Phosphated coated steel wire rope (Chinese patent), the steel wire is phosphating with manganese or zinc manganese, the surface of the steel wire is very wear-resistant, effectively suppressing the occurrence of fretting wear. It is an upgraded product of smooth steel wire rope, used in atmospheric environment. The service life far exceeds the smooth steel wire rope of the same structure, including the imported smooth steel wire rope. (At present, the fatigue life of the phosphating rope is about 2-3 times that of the smooth rope. After the research on the wear-resistant phosphating solution, it may be large. The range is increased and the fatigue life can be compared by fatigue test.
The phosphating film is 3-60 g/m2. After the phosphating of the steel wire, the wire rope is not drawn, and the steel wire rope is directly twisted. Note: the zinc phosphating for drawing cannot be confused with the manganese phosphating of the steel wire. This technology is suitable for almost all types of wire ropes, such as elevator traction wire ropes, important use wire ropes, mine wire ropes, etc.
