Embodiment 1

[0007] The stainless steel is rolled into a 0.03mm thick stainless steel strip, and the mass % of each chemical element contained in the stainless steel is carbon ≤ 0.025, silicon ≤ 1.00, manganese ≤ 1.00, phosphorus ≤ 0.040, sulfur ≤ 0.030, nickel ≤ 1.00, nitrogen ≤ 0.035 , chromium 17.00, molybdenum 1.50. Slit the stainless steel belt with a laser device, and stretch it to form a mesh explosion-proof material. The cutting equipment used is a laser slitting machine, the power of the laser head of the slitting machine is 100 watts, and the cutting speed is 200mm / s. Stretch forming is operated by a stretching machine, and the stretched mesh is at an angle of 70-90 degrees to the original plane.

Embodiment 2

[0009] The operation of Example 1 was repeated, except that the mass % of certain chemical elements was modified to 17.50 for chromium and 1.75 for molybdenum. The thickness of the stainless steel strip is modified to 0.05mm.

Embodiment 3

[0011] The operation of Example 1 was repeated, except that the mass % of certain chemical elements was modified to 18.00 chromium and 2.00 molybdenum, and the thickness of the stainless steel strip was modified to 0.07 mm.

Abstract

The invention provides a stainless steel anti-explosion material and a manufacturing method thereof. The manufacturing process of the anti-explosion material comprises the following steps of: rolling a stainless steel belt; cutting the stainless steel belt with a joint cutter to form slots; and stretching the stainless steel belt to form a meshy material, wherein the stainless steel belt containsthe following chemical elements in percentage by mass: less than or equal to 0.025 percent of carbon, less than or equal to 1.00 percent of silicon, less than or equal to 1.00 percent of manganese, less than or equal to 0.040 percent of phosphorus, less than or equal to 0.030 percent of sulfur, less than or equal to 1.00 percent of nickel, less than or equal to 0.035 percent of nitrogen, 17.0 to 19.0 percent, preferentially 17.5 to 19.0 percent of chromium, and 1.50 to 2.00 percent, preferentially 1.75 to 2.00 percent of molybdenum; and the thickness of the stainless steel belt is 0.03 to 0.10mm, preferentially 0.05 to 0.07mm. Laser beams emitted by the joint cutter are vertical to the moving direction of the stainless steel belt substantially; the total power for emitting laser rays is 100 to 1,000W; and 3 to 5 parallel laser ray emitting devices are used for cutting slots.

Description

technical field [0001] The invention relates to an explosion-proof material, especially a stainless steel explosion-proof material suitable for medicine and food 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...
