Embodiment 1

[0024] Select a stainless steel strip blank with a thickness of 0.8mm for use. The stainless steel strip blank is 06Cr19Ni10 stainless steel strip blank.

[0025] Then, a rolling is performed. Using a fourteen-high precision cold rolling mill, under a rolling force of 200KN and a rolling tension of 10KN, at a rolling speed of 80m / min, a 0.8mm thick stainless steel strip billet is rolled into a semi-finished stainless steel with a thickness of 0.4mm bring. The thickness tolerance of the semi-finished stainless steel strip is -0.01mm.

[0026] After that, solution treatment is performed. Pass the above-mentioned semi-finished stainless steel strip through a continuous hydrogen-injected bright annealing furnace with a temperature of 1050° C. at a linear speed of 10 m / min, and fill the semi-finished stainless steel strip in the annealing furnace with protective gas. Then, spray hydrogen gas to the semi-finished stainless steel strip after being released from the furnace, and p...

Embodiment 2

[0033] A stainless steel strip blank with a thickness of 0.9mm is selected for use. The stainless steel strip blank is 06Cr19Ni10 stainless steel strip blank.

[0034] Then, a rolling is performed. Using a fourteen-high precision cold rolling mill, under a rolling force of 300KN and a rolling tension of 32KN, at a rolling speed of 100m / min, a 0.9mm thick stainless steel strip billet is rolled into a semi-finished stainless steel with a thickness of 0.45mm bring. The thickness tolerance of the semi-finished stainless steel strip is -0.01mm.

[0035] After that, solution treatment is performed. Pass the above-mentioned semi-finished stainless steel strip through a continuous hydrogen-injected bright annealing furnace with a temperature of 1100° C. at a linear speed of 12 m / min, and fill the semi-finished stainless steel strip in the annealing furnace with protective gas. Then, the semi-finished stainless steel strip after being released from the furnace is rapidly cooled to ...

Embodiment 3

[0042] A stainless steel strip blank with a thickness of 1.0mm is selected for use. The stainless steel strip blank is 06Cr19Ni10 stainless steel strip blank.

[0043] Then, a rolling is performed. Using a fourteen-high precision cold rolling mill, under a rolling force of 400KN and a rolling tension of 55KN, at a rolling speed of 120m / min, a 1.0mm thick stainless steel strip billet is rolled into a semi-finished stainless steel with a thickness of 0.5mm bring. The thickness tolerance of the semi-finished stainless steel strip is -0.01mm.

[0044] After that, solution treatment is performed. Pass the above-mentioned semi-finished stainless steel strip through a continuous hydrogen-injected bright annealing furnace with a temperature of 1150° C. at a linear speed of 13 m / min, and fill the semi-finished stainless steel strip in the annealing furnace with protective gas. Then, the semi-finished stainless steel strip after being released from the furnace is rapidly cooled to m...

Abstract

The invention discloses a method for producing a stainless steel band for a mobile phone, in particular relates to a method for producing the stainless steel band for processing the mobile phone shell. The method is characterized by comprising the steps of material preparation, primary rolling, solution treatment, primary cleaning, secondary rolling, secondary cleaning and straightening and withdrawal, etc. The stainless steel band produced by the method is further processed into the mobile phone shell which produces no fingerprint after being touched by hands and is beautiful. The method can meet the demand of the mobile phone shell while the production cost is reduced.

Description

technical field [0001] The invention relates to a method for producing a steel strip. Specifically, it is a production method for stainless steel strips used to process mobile phone casings. Background technique [0002] As is well known, stainless steel bands have been widely used in casings of mobile phones. At present, the production methods of stainless steel strips used to process mobile phone casings mainly include steps such as material preparation, primary rolling, annealing treatment, secondary rolling, and tension leveling. Although the stainless steel strip produced by this method can be used to process the casing of mobile phones, the surface roughness of the rolled finished stainless steel strip is also low due to the low roughness of the rolls of the rolling mill used in the secondary rolling, which is only 0.2-0.3 μm. lower. Because the surface roughness of this stainless steel belt is relatively low, only 0.2-0.3 μm, the mobile phone shell processed by thi...
