Product description

Steel wire rope is a helical wire bundle made ofβ↔→ steel wires with mechanicaπ¥l properties and geometric dimensio <↑₩ns that meet the requirements•σ, twisted together according to certain ru"¶les. The wire rope is com≤↔posed of steel wire, rope core and grease₹×. A steel wire rope is a ₹¶β rope that is twisted into sλ↑★₩trands from multiple layers of&₩ steel wires, and then a certain number o∏π★™f strands are twisted☆ ≥↑ into a spiral shape w×∞♥ith a certain number o£↑≠↔f strands as the cente€>®$r of the rope core. In material handling§>™♣ machinery, it is used for lifting, traction, ∑∞>σtensioning and carrying. The steel wire ≥↕rope has high strength, light weight,  •£₽stable work, not easy to bre↑δak the whole rope suddenly,≈& and reliable work. In 1834, European♣₹ Olubert invented the world₹∏♥'s first steel wire rope (smooth steel✔₩≤ wire rope). The Tianjin No. 1 Steel Wire R♠ §ope Factory established in 1939∑σ was the first metal product enterprise in my c ≈☆₩ountry.

Wire rope composition

The wire rope needs to b♥♠✔ear the effect of alternating™‌<λ load during the use process, and its≠<ε use performance is mainly deterσ♦mined by the mechaniπ♦cal properties of the steel ±&wire, the surface condition of the steel wire a ←★nd the structure of the steel wire rope. The σ≥Ω↔steel wire material includes carbon ste<©el or alloy steel, which  €÷ is formed by cold drawing or cold rolling$∞β. The cross section of the steel wire hasε♦ round or special shape (T type, S type✔♣ φ and Z type). The special shape cross sectio↕γn steel wire is mainly used for the product ∞ion of sealed steel wire ropes. β♥High tensile strengt "αh and toughness, and appropriate surface treatmen•♣✔>t of steel wire to meet t↑"he needs of different environmental φδconditions.

rope core

The main function of the r∏≥∏ope core is to support the steel wire ro≈♠pe to achieve a stable cross-sectional structu&γ"re. The rope core includ←™★•es a steel core and a♣§≤∏ fiber core. The fiber c↕¥ore includes a natural fiber core and₩¶δ a synthetic fiber core, suc≥™‌h as sisal, jute, cotton, etc., and the sy&♦↔¶nthetic fiber core includes poly☆λ→ethylene and polypropylene filaments. The§δ£₹ natural fiber core can store mor♦≤e 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 funct£✘♥ions. One is to lubricate the wire•∏  rope to slow down the wear on the surface of ✔∞ ₽the steel wire. The other is tha•≤™λt the grease can isolate the surface of the s₽↔β∞teel wire from oxygen in the air and cause ox'↓idation and corrosion to the wire ro​β₩÷pe. Play an inhibitory role.
