Difference between broken wire and broken strand of steel wire rope

In the process of use, the steel wire rope is first worn, then broken and finally scrapped, which is the failure process of the steel wire rope. Wear and broken wires are the main basis for judging whether wire ropes are scrapped or not. It is recommended to use manganese phosphating coated steel wire rope. Phosphating coating can improve the wear resistance and corrosion resistance of steel wire surface, thus greatly improving the service life.

Please refer to gb/t29086-20 12 wire rope.

National standards for inspection and scrapping. It is suggested to use manganese phosphating coated steel wire rope, whose service life far exceeds that of smooth steel wire rope.

Smooth wire rope:

Smooth steel wire → twisting → winding.

Phosphating coated wire rope:

Smooth steel wire → manganese series or zinc-manganese series phosphating → twisting → winding.

The above is the production process of phosphating coated steel wire rope and smooth steel wire rope. It can be seen that phosphating coated steel wire rope has one more phosphating process of manganese or zinc-manganese system than smooth steel wire rope.

The patent technology of phosphating coated wire rope is the most advanced technology in the field of wire rope in the world at present. The fatigue life of manganese phosphating coated steel wire rope is 3-4 times that of smooth steel wire rope with the same structure, which can be verified and compared through fatigue test. At present, there is no wire rope with the same structure whose fatigue life can exceed that of phosphating coated wire rope, so the patented technology of phosphating coated wire rope is the most advanced technology, at least in the field of wire rope in the world at present. Manganese phosphating film can improve the wear resistance and corrosion resistance of steel gear surface of automobile gearbox, and prolong the service life of steel wire rope by using this principle.

Phosphating steel wire rope has longer service life, lower unit use cost and higher cost performance. It is an upgraded product of smooth wire rope, and all kinds of smooth wire ropes are being eliminated. For reference only.
