Embodiment Construction
[0018] Such as figure 1 Shown is a kind of manufacturing process of improving the anticorrosion performance of 430 stainless steel plate of the present invention, comprises the steps:
[0019] Material preparation in Kaiping: According to customer requirements, cut 430 stainless steel 2B flat plates of required specifications;
[0020] Grinding and polishing: in the wet, high-speed mirror grinding machine, through repeated grinding, the grinding head speed is 1400-2000 rpm, and the matte layer on the surface of 430 stainless steel is removed to achieve the 8K mirror effect;
[0021] Cleaning: Put the polished 430 stainless steel plate on the crawler-type flat plate cleaning line, and carry out the residual cleaning treatment of the surface polishing liquid, and then process it later.
[0022] Drying: Pass the cleaned 430 stainless steel plate through the squeeze sponge roller to remove the surface water.
[0023] Inspection: Before vacuum coating, check whether the board is ...

The invention discloses a manufacturing process for promoting antiseptic property of stainless steel materials, comprising the steps of preparing materials, grinding and polishing, cleaning, drying, checking, PVD vacuum plating and adhering film for package. The PVD vacuum plating comprises the processes of: A) loading 430 stainless steel specular panel in a vacuum firing furnace, vacuumizing to 1.5 to 1.8 *10<-2>Pa under the furnace temperature of 100 to 200 DEG C, and adopting the multi-arc ion plating technique to deposit a layer of pure metal base on surface of plating piece, wherein the metal material is chromium, B) preparing a CrN layer on the metal base, coating film for 10 to 20 min, keeping vacuum degree being 2 to 3 *10<-1>Pa, and depositing a layer of CrN about 0.2 to 0.3 microns on the surface of 430 stainless steel, C) passivating and cooling after finishing the process of coating film. The invention can promote the antiseptic property of surface of 430 stainless steel panel and is environment-friendly and energy saving.
Description
technical field [0001] The invention relates to a manufacturing process for improving the anticorrosion performance of stainless steel plates. Background technique [0002] 430 stainless steel is a typical representative of the 4 series stainless steel. The thermal conductivity of 430 stainless steel is better than that of austenite, the coefficient of thermal expansion is smaller than that of austenite, and it is resistant to thermal fatigue. It is added with stabilizing element titanium and has good mechanical properties in welded joints. It is becoming more and more popular. It is widely used in various industries, such as architectural decoration, fuel burner parts, household appliances, and home appliance parts. Compared with 304 stainless steel, 430 stainless steel has significant cost and price advantages, but because its corrosion resistance in the natural environment is far inferior to 304 stainless steel, its application in some high-demand fields is limited.
