Stainless steel explosion-proof material suitable for acid chemicals and preparation method thereof

Abstract

The invention provides a stainless steel explosion-proof material and a preparation method thereof. The preparation process of the explosion-proof material comprises the following steps: rolling a stainless steel band; cutting joints by a joint cutter; and stretching to form a mesh material, wherein the stainless steel comprises the following chemical elements in percentage by mass: less than or equal to 1.00% of silicon, less than or equal to 1.00% of manganese, less than or equal to 0.025% of phosphorus, less than or equal to 0.015% of sulphur, 0.10-0.16% (preferably 0.12-0.16%) of carbon, 2.00-3.00% of nickel, and 15.00-17.00% (preferably 15.00-16.50%) of chromium. The thickness of the stainless steel band is 0.03-0.10 mm, preferably 0.05-0.07 mm. The laser beam emitted by the joint cutter is basically vertical to the moving direction of the stainless steel band, the total power for emitting laser rays is 100-1,000 watts, and 3-5 parallel laser ray emitting devices are used for cutting joints.

Description

technical field [0001] The invention relates to an explosion-proof material, especially a stainless steel explosion-proof material suitable for acidic chemicals and a preparation method thereof. Background technique [0002] In the storage and transportation containers of flammable and explosive liquid and gaseous hazardous chemicals, in order to prevent the medium from burning and exploding due to accidents such as static electricity, open flames, gunshots, etc., it is necessary to fill a kind of mesh explosion-proof material in the storage and transportation containers. Material. Existing explosion-proof materials are made of aluminum alloy. This explosion-proof material has been immersed in the container medium for a long time, and its application range is limited due to the material itself. In addition, the current explosion-proof materials are generally made by cutting slits on the metal foil by mechanical cutting technology, and then stretched. The cutting waste and ...

AI Technical Summary

Problems solved by technology

This explosion-proof material has been immersed in the container medium for a long time, and its application range is limited due to the material itself.

In addition, the current explosion-proof materials generally use mechanical cutting technology to cut slits on the metal foil, and then stretch it. The cutting waste and particles generated during cutting are unfavorable for the use of explosion-proof materials.

To sum up, the existing explosion-proof materials have some defects in material selection and processing technology, which cannot meet the application requirements of some special fields and need to be improved.
