Problems solved by technology

Especially for precision stainless steel foil products with a width of more than 500mm and a thickness of less than 0.1mm, the surface is soft, bright and low-roughness. The conventional production process will cause continuous scratches on the surface, which will affect the use of the product.
[0003] At present, there is no batch shearing process technology for the above precision stainless steel foil products, resulting in the huge demand for such products in the market cannot be effectively met

Embodiment 1

[0051] (1) Select 316L precision stainless steel foil with a width of 500 mm, a thickness of 0.1 mm, and a surface finish of BA as the raw steel coil.

[0052] (2) Load the raw steel coils onto the German B+S slitting machine. A tension pad composed of felt and flannelette is set on the raw steel coil, the surface of the flannelette is smooth, and an anti-slip bar is added. The combination of felt and fleece is to wrap a layer of fleece outside the felt to reduce the roughness of the felt and prevent the felt from scratching the steel belt. The anti-skid rod is a common steel pipe with a diameter of 30mm. One end of the flannelette is coiled and fixed on the steel pipe.

[0053] (3) Run the raw steel coil on the slitting machine. When the running of the raw steel coil does not exceed 200m, keep the initially set uncoiling tension of 30N / mm 2 , and take-up tension 30N / mm 2. When the running of the raw steel coil is greater than 200m, the coiling tension is gradually reduced...

Embodiment 2

[0060] (1) Select 316L precision stainless steel foil with a width of 550 mm, a thickness of 0.08 mm, and a surface finish of BA as the raw steel coil.

[0061] (2) Load the raw steel coils onto the German B+S slitting machine. A tension pad composed of felt and flannelette is set on the raw steel coil, the surface of the flannelette is smooth, and an anti-slip bar is added. The combination of felt and fleece is to wrap a layer of fleece outside the felt to reduce the roughness of the felt and prevent the felt from scratching the steel belt. The anti-skid rod is a common steel pipe with a diameter of 30mm. One end of the flannelette is coiled on the steel pipe and fixed. The steel pipe is fixed on the entrance frame of the upper tension pad, and the other end of the flannelette is laid flat under the tension pad.

[0062] (3) Run the raw steel coil on the slitting machine. When the running of the raw steel coil does not exceed 200m, keep the initially set uncoiling tension of...

Embodiment 3

[0069] (1) Select 316L precision stainless steel foil with a width of 580 mm, a thickness of 0.06 mm, and a surface finish of BA as the raw steel coil.

[0070] (2) Load the raw steel coils onto the German B+S slitting machine. A tension pad composed of felt and flannelette is set on the raw steel coil, the surface of the flannelette is smooth, and an anti-slip bar is added. The combination of felt and fleece is to wrap a layer of fleece outside the felt to reduce the roughness of the felt and prevent the felt from scratching the steel belt.

Abstract

The invention provides a steel strip separation method for preventing surface scratch. The method comprises the following steps: (1) a 316L precision stainless steel foil with the width of more than 500 mm and the thickness of less than 0.1 mm is selected as a raw material steel coil; (2) a tension pad composed of felt and lint is arranged on the raw material steel coil; and (3) in the running process of the raw material steel coil, the coiling tension is controlled. When the method is adopted to shear the low-roughness precision stainless steel foil with the soft and bright surface, the surface quality of the steel foil and the good actual shear edge can be achieved, the method is suitable for industrial mass production, and the high-quality requirement of the high-end industry of the precision stainless steel foil is met.

Description

technical field [0001] The present invention generally relates to the technical field of steel rolling. More specifically, the present invention relates to the field of stainless steel shearing, especially the shearing process of ultra-thin precision stainless steel strips, especially the precision stainless steel foil with a width of more than 500 mm and a thickness of less than 0.1 mm, which is a soft bright surface and low roughness. Shearing process. Background technique [0002] Ultra-thin precision stainless steel strips have now entered the fields of hydrogen energy batteries, communication semiconductors, computer products, etc., and have very high added value, which also puts forward higher requirements for the metal properties and surface quality of stainless steel. Especially for precision stainless steel foil products with a width of more than 500mm and a thickness of less than 0.1mm, the surface is soft, bright and low-roughness, the conventional production pro...
