Embodiment 1

[0015] The process of this embodiment uses stainless steel cold-rolled coils as raw materials, with a thickness of 0.50 mm and a width of 406 mm, and the thickness of the finished steel strip after cold rolling is 0.15 mm.

[0016] The present invention adopts following processing steps:

[0017] 1. Firstly, the raw material of stainless steel cold-rolled coil with a thickness of 0.50mm is cold-rolled once with a 20-high Sendzimir rolling mill. The lubricating coolant used in cold rolling is "DAPHNE STAINLESS ROLL P-T" rolling oil provided by Changzhou Guohong Chemical Co., Ltd., and the temperature of the rolling oil is 30°C. The surface roughness of the working rolls of the rolling mill is Ra0.10μm, and they are cold-rolled to a thickness of 0.167mm after 7 passes. The tension after the first pass is 13kg / mm 2 , front tension 22kg / mm 2 , Mill speed 80 m / min. After that, the front and rear tension of each pass should be 28~48kg / mm 2 Increment by pass, the rolling mill sp...

Embodiment 2

[0032] The process of this embodiment uses stainless steel cold-rolled coils as raw materials, with a thickness of 0.90mm and a width of 406mm, and the thickness of the finished steel strip after cold rolling is 0.30mm.

[0033] The present invention adopts following processing steps:

[0034]1. Firstly, the raw material of stainless steel cold-rolled coil with a thickness of 0.90mm is cold-rolled once with a 20-high Sendzimir rolling mill. The lubricating coolant used in cold rolling is "DAPHNE STAINLESS ROLL P-T" rolling oil provided by Changzhou Guohong Chemical Co., Ltd., and the temperature of the rolling oil is 35°C. The surface roughness of the working rolls of the rolling mill is Ra0.20μm, and they are cold-rolled to a thickness of 0.338mm after 6 passes. The tension after the first pass is 14kg / mm 2 , front tension 25kg / mm 2 , The rolling mill speed is 70 m / min. After that, the front and rear tension of each pass should be 28~48kg / mm 2 Increment by pass, the roll...

Embodiment 3

[0049] The process of this embodiment uses stainless steel cold-rolled coils as raw materials, with a thickness of 1.50 mm and a width of 616 mm. The thickness of the finished steel strip after cold rolling is 0.50 mm.

[0050] The present invention adopts following processing steps:

[0051] 1. Firstly, the raw material of stainless steel cold-rolled coil with a thickness of 1.50mm is cold-rolled once with a 20-roller Sendzimir rolling mill. The lubricating coolant used in cold rolling is "DAPHNE STAINLESS ROLL P-T" rolling oil provided by Changzhou Guohong Chemical Co., Ltd., and the temperature of the rolling oil is 40°C. The surface roughness of the working rolls of the rolling mill is Ra0.25μm, and they are cold-rolled to a thickness of 0.56mm after 6 passes. The tension after the first pass is 15kg / mm 2 , front tension 28kg / mm 2 , Mill speed 60 m / min. After that, the front and rear tension of each pass should be 28~48kg / mm 2 Increment by pass, the speed of each pass...

Abstract

The invention relates to a process for producing an accurate stainless steel band applied in an electronic industry. The process comprises the following steps of: the first cold rolling process; the first spray degreasing process; the first hot-water spraying process; the first hot-wind drying and solid dissolving process; the second cold rolling process; the second spray degreasing process; the second hot-water spraying process; and the second hot-wind drying process, bending stretching and straightening process and the process of cutting into finished products. According to the production process, a twenty-Hi sendzimir rolling mill and an unique rolling process are adopted for cold rolling; and the processes such as degreasing, solid dissolving treatment, bending stretching, straightening, and the like are performed, so that the product has little tolerance fluctuation of the thickness, stable performance, uniform surface color and roughness and no color difference, good plate flatness, improved quality and capacity of meeting the requirements of the electronic industry on top quality.

Description

technical field [0001] The invention relates to a production process of a precision stainless steel strip widely used in processing accessories of mobile phones, computers and electronic products. Background technique [0002] At present, the precision stainless steel strips used in the electronics industry are rolled by multi-roll mills, and other auxiliary equipment are used to improve the surface and flatness of the plate. However, the stainless steel strips made by the existing technology have large fluctuations in thickness tolerance. , Unstable mechanical properties, uneven surface color and roughness, poor flatness of the plate shape and other shortcomings. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a production process for precision stainless steel strips that can produce stable performance, small fluctuations in thickness tolerance, uniform surface color and roughness without...
