Product description

Steel wire rope is a£​✔ helical wire bundle made of steel wires witλ★↑h mechanical properties and geometric dimensio₩‌ns that meet the requirements, twisted togethα✔er according to certain rule♣®s. The wire rope is composed of€  steel wire, rope core and grease. A steel wire ≤♦rope is a rope that is ‍ twisted into strands from multiple laα★yers of steel wires, and then a certain number of ™ strands are twisted↓¥‍ into a spiral shape with a certain number of ∑☆€strands as the center of the rope core. In≠♣ material handling machiner♠↔y, it is used for lifting, traction, tensionin‍★≥g and carrying. The steel wire rope •ββ≥has high strength, light weight, stable work♣εσ®, not easy to break the whole rope suddenly,♥☆' and reliable work. In 1834, European'λ∑§ Olubert invented the world's first steel ✔±♥wire rope (smooth steel wire φΩ®rope). The Tianjin N÷®o. 1 Steel Wire Rope Fac<™×λtory established in 1939 was tΩ±φhe first metal product enterprise in my country.λπ$φ

Wire rope composition

The wire rope needs to bear the effect of©φ® alternating load during the use process, an≤☆♣d its use performanc¥≈σ♠e is mainly determined by the mechanical pro♣¥εεperties of the steel w±∏&∏ire, the surface condition of the steel≥​ wire and the structure of tγ↔he steel wire rope. T★‌✔​he steel wire material includes cφ↑≈÷arbon steel or alloy steel, which is formed by ♥₹✔₽cold drawing or cold rolli¥$₩≥ng. The cross section of the steel wire has ✘✘₽γround or special shape (T type, S tyε§pe and Z type). The special shape cross sectio<↔÷≈n steel wire is mainly used fo♠π©r the production of sealed steel wirλ"¶e ropes. High tensile strength ✘ε$γand toughness, and appropriate sur÷✘₹face treatment of steel wire to meet®© the needs of different envλ♥"¥ironmental conditions.

rope core

The main function of the rope core is to♥₹← support the steel wire rope to a€®chieve a stable cross-sectional structure. Th¥↔e rope core includes a steel cσ§±↓ore and a fiber core. The™π® fiber core includes a natural fiber core anσφ✔πd a synthetic fiber core, such as sisal, jute, co•★ ¶tton, etc., and the synthetic ★♠ fiber core includes polyethylene and α&polypropylene filaments. The natural fiber ☆β♣core can store more grease to lubricate the wα<₹ire rope and prolong the service life✔∑✔→ of the wire rope.

Grease

Spraying grease during the t׶ε¶wisting process of steel wire rope has two mλ≥αain functions. One is to lubricate the wire rope φ®©>to slow down the wear on the™☆♣£ surface of the steel w≤←ire. The other is that the greλ<$ase can isolate the surface of the steel wi♥Ωre from oxygen in the air and cause ↓ε✔oxidation and corrosion to the wir©&e rope. Play an inhibδαλitory role.
