The performance of wire rope is mainly determined by its mechanical property, surface state and structure. Wire material include carbon steel or alloy steel by cold drawn or cold rolled, steel wire cross section is round or abnormity type (T S Z), special-shaped cross-section wire is mainly used for production line, has high tensile strength and toughness, and the appropriate surface treatment of steel wire to meet the needs of different environmental conditions.
The main function of the core is to support the steel wire rope to achieve a stable cross - section structure. Rope core includes steel core and fiber core, fiber core includes natural fiber core and synthetic fiber core, natural fiber core such as sisal hemp, jute and cotton thread, and synthetic fiber core includes polyethylene and polypropylene filament. The natural fiber core can store more lubricating grease, which can lubricate the wire rope and prolong its service life.
In the process of wire rope twisting, spray grease has two main functions. One is to lubricate the wire rope to reduce the wear on the wire surface.
