Wire rope composition

Steel wire

The wire rope needs to bear the alternating load during the use of the wire rope, and its performance is used.

It is mainly determined by the mechanical properties of the steel wire, the surface state of the steel wire and the structure of the steel wire rope. The steel wire material consists of carbon steel or alloy steel, which is formed by cold drawing or cold rolling. The cross section of the steel wire has a circular or irregular shape (T-type S-type Z type), and the profiled cross-section steel wire is mainly used for the production of sealing wire rope. High tensile strength and toughness, and suitable surface treatment of steel wire to meet the needs of different environmental conditions.

Cord core

The main function of the rope core is to support the steel wire rope to achieve a stable cross-sectional structure. The rope core comprises a steel core and a fiber core, the fiber core comprises a natural fiber core and a synthetic fiber core, a natural fiber core such as sisal, jute, cotton thread, etc., and the synthetic fiber core comprises polyethylene and polypropylene filaments. The natural fiber core can store more grease, lubricate the wire rope and extend the service life of the wire rope.

Grease

The grease is sprayed during the wire rope twisting process. Its main functions are two. First, the wire rope is lubricated to reduce the abrasion of the wire surface. Second, the grease can isolate the wire surface from the oxygen in the air, causing oxidation and corrosion of the wire rope. Play a suppressing role.
