Prolonging the service life is a goal universally pursued by all industrial products, and the same is certainly true for elevator wire ropes. It is inevitable that products with ultra-long service life will replace products with short service life. This is a concrete manifestation of technological progress.
Phosphating coated steel wire rope is a patented technology. It prefers manganese or zinc-manganese phosphating. Compared with the smooth steel wire rope production process, it only adds a wear-resistant phosphating treatment process for the rope-making steel wire. The surface of the steel wire The wear resistance and corrosion resistance after phosphating are greatly improved. Use phosphated steel wires to directly twist the steel wire ropes (the steel wires are not drawn after phosphating). This technology can be used to produce steel wire ropes for elevators in accordance with GB8903-2005. All technologies The indicators meet the requirements of national standards.
Current fatigue test data shows that the fatigue life of phosphate-coated steel wire ropes is about 3-4 times that of smooth steel wire ropes with the same structure, and 2-3 times that of imported steel wire ropes (under comparable laboratory conditions). Research on wear-resistant phosphating formulas also has the possibility of substantial improvement.
Manganese phosphating is wear-resistant phosphating, which can completely solve the wear problem of the wire rope during use. The traction elevator relies on the friction between the wire rope and the traction sheave groove. The manganese phosphating coating Elevator wire ropes are very suitable for use in traction elevators. The improvement in wear resistance greatly extends the service life, and the quality stability and safety are also improved at the same time. For reference only
