steel wire
The steel wire rope needs to bear the action of alternating load during the use process, and its performance
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 includes carbon steel or alloy steel, which is made by cold drawing or cold rolling. The cross section of the steel wire is round or special-shaped (T-type, S-type, Z-type). The special-shaped cross-section steel wire is mainly used for the production of sealing wire ropes. High tensile strength and toughness, and suitable surface treatment of steel wire to meet the needs of different environmental conditions.
rope core
The main function of the rope core is to support the wire rope to achieve a stable cross-sectional structure. The rope core includes steel core and fiber core, fiber core includes natural fiber core and synthetic fiber core, natural fiber core such as sisal, jute, cotton thread, etc., synthetic fiber core includes polyethylene and polypropylene filament, etc. The natural fiber core can store more grease, which can lubricate the wire rope and prolong the service life of the wire rope.
Grease
There are two main functions of spraying grease during the twisting process of steel wire rope. One is to lubricate the steel wire rope to slow down the wear of the steel wire surface. act as an inhibitor.
