The steel wire is made of high-quality carbon steel, which can achieve high strength after repeated cold drawing and heat treatment. Workplaces such as wet or open air environments can use wire ropes twisted from galvanized steel wires to enhance rust resistance.
Wire ropes are standard products in various industrial countries. The diameter, number of strands, number of steel 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, the wire rope is mainly broken due to metal fatigue caused by repeated bending when it goes around the pulley and the drum. Therefore, the ratio of the diameter of the pulley or the drum to the wire rope is an important factor in 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 application. If the wear, corrosion degree of the surface layer of the wire rope or the number of broken wires in each twisting pitch 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.
