What are the characteristics of different galvanized steel wire ropes? [answered]

Steel wire rope is widely used in some daily drawing work. In order to enhance the anti-corrosion ability of steel wire rope, some treatment processes are usually adopted for steel wire rope. The common steel wire rope treatment process is galvanizing. In the past, the rope core of galvanized steel wire rope was usually made of sisal and jute. However, these materials are easy to absorb acid, alkali, seawater and other corrosive substances during work, resulting in early corrosion and wire breakage of the inner steel wire. Polypropylene has been used as the rope core.

Galvanized steel wire rope is mainly divided into two categories: steel wire rope of cold galvanizing process and steel wire rope of hot galvanizing process. Most of the users choose hot-dip galvanized steel wire rope. Galvanized steel wire rope is used for traction, control and operation, as well as rickshaw, electric vehicle, equipment, brake line, speed change line and lighting hanging line. The products are mainly used for fitness equipment, activity setting equipment, medical setting equipment, activity nets, beauty setting equipment, safe rigging operation insurance. The product has the advantages of high tensile strength, wear resistance, corrosion resistance, beautiful appearance and so on.

There is an essential difference between hot-dip galvanizing and cold galvanizing in terms of process. Hot galvanizing relies on physical thermal diffusion to form coatings. First, iron zinc compounds are formed, and then pure zinc layers are formed on the surface of iron zinc compounds. However, the maximum amount of zinc on hot-dip galvanizing is only 593g/m2. Hot dip galvanizing will reduce the mechanical properties of steel wire. Steel wire ropes with high strength and corrosion resistance are usually twisted with electro galvanized steel wire. Hot dip galvanizing is zinc plating 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 with hot galvanizing process has super high cost performance. The steel wire of the steel wire rope of the hot 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. The maximum zinc content on the steel wire rope of hot galvanizing process is only 593g/m2. Hot dip galvanizing is zinc plating in a molten zinc bath at 450-480 degrees. In order to ensure the quality of the steel wire rope, the galvanized surface of the steel wire shall be smooth, complete, uniform and firm. When the galvanized steel wire is spirally wound on a core rod with a diameter of 5 or 10 times the diameter of the steel wire, the zinc layer shall not fall off or crack. The corrosion resistance of the zinc coating shall also be tested accordingly.
