Steel Wire Rope
The steel wire rope is a helical steel wire bundle that combines the mechanical properties and the geometrical dimension according to certain rules. The steel wire rope is composed of steel wire, rope core and grease. The steel wire rope is firstly formed into strands by multilayer steel wire strands, and then the rope core is used as a center, and a certain number of strands are wound into spiral ropes. In material handling machinery, it is used for lifting, pulling, tensioning and carrying. The steel wire rope has high strength, light weight, stable work, and it is not easy to suddenly break the entire root and work reliably. In 1834, European Olubert invented the world's first steel wire rope (glossy steel wire rope). The first wire rope factory established in 1939 was China's first metal product company.
The use of the wire rope during the use of the role of alternating load, the use of performance is mainly determined by the mechanical properties of steel wire, steel wire shows the state and wire rope structure. The steel wire material consists of carbon steel or alloy steel, which is made by cold drawing or cold rolling. The cross section of the steel wire is round or shaped (T-type S-type Z-type). The special-shaped cross-section wire is mainly used for the production of sealed steel wire ropes. High tensile strength and toughness, and appropriate surface treatment of steel wire to meet the needs of different environmental conditions
