What does the national standard wire rope look like?
2022-09-08
The steel wire is made of high-quality carbon pot, which can reach high strength after repeated cold drawing and heat treatment. Workplaces such as wet or weather-demanding environments can use wire ropes twisted with zinc-coated steel wires to enhance rust resistance.
Wire ropes are standard products in various industrial countries. The diameter, number of strands, number of wires per share, tensile strength and sufficient safety factor can be selected according to the needs of use. Its specifications and models can be found in the relevant manuals. In addition to the wear of the outer layer steel wire, it is mainly due to metal fatigue caused by repeated dome when bypassing the slip and reel, and it is gradually broken. Therefore, the ratio of the diameter of the pulley or the reel to the wire rope is an important factor determining the life of the wire rope. If the ratio is large, the bending stress of the steel wire is small and the service life is long, but the mechanism is huge. The appropriate ratio must be determined according to the occasion of use. The wear of the surface layer of the pot wire rope, the degree of magic corrosion or the number of broken wires in each twisting distance exceeds the specified value, it should be scrapped.
Steel wire ropes are mainly used in hoisting, pulling and other transportation that require high-strength wire ropes.
