture in front, and the backlight panel is used to manufacture liquid crystal LCD. The liquid crystal panel of the LCD liquid crystal display does not emit light, but only transmits light, so a bright illuminant must be added on the back, which is the backlight panel, which is actually a fluorescent lamp plus a reflector. [0003] Folding screen mobile phone is a kind of smart phone. The existing technology also has high technical requirements for the backlight panel of folding screen mobile phone. However, the technology of folding screen mobile phone is not yet mature. [0004] Therefore, there is an urgent need for a method for preparing a metal strip ...
