Manganese phosphating belongs to wear-resistant and corrosion-resistant phosphating. After manganese phosphating treatment, the automobile gear box steel gear can be guaranteed not to be damaged for more than ten years. The phosphating coated steel wire rope produced by China patented technology is mainly phosphating with manganese series or zinc-manganese series. Compared with the production process of smooth steel wire rope, only the last wear-resistant phosphating process is added, which greatly improves the wear resistance and corrosion resistance of steel wire rope. Phosphated steel wire is used 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 research of wear-resistant phosphating formula, it may be greatly improved, and it is the most advanced technology in the field of 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 supply of phosphating coated steel wire rope is in short supply, and it is in short supply at present, so more enterprises need to be invited.
Although the price of phosphating coated steel wire rope is higher than that of smooth steel wire rope, 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, which is directly proportional to the service life of steel wire rope. According to the approximate price of wire rope market, although the price of manganese phosphating coated wire rope is higher than that of smooth wire rope, the service life extension is much higher than the price increase. Therefore, the average daily use cost of phosphating coated steel wire rope is only about 30% of that of smooth steel wire rope, with longer service life, lower unit use cost and higher stability, safety and cost performance in the use process.
