The steel wire rope is subjected to alternating stress during use. Micro-wear first occurs and fatigue cracks gradually develop. Cracks propagate, causing wire breakage and wire breakage. The wear reaches a certain level. The wire rope is scrapped. The steel wire rope has a short service life. To be precise, the service life is short, which ultimately leads to a short service life. The quality of the original wire rope is low, and the service life must meet the requirements. You must buy shoddy and inferior wire ropes. The selection of the wire rope must be correct. The usage of the wire rope must be lubricated and maintained. Manganese phosphating coated wire ropes must be advanced in the field of steel wire ropes. The fatigue life of the smooth wire rope is tripled. Crane users need high-quality wire ropes. It should have a long service life and highly stable quality. The main cause of failure of steel wire ropes is micro-fatigue, which is caused by the use of steel wire ropes in gas environments. Micro-fatigue is currently the first micro-fatigue in the world's steel wire rope field. Preventive and control measures have been taken. Patented technology produces phosphating-coated steel wire ropes. Steel wires are manganese-based phosphated or zinc-manganese. The surface wear resistance and corrosion resistance of the treated steel wire are comprehensively improved. It is easy to wear and corrode, which greatly increases the fatigue life of the steel wire rope. The fatigue life of the smooth steel wire rope with the same structure is three to four times (laboratory conditions). Verified by fatigue testing, self-fatigue testing machine Do a comparison test to find out the relationship between the service life and fatigue life of the steel wire rope. The fatigue life is the same as the service life. According to the current price of the steel wire rope market, the price of the manganese phosphating coated steel wire rope is about 4 times the service life of the smooth steel wire rope. The extension rate is much higher than the price increase. The usage cost of all phosphate-coated steel wire ropes is only 30-45% for smooth steel wire ropes. The usage cost of phosphate-coated steel wire ropes is lower and more cost-effective. The phosphate-coated steel wire ropes have a lower usage cost than smooth steel wire ropes and are more stable. The production and supply of patented technology for phosphate-coated steel wire ropes are better, and it is currently difficult to buy. You need to inquire with several steel wire rope manufacturers. Please note that the purchase invoice must indicate the name of the steel wire rope. Phosphate-coated steel wire ropes prevent companies from infringing on their own rights and interests. In addition, patented products are similar to steel wire ropes. The outer packaging patent number should be spray-marked with a warranty and the main technical indicators should be the type of phosphate film and weight (the weight of the phosphate film, abrasion resistance, corrosion resistance and other important influences on the service life of the wire rope)
