Galvanizing is the technique of dipping iron or steel products into molten zinc for coating. The purpose of galvanizing is to increase the corrosion resistance of metal products, extend the service life, and make its surface more beautiful. In the galvanizing process, wire drawing technology is an important process, which can ensure the smoothness of the product surface.
Galvanized wire drawing technology is to make the metal product slender and reduce the diameter by drawing, thereby increasing the hardness and strength of the product, and improving the smoothness of the surface.
Here are some of the key steps and points to ensure product surface smoothness:
1. Material selection: In view of the purpose of galvanizing is to improve the corrosion resistance of metal products, the selected material must have good corrosion resistance. In general, carbon steel is one of the commonly used materials, and its corrosion resistance is strong.
2. Surface treatment: Before wire drawing, the surface of metal products should be cleaned and degreased to remove surface impurities and dirt. This ensures that the surface of the product is smoother after drawing.
3. Adjust the drawing process parameters: the drawing process parameters include drawing speed, drawing pressure, cooling method, etc. By adjusting these parameters, the shape and size of metal products can be changed, and the degree of metal deformation during wire drawing can be controlled. Reasonable selection and adjustment of these parameters can ensure the smoothness of the product surface.
4. Use the right lubricant: In the drawing process, the choice of lubricant plays a key role. Lubricants can reduce friction and reduce surface roughness, thus ensuring the smoothness of the product surface. Commonly used lubricants are tempered oil, vulcanized oil and so on.
5. Strengthen equipment maintenance and maintenance: The maintenance and maintenance of wire drawing equipment is important to ensure the smoothness of the product surface. Regular cleaning of the equipment, replacement of worn parts, and maintenance of the normal operation of the equipment can reduce the generation of bad products and improve the smoothness of the product surface.
6. Quality inspection: Galvanized products need to be inspected after wire drawing to ensure the smoothness of their surface. Common detection methods include visual inspection, touch and microscope. Through detection, the defects existing on the surface can be found and treated in time to improve the quality of the product and the smoothness of the surface.
