Manganese phosphating coated steel wire rope is a patented product that has just been listed in batches in recent two years. At present, several enterprises have obtained patent licenses for legal production. The price of phosphating coated wire rope is higher than that of smooth wire rope, but the unit use cost is lower than that of smooth wire rope. At present, the test data prove that the fatigue life of phosphating coated steel wire rope is three times that of smooth steel wire rope, and the service life of steel wire rope is proportional to the fatigue life. According to the approximate price of wire rope market, the price of manganese phosphating coated wire rope is about 1.4- 1.6 times that of smooth wire rope, and the service life is much longer than the price increase. Therefore, the daily average cost of phosphating coated steel wire rope is only 40-55% of that of smooth steel wire rope.
Users who have used wire ropes know that wear and corrosion are the main causes of wire rope damage. Phosphating coated steel wire rope produced by patented technology gives priority to manganese series or zinc-manganese series phosphating. Compared with the production process of smooth steel wire rope, only the final wear-resistant phosphating process is added, which greatly improves the wear resistance and corrosion resistance of steel wire rope. The phosphatized steel wire rope is directly cold-drawn and twisted. At present, the fatigue test data show that the fatigue life of phosphating coated steel wire rope is about three times that of smooth steel wire rope with the same structure (under comparable conditions in the laboratory), and it is still possible to greatly improve with the research of wear-resistant phosphating formula. Manganese phosphating is wear-resistant phosphating, which can solve the wear problem of steel wire rope in use. Smooth steel wire rope was eliminated because phosphating coated steel wire rope is in short supply, and there is demand at present, which is for reference only.
