Manganese phosphating coated wire rope is the most advanced technology in the field of wire rope in the world, and the hot spot of wire rope industry is phosphating coated wire rope. Many enterprises have obtained the patent authorization of legal production, and the papers on the production and use of phosphating coated steel wire rope are hot spots, as well as the papers on the simulation research and fatigue life test of phosphating coated steel wire rope, which were first published in journals and magazines.
The longest fatigue life is the main basis for judging whether the wire rope manufacturing technology is advanced or not. The fatigue life of wire rope can be verified and compared by fatigue test. A structural steel wire rope, such as 8 * 19s+NF- 12mm steel wire rope, was purchased from several manufacturers and tested on the same fatigue testing machine until the first strand broke. The wire rope with the longest fatigue life is the wire rope with the longest service life, and the comprehensive quality of the wire rope can be tested through fatigue test. The service life of wire rope is proportional to the fatigue life.
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. for reference only
