In the purchase of large rolls of galvanized wire, see the hardness of galvanized wire first, only after the hardness reaches the standard can be used. The hardness standard of large roll galvanized wire is a very important performance index and an economic test method. But 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 AS THE RESISTANCE OF a MATERIAL TO COMPRESSION PLASTIC deformation, scratches, wear, or cutting. In the adjustment of zinc dip distance of galvanized wire, keep the original speed unchanged, according to the time of zinc dip, wire diameter, and then estimate the zinc dip distance. By adjusting the zinc dipping distance, the zinc dipping time of various specifications of steel wire is shortened by 5s on average compared with that before debugging, so that the zinc consumption is reduced, the zinc consumption per ton of steel wire is reduced from the original 61kg to 59.4kg.
Galvanized wire is immersed in heated molten zinc, the production speed is fast, the coating is thick but uneven. The thickness of 45 microns allowed by the market, the color is dark, the consumption of zinc metal is more, and the matrix metal is formed into an infiltration layer, and the corrosion resistance is good. The hot dip galvanizing can be maintained for decades in the outdoor environment.
