During the use of the smooth traction elevator wire rope, it is subjected to repeated effects of alternating stress, and the steel wire will undergo a certain degree of elastic elongation and deformation. When the deformation of the two steel wires in contact with each other is out of synchronization, the Relative sliding will occur between them, and fretting wear will occur on the surface of the steel wire. The wear causes the diameter of the wire rope to gradually decrease and the rope to become thinner. The worn place is the source of cracks that cause fatigue fracture. The faster the wear, the shorter the service life of the wire rope.
Currently, the most effective way to solve the problem of wire rope wear is manganese phosphating coating technology. Phosphated coated steel wire rope is a patented product. The surface of the rope-making steel wire is treated with manganese or zinc-manganese phosphating coating. The weight of the phosphate coating is generally greater than 15 grams/square meter. The phosphated steel wire is used to directly twist the steel wire rope (steel wire phosphated The drawing process will not be carried out in the future). Manganese or zinc-manganese phosphating are wear-resistant phosphating coatings, which can greatly improve the wear resistance and corrosion resistance of the steel wire surface. The surface of steel gears in automobile transmissions is treated with manganese-based phosphating coating, which can ensure that the gears can operate normally under high-speed and heavy-load conditions for more than ten years without damage. It can be seen that manganese-based phosphating is very effective in improving wear resistance. The manganese-based phosphating wear-resistant coating elevator wire rope also uses the above principle to extend its service life.
Manganese phosphating wear-resistant coating elevator wire rope fully complies with all technical indicators of current national standards and industry standards, and can be purchased and used with confidence. Manganese-based phosphating wear-resistant coated steel wire rope is currently the most advanced technology in the world's steel wire rope industry and the most wear-resistant steel wire rope. It is also an upgraded product of various smooth steel wire ropes, with longer service life and lower average daily use costs.
