Wear and corrosion are the causes of wire rope failure. Anti-corrosion and wear-resistant steel wire rope must have a long service life. Of course, the most wear-resistant and corrosion-resistant steel wire rope is manganese phosphating coated steel wire rope. 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.
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 30-45% of that of smooth steel wire rope, with longer service life, lower unit use cost and stability, safety and reassurance in the use process.
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.
Commonly used steel wire ropes include phosphating coated steel wire rope, galvanized steel wire rope, stainless steel wire rope or plastic coated steel wire rope, which are used in atmospheric environment. Manganese phosphating coated steel wire rope produced by patented technology has the longest service life, and hot dip galvanized-phosphating double coated steel wire rope is preferred in heavy corrosive environment.
To be sure, the advanced will eliminate the backward, as will any industrial product, such as mobile phones. Only the most advanced mobile phones can win customers, for reference only.
