It is imperative for manganese phosphating steel wire rope to completely replace smooth steel wire rope for the following reasons:
First of all, the service life of wire rope is proportional to the fatigue life, and the longer the fatigue life, the longer the service life. At present, the fatigue test has confirmed that the fatigue life of manganese phosphating coated steel wire rope is 3-4 times that of smooth steel wire rope with the same structure. If you have a fatigue testing machine, please do the fatigue life comparison verification test yourself.
Users who have used wire ropes know that after using wire ropes, the diameter of wire ropes will become smaller due to wear and tear, and corrosion and broken wires will gradually appear. These conditions show that wear, corrosion and fatigue wire breakage are the main causes of wire rope failure.
Manganese phosphating has been used in machinery industry for decades. The surface of steel gear of automobile gearbox is treated with manganese phosphating film, which can ensure that the gear can be used normally for more than ten years without wear. The surfaces of worm gear and piston ring are treated by manganese phosphating coating, which can improve the wear resistance and corrosion resistance of steel surface, thus effectively inhibiting the occurrence of wear and corrosion and further prolonging the service life.
The purpose of manganese phosphating coated wire rope is to improve the wear resistance and corrosion resistance of the wire rope surface, so as to achieve the purpose of improving the service life. It is true that manganese phosphating film can improve the service life of steel wire rope, with longer service life, lower use cost and higher safety and stability. To be sure, it will completely replace the smooth steel wire rope, and all kinds of smooth steel wire rope will soon withdraw from the market.
The patent technology of phosphating coated wire rope is the most advanced technology in the field of wire rope in the world at present. The fatigue life of manganese phosphating coated steel wire rope is 3-4 times that of smooth steel wire rope with the same structure, which can be verified and compared through fatigue test. At present, there is no wire rope with the same structure whose fatigue life can exceed that of phosphating coated wire rope, so the patented technology of phosphating coated wire rope is the most advanced technology, at least in the field of wire rope in the world at present. Manganese phosphating film can improve the wear resistance and corrosion resistance of steel gear surface of automobile gearbox, and prolong the service life of steel wire rope by using this principle. Phosphating coated steel wire rope has longer service life, lower unit use cost, higher stability and reliability, and it is inevitable to win the trust of wire rope users.
The fatigue test shows that the fatigue life of manganese phosphating coated elevator wire rope is the longest among the same structure wires. This technology is an invention patent of China, and many enterprises purchase patents to authorize mass production of manganese phosphating coated steel wire ropes. The service life of manganese phosphating coated steel wire rope is very long, and the daily average service cost is only about 30% of that of smooth steel wire rope. It is an upgraded product of various smooth steel wire ropes.
