Phosphating coated steel wire rope is a patented technology that can be used to produce elevator wire ropes that comply with the national standard GB8903-2005 elevator wire ropes. The production process is to first phosphate the rope-making steel wire, giving priority to the manganese-based phosphating or zinc-manganese-based phosphating formulas. Both phosphatings are wear-resistant phosphating, which can greatly improve the wear resistance of the steel wire surface. and corrosion resistance, thereby inhibiting the occurrence of fretting fatigue and greatly extending the service life.
The phosphating-coated elevator wire rope and the smooth elevator wire rope were subjected to fatigue tests until the strands were broken. The fatigue life of the phosphating-coated elevator wire rope was 3-4 times that of the smooth elevator wire rope, and the maximum was more than five times. For any industrial product, such a significant increase in service life is a revolution in manufacturing technology. If the company has a fatigue testing machine, please do the fatigue life measurement and comparison yourself. Such data is the most reliable.
Although the price of phosphate-coated steel wire rope is higher than that of smooth steel wire rope, because of its long service life, its average daily use cost is only about 30% of that of smooth steel wire rope, making it very cost-effective.
Manganese phosphating coated elevator wire rope completely solves the problem of early wire breakage in some elevator ropes. The product quality is highly stable. It is an upgraded product of smooth elevator wire rope. The elimination of smooth elevator wire rope is For sure.
