When purchasing large rolls of galvanized wire, we must first look at the hardness of galvanized wire, only after the hardness reaches the standard can be used. The hardness standard of galvanized wire is a very important performance index and an economical test method. However, for the hardness of metal materials, there is no unified and clear definition including all test methods at home and abroad. Generally speaking, the hardness of a metal is often considered to be the resistance of a material to plastic deformation, scratches, wear or cutting.
In the adjustment of zinc dip distance of galvanized wire, keep the original speed unchanged, and estimate the zinc dip distance according to the time of zinc dip and the diameter of steel wire. By adjusting the zinc immersion distance, the zinc immersion time of various specifications of steel wire is shortened by 5s on average than before debugging, so that the zinc consumption is reduced, and the zinc consumption per ton of steel wire is reduced from the original 61kg to 59.4kg. Galvanized wire is dipped in the heated melting zinc solution, the production speed is fast, the coating is thick but not uniform, the market allows the thickness of 45 microns, up to 300 microns or more.
The color is dark, the consumption of zinc metal is more, the infiltration layer is formed with the base metal, the corrosion resistance is good, and the hot dip galvanizing can be maintained for decades in the outdoor environment. Galvanized wire according to the production technology can be divided into: hot galvanized iron wire, electroplating iron wire hot plating: 8# — 36#(3.8mm,0.19mm) electroplating: 8# — 38#(3.8mm-0.15mm) Production technology: through the excellent low carbon steel wire drawing molding, pickling rust, high temperature annealing, hot galvanized, cooling and other 5 processes refined.
Galvanized wire characteristics: good resistance and elasticity, strong corrosion resistance. Used for communication devices, medical devices and braid nets, brushes, steel cables, filters, high-pressure pipes, construction, technical products and other professional electrogalvanized wire: is a low carbon steel as the core wire, through wire drawing, electrogalvanized processing of metal composite materials. Hot-dip galvanized wire: This product uses excellent carbon structural steel, by drawing, hot-dip galvanized processing.
Widely used in the manufacture of wire mesh, highway barrier and construction projects. With thick coating, corrosion resistance construction binding with iron wire is 22#(0.71mm), low price, its characteristics of good flexibility, not easy to break, is one of the ideal binding wire construction industry, the main choice of low zinc cold plating treatment of iron wire. The first choice of low zinc cold plating treatment of wire.
