How To Distinguish Between Smooth Steel Wire Rope And Galvanized Steel Wire Rope

2002/9/14      view:

Smooth steel wire rope is made of uncoated steel wire twisting, in order to rust, twist the completion of the wire rope at the same time to do soaked oil treatment, this kind of wire rope as a whole oil. Inside and outside are. Wiping the surface of the metal into the metal can not cover the presence of rust. Exposure to oil-free place to see yellow rust.

Galvanized steel wire rope is made of zinc wire has been twisted, because the surface has been galvanized, twisted after the completion of the general is no longer soaked in oil treatment, the overall lack of oil wire rope, if only concentrated in the core. Metallic white on the surface of zinc. Such as the new lead color. Stock long time as old lead wire color, no rusty yellow to see.

 It can be used in the fields of high-rise buildings, transportation and transportation, traction, strapping and other fields for shipping, offshore oil exploration, aircraft handling and marine fishing. The same time as the above-

Galvanized rope rope core used in the past commonly used sisal and jute manufacturing, but because of these materials at work easy to absorb acid, alkali, seawater and other corrosive substances, resulting in the early corrosion of the inner wire wire, has been switched to polypropylene as a core. The same time as the above-

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 The thickness can be divided into 3 galvanized steel wire rope group: the amount of zinc on the thin coating group is 15 ~ 135g / m2, for mild corrosion conditions; in the coating group zinc content of 60 ~ 200g / m2, for medium corrosion conditions; The amount of zinc on the galvanized group is 75 to 260 g / m2 for severe 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. The same time as the above-

Galvanized steel wire with multi-line continuous hot-dip plating and plating two methods. The same time as the above-

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 practical zinc content of zinc can reach 1200g / m2. , The general zinc plating layer of zinc can reach 750g / m2. While the highest value of zinc on hot zinc plating, but also 593g / m2.

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. The same time as the above-
