Mining patent inquiry

The steel wire rope used in coal mine must be wear-resistant to ensure its service life, especially when it rubs against the ground in inclined shaft of coal mine. Manganese phosphating coated steel wire rope is an invention patent of China. Many domestic enterprises purchase patents to authorize the production of manganese phosphating coated steel wire ropes for cranes, elevators, mines and so on. Manganese phosphating film on the surface of steel wire is a kind of wear-resistant protective coating, which is often used in mechanical parts to prevent fretting wear on the surface of steel wire and has good corrosion resistance. The greater the film weight of manganese phosphating film, the stronger the wear resistance. Generally, the film weight of manganese phosphating coated steel wire rope for crane is 15-30g/m2, and the film weight of manganese phosphating coated steel wire rope for mine can reach 30g/m2. Compared with mine smooth steel wire rope, the service life of manganese phosphating coated steel wire rope will be greatly improved. Manganese phosphating coated steel wire rope for mining is an upgraded product of smooth steel wire rope for mining, and smooth steel wire rope will be eliminated.
