Phosphating coated steel wire rope is a patented technology in China. Its manufacturing process is phosphating steel wire, and then directly twisting steel wire rope with phosphating steel wire. The phosphatized steel wire rope is not cold drawn. The weight of phosphating film is 3-60g/m2, and manganese or zinc-manganese phosphating formula is preferred. These two phosphating films have excellent wear resistance and corrosion resistance, which can prevent the wear and corrosion of steel wire rope. Manganese phosphating on the surface of automobile gearbox steel gear has excellent wear resistance and corrosion resistance, which can ensure the gear to work normally for more than ten years. The principle of protecting and prolonging the service life of phosphating coated steel wire rope is also to improve wear resistance and corrosion resistance.
Taking the elevator wire rope with 8 * 19s hemp core and diameter of 13mm as an example, the fatigue test of elevator wire rope was carried out until it broke, and the fatigue life of phosphating coated elevator wire rope was 3-4 times that of smooth elevator wire rope with the same structure. For any industrial product, doubling the service life is a revolution in production technology, and phosphating coated steel wire rope is a revolutionary improvement. Its mechanical properties and other technical indicators are in line with the current national standards and industry standards, and can be used with confidence. for reference only
