The working principle of stainless steel processing mainly includes the following aspects:
Surface treatment process: There are many surface treatment processes for stainless steel, the most common ones are mirror treatment, wire drawing and etching.
Mirror treatment: Through polishing and grinding equipment, high-quality oilstone, diamond grinding paste and sandpaper of different brands are used to obtain a mirror-like bright surface after rough grinding, medium grinding and fine grinding. The professional name of the mirror is 8K, and its grades can be divided into 6K, 8K, fine grinding 8K, and super fine grinding 8K. The difference lies in the brightness of the surface and the control of the texture.
Wire drawing (frosting): Use a high-speed rotating sand belt to grind the surface of the stainless steel plate to form regular stripes. The types of wire drawing include ordinary sand, snowflake sand, straight wire drawing, etc. The larger the value of the sand belt, the finer the sand grain. The specifications of wire drawing are 0.4-3.0mm thickness and 1000MM-1500MM width. The conventional thickness and width can be adjusted according to needs. Etching treatment: Use molds and potions to corrode stainless steel plates to obtain the desired pattern effect. Etching is divided into photosensitive etching, silk screen etching, titanium stripping, etc. Cold drawing process: During the cold drawing process, the metal will undergo plastic deformation, causing multiple slip systems inside the crystal to start. Dislocation movements intercept each other, and dislocations are pinned, causing dislocation accumulation, and the dislocation density in the crystal increases significantly. As plastic deformation further occurs, the stress increases and is sufficient to cause the pinned dislocations to start moving, and the hardness and strength of the metal material are improved. Processing principle of stainless steel sieve plates: Stainless steel sieve plates are used in many industries such as metallurgy, nonferrous metals, gold, coal, chemicals, building materials, and hydropower engineering. Equipment and technology need to be continuously optimized during the processing process to ensure the accuracy and quality of the product. The punching sieve plate machine is used for plane incision cutting of medium and small sections. The material is punched halfway through the flat die and pressed back into the plate to ensure the accuracy and effect of the punching.
