Mining patent

Manganese phosphating wear-resistant coated steel wire rope is the only steel wire rope with wear-resistant protective coating in the world today, because it has the longest fatigue life among steel wires of the same structure, that is, the best fatigue resistance, and it is also the most advanced technology in wire rope manufacturing industry in the world today. This technology is an invention patent of China, and many enterprises have been authorized to produce patents, including cranes, elevators and manganese phosphating wear-resistant coated steel wire ropes for mining. The manganese phosphating wear-resistant protective coating on the surface of steel wire is represented by the film weight of manganese phosphating wear-resistant coating. The film weight of manganese phosphating wear-resistant coating on elevator steel wire surface is generally 15-30g/m2, and the manganese phosphating wear-resistant coating on mine steel wire rope can reach 30g/m2. Manganese phosphating wear-resistant coated wire rope is an upgraded product of various smooth wire ropes. Therefore, when purchasing manganese phosphating wear-resistant coated steel wire rope, it must be in the contract. Smooth steel wire rope does not have any wear-resistant protective coating, which belongs to backward technology and is also an obsolete product.
