Hot-dip galvanizing and cold-dip galvanizing have this essential difference in process. Hot-dip galvanizing relies on physical thermal diffusion to form a coating. First, an iron-zinc compound is formed, and a pure zinc layer is successively formed on the surface of the iron-zinc compound. The highest zinc content on hot-dip galvanizing is only 593g/m2. Hot-dip galvanizing will reduce the mechanical properties of steel wires, and steel wire ropes that require high strength and high corrosion resistance galvanized processes are mostly twisted with electro-galvanized steel wires. Hot-dip galvanizing is zinc plated in a molten zinc bath at 450-480 degrees.
Hot-dip galvanized steel wire rope is a market trend and will become the first choice for users of galvanized steel wire rope. Because the steel wire rope of the hot-dip galvanizing process has a super high cost performance. The steel wire of the steel wire rope in the hot-dip galvanizing process forms a coating by physical thermal diffusion. First, an iron-zinc compound is formed, and then a pure zinc layer is formed on the surface of the iron-zinc compound on the surface of the galvanized steel wire. And the highest value of zinc on the steel wire rope of the hot-dip galvanizing process is only 593g/m2. Hot-dip galvanizing is zinc plated in a molten zinc bath at 450-480 degrees. In order to ensure the quality of the steel wire rope, the surface of the galvanized layer of the steel wire should be smooth, complete, uniform and firm. When the galvanized steel wire is helically wound on the core rod whose diameter is 5 or 10 times the diameter of the steel wire, the zinc layer should not fall off or crack. The corrosion resistance of the galvanized layer should also be tested accordingly.
