Manganese phosphating coated steel wire rope is a patented technology, and many enterprises have obtained patent authorization for legal production.
The main raw materials for manufacturing manganese phosphating coated steel wire rope are high-quality carbon structural steel wire rod, sisal or jute rope core, grease and manganese phosphating solution. Wire rod is generally 60-70 steel, and elevator wire rope uses some 45 steel.
Crane users need high-quality wire ropes with long service life. Fretting fatigue is the main reason for the failure of steel wire ropes used in atmospheric environment. At present, the phosphating coated steel wire rope produced by patented technology is the first preventive measure against fretting fatigue in the world wire rope field and the most advanced technology in the world wire rope field. After manganese phosphating or zinc-manganese treatment, the wear resistance and corrosion resistance of steel wire surface are improved in an all-round way, and the fatigue life of steel wire rope is greatly improved because it is not easy to wear and corrosion. The fatigue life of smooth steel wire rope with the same structure is 3-4 times (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, and the service life of wire rope is directly proportional to the fatigue life.
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, and the extension of service life is much higher than the price increase. Therefore, the daily average use cost of phosphating coated steel wire rope is only about 30% of that of smooth steel wire rope, which is lower in use cost and higher in 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 in 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.
