For friction-driven wire rope hoisting equipment, such as elevator wire rope or coal mine hoist wire rope, the more wear-resistant the wheel groove and wire rope, the better.
Phosphating coated steel wire rope is produced by patented technology (innovative technologies are all patented technologies), and steel wire is phosphatized by manganese series or zinc-manganese series, all of which are wear-resistant phosphating, which can greatly improve the wear resistance and corrosion resistance of steel wire surface. The failure process of wire rope is fretting fatigue. After phosphating treatment, it is not easy to wear and rust, which greatly prolongs the fatigue life. The fatigue test data show that the fatigue life of phosphating coated steel wire rope is 3-4 times that of smooth steel wire rope with the same structure, and it is still possible to greatly improve it. Units with their own fatigue testing machines should do fatigue tests for comparison, and the data of their own fatigue life tests are the most credible.
Using manganese or zinc-manganese phosphating to improve the wear resistance and corrosion resistance of steel materials has a history of nearly a hundred years in the mechanical processing industry, and the effect is obvious. The surfaces of automobile steel gears, worm gears and engine piston rings are all treated with manganese phosphating films, which have excellent wear resistance and corrosion resistance. The principle of patented technology of phosphating coated steel wire rope is also to improve the wear resistance and corrosion resistance of steel wire surface. After the surface treatment of steel wire, its wear resistance far exceeds that of greasing. The fatigue life of manganese phosphating coated steel wire rope is the longest, and the service life is proportional to the fatigue life.
