The commonly used steel wire ropes are phosphating coated steel wire ropes, galvanized steel wire ropes, stainless steel wire ropes or plastic coated steel wire ropes, which are used in atmospheric environment. The manganese phosphating coated steel wire ropes produced by patented technology have the longest service life, and the fatigue life of phosphating coated steel wire ropes is 3-4 times that of smooth steel wire ropes. In heavy corrosion environment, hot dip galvanized-phosphating double-coated steel wire ropes with outstanding corrosion resistance are preferred, and smooth steel wire ropes are being eliminated for reference only.
Manganese phosphating belongs to wear-resistant and corrosion-resistant phosphating. The steel gear of automobile gearbox is treated with manganese phosphating, which can ensure that the automobile gear will not be damaged for more than ten years. The phosphating coated steel wire rope produced by China patent technology gives priority to manganese series or zinc-manganese series phosphating. Compared with the production process of smooth steel wire rope, it only adds the last abrasion-resistant phosphating process, which greatly improves the wear resistance and corrosion resistance of steel wire rope, and uses phosphating steel wire to directly twist steel wire rope. At present, the fatigue test data show that the fatigue life of phosphating coated steel wire rope is about 3-4 times that of domestic smooth steel wire rope with the same structure, and 2-3 times that of imported smooth steel wire rope. With the study of wear-resistant phosphating formula, it is possible to greatly improve it, and it is the most advanced technology in the field of steel wire rope in the world. Manganese phosphating is wear-resistant phosphating, which can solve the wear problem of steel wire rope in use. Smooth steel wire rope is being eliminated, because the demand for phosphating coated steel wire rope is in short supply, and it is in demand at present, so it is necessary to ask more enterprises.
The price of phosphating coated steel wire rope is higher than that of smooth steel wire rope, but the unit use cost is lower than that of smooth steel wire rope. The current test data prove that the fatigue life of phosphating coated steel wire rope is 3-4 times that of smooth steel wire rope, and the service life of steel wire rope is in direct proportion. According to the approximate price of steel wire rope market, although the price of manganese phosphating coated steel wire rope is higher than that of smooth steel wire rope, the service life extension is much higher than the price increase. Therefore, the daily average service cost of phosphating coated steel wire rope is only about 3% of that of smooth steel wire rope, with longer service life, lower unit service cost and higher stability, safety and cost performance ratio during use.
