Product description

Steel wire rope is a helical ÷↕ wire bundle made of steel wires with mechanica©♥l properties and geometric dimensions that σ•®meet the requirements, twisted toge∑≈ther according to certa₩‌©©in rules. The wire rope is composed of steel wπφαire, rope core and grease. A steel wir₽δ≠e rope is a rope that is twisted into stran∑αds from multiple layers 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 machine↕€ry, it is used for lifting,✔‌¥ traction, tensioning and carrying. The steel&♣ wire rope has high strength, li¥®φ↕ght weight, stable work, not easy to bre ×♦δak the whole rope suddenly, and reliable work. ®®↓In 1834, European Olubert invented ☆εδΩthe world's first steel wire rope (sε≥>mooth steel wire rope). The Ti÷‍<₽anjin No. 1 Steel Wire Rope Factory estabδ♥≥lished in 1939 was the first metal produ∞↕→αct enterprise in my country.

Wire rope composition α€±

The wire rope needs t↓©o bear the effect of alternating load durin"¶↓÷g the use process, and its use pαβ≠αerformance is mainly determined by↕♦© the mechanical properties ' of the steel wire, the surface condition of t±≠‌§he steel wire and the sΩ♠tructure of the steel wire ∞♥rope. The steel wire mater∞<©ial includes carbon steel o♦ΩΩr alloy steel, which is formedσ& by cold drawing or cold rolliφ♣∑ng. The cross section of the steel wire has r♥→↔£ound or special shape (T typeφΩ, S type and Z type). The special shape cro↑☆ss section steel wire is mainly≤∞  used for the production←Ω☆∏ of sealed steel wire r€©opes. High tensile strength and toughness, a®‍≈nd appropriate surface treatment of stee Ωl wire to meet the needs of different environmε♠πental conditions.

rope core

The main function of the rope core is¥±∞σ to support the steel wire rope to achieve σδ a stable cross-sectio>∞nal structure. The rope core i <¥↔ncludes a steel core and a fiber core. The fiber  ¥core includes a natural fi↔∑£✔ber core and a synthetic fiber core, such aΩ♥₽↕s sisal, jute, cotton, etc., and the synthetic♦β≤ fiber core includes polyethylene×♦ σ and polypropylene filaments.λγ The natural fiber core can store more grea₩↑∑®se to lubricate the wi§™<re rope and prolong the service li÷¥•"fe of the wire rope.

Grease

Spraying grease during>→¶ the twisting process of steel wireλ£< rope has two main functions. One is to lubri ∑§cate the wire rope t÷€Ω∏o slow down the wear on the surface of the φ←steel wire. The other is that the Ω♦↑&grease can isolate the surface of the stee↔↕l wire from oxygen in• ®• the air and cause oxidation $‌ελand corrosion to the wire rope. Play an inhibit×±ββory role.
