Standard for hardness requirements of galvanized iron wire
Galvanized iron wire is processed from high-quality low-carbon steel wire rods, which are drawn, pickled, rust removed, high-temperature annealed, and hot-dip galvanized. Processed through cooling and other processes. Galvanized iron wire is further divided into hot dip galvanized iron wire and cold dip galvanized iron wire (electro galvanized iron wire). Galvanized iron wire has the characteristics of strong toughness, high elasticity, and strong corrosion resistance, and is widely used in industrial production and daily life. The service life of an item is directly related to its maintenance and upkeep. When using galvanized iron wire, the first thing to consider is the hardness, and only the hardness of the galvanized iron wire meets the required standard. So, what are the standards for the hardness requirements of galvanized iron wire?
The hardness standard of galvanized iron wire is an important performance indicator. But for the hardness of metal materials, the resistance of the material to plastic deformation, scratches, wear, or cutting caused by indentation. In the debugging of the galvanizing distance of galvanized iron wire, keep the original vehicle speed unchanged, and estimate the galvanizing distance based on the galvanizing time and the diameter of the steel wire. By adjusting the galvanizing distance of galvanized iron wire, the galvanizing time of various specifications of galvanized iron wire is shortened by an average of 5 seconds compared to before debugging, thus reducing the zinc consumption. The zinc consumption per ton of galvanized iron wire is reduced from the original 61kg to 59.4kg.
Galvanized iron wire is dipped and plated in a heated molten zinc solution, with fast production speed and uneven but thick coating. The minimum thickness allowed by importers and customers is 45 microns, which can reach over 300 microns. The color is darker, consumes more zinc metal, forms an infiltration layer with the base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environments. The production of galvanized wire must meet the standards.
