The main material of wire rope is conductive steel wire, and lightning strikes release the life of wire rope workers. Pay attention to safety, for reference only.

The output of steel wire rope is10.8 million tons, ranking first in the world in phosphating coated steel wire rope. The revolutionary innovative technology in the field of wire rope in the world has greatly improved its service life (fatigue life). Smooth steel wire rope has been completely eliminated and completely replaced by phosphating coated steel wire rope;

1. Phosphated steel wire rope (patent) After phosphating with manganese or zinc-manganese series, the wear resistance and corrosion resistance of steel wire surface have all-round leap GB/T11376-1997 metal phosphate conversion film is the standard for wear resistance. The antirust function is introduced in detail. Oil permeates into the pores of phosphating film and has excellent antifriction effect. Smooth steel wire rope is upgraded to galvanized steel wire rope with thin zinc layer. The fatigue life of smooth steel wire rope is about 3 ~ 4 times. Fatigue life is shorter than that of fatigue test. With the in-depth study of wear-resistant phosphating solution, the service life has been improved. The phosphating film is 3-60 g/m2. Steel wire phosphating is used for drawing, and steel wire rope is directly twisted.

Note: Zinc phosphating for drawability is confused with manganese phosphating or zinc-manganese phosphating for rope steel wire. This technology is suitable for producing elevator wire rope, important wire rope, mine wire rope, anti-rotation wire rope, wire rope for oil production, wire rope for pile driver and so on. Lower service life and better stability.

2. Galvanized steel wire rope includes two kinds of vertical galvanized steel wire. The thicker the zinc layer, the stronger the corrosion resistance. The thinner the galvanized steel wire rope used. Due to the corrosion resistance of phosphating film, manganese phosphating film steel wire rope replaced some thin galvanized steel wire rope varieties. The corrosion resistance of hot dip galvanized-phosphating double-coated steel wire rope is improved in humid and high temperature air environment.

3. Rusted steel wire rope 304 or 3 16 is twisted with rusty steel wire. The corrosion resistance of rusty steel wire rope is higher than that of hot-dip galvanized carbon steel wire rope. The expensive rusty steel wire is coated with manganese phosphating (the phosphating of rusty steel wire requires special phosphating), and the service life is also prolonged.

4. Plastic coated steel wire rope or strand rope is coated with polyethylene and polypropylene.

5. Smooth steel wire rope was put into production in English 1834, and Jindi Steel Wire Rope Factory was put into production (went bankrupt in 2005). With a large number of phosphating coated wire ropes entering the market, phosphating coated wire ropes have been completely eliminated.

6. Approval process for the formulation of relevant standards for mooring wire ropes in offshore engineering.

7. Wire rope

Manganese phosphating coated steel wire rope optimizes gas environment, hot dip galvanized-phosphating double coated steel wire rope optimizes corrosion environment, and marine steel wire rope optimizes seawater environment, which has longer service life and lower cost.
