What Are The Uses Of Galvanized Steel Wire Ropes?

- Sep 21, 2017 -

The utility model can be used in the fields of advanced building, vehicle and ship bundling, traction and banding, etc., and is used for shipping, ocean petroleum exploration, aircraft manipulation and ocean fishing, etc..

Rope core galvanized steel wire rope used for sisal and jute manufacturing, but because these materials can work in the adsorption of acid and alkali, seawater corrosion, corrosion caused by inner wire early broken wire, has been used for polypropylene rope core.

Galvanized steel wire rope twisting and round strand wire rope, wire rope but according to working conditions, the thickness of zinc coating on wire materials have different requirements: 0.2 ~ 5.0mm in diameter and I characteristics of galvanized steel wire rope, the thickness of the coating can be divided into 3 groups: galvanized steel wire rope thin coating group the amount of zinc is 15 ~ 135g/m2, for mild corrosion conditions; in coating group the amount of zinc is 60 ~ 200g/m2, for moderate corrosion condition; thick galvanized group the amount of zinc is 75 ~ 260g/m2, for serious corrosion conditions. In order to ensure the quality of the wire rope, the surface of the galvanized steel wire should be smooth, complete, uniform and firm. When the galvanized steel wire is spirally wound on a mandrel 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 zinc coating shall also be examined accordingly.

There are two methods of wire continuous galvanizing and electroplating.

Electro galvanized (see steel wire zinc plating) is obtained by means of external power supply by electrodeposition. The coating obtained is composed of fine pure zinc grains. Hot dip galvanized (see wire galvanized) by heat diffusion physical form coating, first formed Fe Zn compounds have been generated in a pure zinc layer surface of zinc compounds. Theoretically, the zinc layer with arbitrary thickness can be obtained by galvanizing. At present, the amount of zinc in practical zinc plating can reach 1200g/m2. In general, the amount of zinc on the electroplated zinc layer is up to 750g/m2. The maximum amount of zinc on hot galvanizing is also 593g/m2.

Hot galvanizing will reduce the mechanical properties of steel wire, requiring high strength and high corrosion resistance galvanized steel wire, galvanized wire twisting is used.
