What Is The Use Of Galvanized Steel Wire Rope?
Our company is a specialized production of steel wire business, we uphold the concept of quality priority in the industry step by step expansion, the company introduced advanced machinery and equipment and first-class production line, if you want to buy our products, Wrong, the following simple to introduce you to the characteristics of my company's products, I hope you can like.
The galvanized steel wire rope produced by our company can be used in the fields of advanced building, ship bundle, traction, strapping and other fields for shipping, offshore oil exploration, aircraft handling and marine fishing, trawl, fixed net, roll net and other fisheries.
My company galvanized steel cord rope used in the past commonly used sisal and jute manufacturing, but because of these materials at work easy to absorb acid, alkali, sea water and other corrosive substances, resulting in the early corrosion of the inner wire wire, has switched to polypropylene for the rope core.
Galvanized steel wire rope twist and ordinary round wire rope the same, but according to the use of wire rope working conditions, the thickness of the raw material steel zinc layer has different requirements: diameter 0.2 ~ 5.0mm special number and I galvanized steel wire rope, coating Thickness can be divided into three groups: the amount of zinc on the thin coating group is 15 ~ 135g / m2, for mild corrosion conditions; the amount of zinc on the coating group is 60 ~ 200g / m2 for medium corrosion conditions; The amount of zinc on the 75 ~ 260g / m2, for serious corrosion conditions.
In order to ensure the quality of wire rope, steel galvanized layer surface should be smooth, complete, uniform and solid. When the galvanized steel wire is spirally wound on a mandrel with a diameter of 5 times or 10 times the diameter of the wire, the zinc layer should not fall off or crack. The corrosion resistance of the galvanized layer should also be checked accordingly.
Galvanized steel wire rope with multi-line continuous hot-dip plating and plating two methods.
Electroplating of zinc (see galvanized steel wire) is through the external power supply, electrodeposition way to obtain the coating, the coating is obtained by the fine composition of pure zinc particles. Hot-dip galvanized (see hot-dip galvanized steel wire) is formed by the physical diffusion of heat to form a coating, the first formation of iron-zinc compounds, one by one in the iron-zinc compound surface pure zinc layer. In theory, galvanized zinc can be obtained in any thickness. At present, the amount of zinc on the practical zinc plating can reach 1200g / m2.
General zinc plating on the amount of zinc can also reach 750g / m2. While the highest value of zinc on hot zinc plating, but also 593g / m2. The Hot galvanized will reduce the mechanical properties of steel wire, requiring high strength and high corrosion resistance of galvanized steel wire rope, and more use of galvanized steel wire twisting.
