Steel wire rope is composed of steel wire, rope core and grease, and the steel wire will be stretched and deformed under the action of tensile stress, which is determined by the properties of steel. When the deformation of two steel wires in contact with each other is not synchronous, there will be relative sliding between the two steel wires, which will produce friction on the surface of the steel wire and lead to the surface wear of the steel wire.
To solve the problem of wire rope wear, oiling and supplementary lubrication can play a certain role, and phosphating coated wire rope is the most effective method to prevent wire rope wear at present. The surface of steel gear of automobile gearbox is phosphatized by manganese series, which improves the wear resistance and corrosion resistance of the gear surface and ensures the gear to work normally for more than ten years without damage.
The main reason of wire rope failure is fretting fatigue. At present, the first preventive measure against fretting fatigue in the field of wire rope in the world is the phosphating coated wire rope produced by patented technology, which is the most advanced technology in the field of wire rope in the world. After manganese phosphating or zinc-manganese treatment, the surface wear resistance and corrosion resistance of wire rope are improved in an all-round way, and the fatigue life of wire rope is greatly improved because it is not easy to wear and corrosion. The fatigue life is 3-4 times that of smooth steel wire rope with the same structure (under comparable conditions in laboratory), which can be verified by fatigue test. If you have your own fatigue testing machine, you can do a comparative test yourself. This test result is the most credible. The service life of wire rope is proportional to the fatigue life, and the service life is also extended in the same proportion. According to the approximate price of wire rope market, the price of manganese phosphating coated wire rope is higher than that of smooth wire rope. However, the extension of service life is much higher than the price increase, so the daily average service cost of phosphating coated steel wire rope is only about 30% of that of smooth steel wire rope, with lower service cost and higher cost performance. .
Phosphate coated steel wire rope has longer service life, lower use cost and better stability than smooth steel wire rope. Phosphating steel wire rope is produced by patented technology. Because it is in short supply, it is difficult to buy it at present, so it is necessary to ask the wire rope manufacturer more. Please note that the name of wire rope, such as phosphating wire rope, must be indicated on the purchase invoice to prevent illegal enterprises from infringing their legitimate rights and interests. In addition, patented products are generally painted with patent numbers on the outer packaging of wire ropes. The warranty shall include the main technical indicators such as the type and weight of phosphating film (phosphating film has a great influence on the service life of wire rope, such as wear resistance and corrosion resistance, etc.) for reference only.
