What are the characteristics of different galvanized steel wire ropes
2023-04-17
Wire ropes are commonly used in some daily drawing work. When used, in order to enhance the corrosion resistance of the wire rope, some treatment processes are generally adopted for the wire rope. The common wire rope treatment process is galvanizing. In the past, the core of galvanized steel wire rope was usually made of sisal and jute, but because these materials are easy to absorb acid, alkali, sea water and other corrosive substances during work, the inner steel wire rusts and breaks in the early stage. 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 are steel wire ropes with hot-dip galvanizing technology. The galvanized steel wire rope is used for traction, manipulation, manipulation and rickshaws, electric vehicles, and brake lines, transmission lines, and lighting suspension lines. The products are mainly used for fitness equipment, activity equipment, medical equipment, activity nets, beauty equipment, safety rigging operation insurance. The product has the advantages of high tensile strength, wear resistance, corrosion resistance, and beautiful appearance. Hot-dip galvanizing and cold-dip galvanizing have this essential difference in the process. Hot-dip galvanizing relies on physical thermal diffusion to form a coating. First, iron-zinc compounds are formed, and then a pure zinc layer is formed on the surface of the iron-zinc compounds. The highest value of zinc on hot-dip galvanizing is only 593g/m2. Hot-dip galvanizing will reduce the mechanical properties of the steel wire, and the steel wire rope that requires high strength and high corrosion resistance of the galvanized process is mostly twisted by electro-galvanized steel wire. 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 hot-dip galvanized steel wire rope relies on physical thermal diffusion to form a coating. 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 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 steel wire galvanized layer should 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 should not fall off or crack. Corresponding inspection should also be done for the corrosion resistance of the galvanized layer. |
