1, galvanized hard wire standard and other galvanized wire or there is a difference, because the process of galvanized hard wire and other not quite the same. Galvanized wire hardness standard is one of the most important performance index, but also a very economic test method. However, for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad. In general, the hardness of a metal is often considered to be the resistance of the material to plastic deformation, scratches, wear, or cutting.
2. In the debugging of zinc dipping distance of galvanized wire, keep the original speed unchanged, and then estimate the zinc dipping distance according to the time of zinc dipping and the diameter of steel wire. By adjusting the zinc immersion distance, the zinc immersion time of steel wire of various specifications is shortened by 5s on average compared with that before debugging, so that the zinc consumption per ton of steel wire is reduced from 61kg to 59.4kg.
3, galvanized wire is in the heat of molten zinc dip plating, production speed, thick but uneven coating, the market allows the lowest thickness of 45 microns, up to 300 microns above. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment.
