Main components of wire rope
Steel wire
The wire rope needs to bear the action of alternating load during the use process, and its use performance is mainly determined by the mechanical properties of the steel wire, the surface condition of the steel wire and the structure of the steel wire rope. The steel wire material includes carbon steel or alloy steel, which is made by cold drawing or cold rolling. The cross section of the steel wire has a round or special shape (T-shaped, S-shaped and Z-shaped). High tensile strength and toughness, and appropriate surface treatment of steel wire to meet the needs of different environmental conditions.
The cord
primary role is to rope cord play a supporting role, in order to achieve a stable cross-sectional configuration. The rope core includes a steel core and a fiber core. The fiber core includes a natural fiber core and a synthetic fiber core, such as sisal, jute, cotton, etc., and the synthetic fiber core includes polyethylene and polypropylene filaments. The natural fiber core can store more grease to lubricate the wire rope and prolong the service life of the wire rope.
grease
Spraying grease during the twisting process of steel wire rope has two main functions. One is to lubricate the steel wire rope to slow down the wear on the surface of the steel wire. Second, the grease can isolate the surface of the steel wire from oxygen in the air and cause oxidation and corrosion to the steel wire rope. Play an inhibitory role.
