Product description

Steel wire rope is a helical wire bundle £≥₩•made of steel wires with mechan↔λ≠§ical properties and geometric di≠¶mensions that meet the reqσ‍αuirements, twisted together accor☆γ> ding to certain rules. The wi¶σ✔£re rope is composed of steel wire, rope core and ♦ grease. A steel wire rope is a rope ₽&that is twisted into∞<" strands from multiple layers of steel w •ires, and then a certain number of™→"$ strands are twisted iλ¥♣nto a spiral shape wit≈♥h a certain number of strands as the c±♣≠★enter of the rope core. In material han₩​dling machinery, it is used for lifting,$★↕£ traction, tensioning ←↕and carrying. The steelγ♠★☆ wire rope has high strength, light weight, ♠÷☆✘stable work, not easy to₽‍​ break the whole rope sud​φ≥γdenly, and reliable work. In 1≤ε≥834, European Olubert i✔♥≥σnvented the world's first steel wire rope (sm>≠"∑ooth steel wire rope). ♠€λ The Tianjin No. 1 Steel Wire Rope Fact≠₩®★ory established in 1939 was theφ∑& first metal product enterprise₹¶‌ in my country.

Wire rope composition

The wire rope needs to bear the effect of alter€β≥nating load during the use ®¶•♥process, and its use performa<←✔<nce is mainly determi✘♥←•ned by the mechanical properties of the steel wir✔↓e, the surface condition of the steel wire and ₩λ ‍the structure of the steel wir₽$<e rope. The steel wire material includes carbon €λsteel or alloy steel, whicΩ h is formed by cold drawin♣≤™g or cold rolling. The cros"→¥ s section of the steel wire ha↓∏φs round or special shape (T type,₹ε>± S type and Z type). The special shape∞& cross section steel w∞•£ire is mainly used f>↔or the production of sealed ¶‍≥ steel wire ropes. High ten> ♥←sile strength and toughness,≈¥÷ and appropriate surface treatment of steel ε wire to meet the needs of different envi♣®•₩ronmental conditions.

rope core

The main function of the rope core is to support ₹ the steel wire rope to achieve a stable cross-seΩ‍ctional structure. The rope core i≥φα∏ncludes a steel core and a fiber core. The fiber ₽λ♣core includes a natur✘ "σal fiber core and a synthetic fiber core, such  ¶ as sisal, jute, cotton, etc.,α$"> and the synthetic fiber core includes poly‌‌ethylene and polypropylene filaments. T♦☆he natural fiber core can store more'§λ grease to lubricate the wire r₹±×←ope and prolong the se¶∞©βrvice life of the wire rope.

Grease

Spraying grease during the t↕™₩wisting process of steel wire rope hπ ≈↔as two main functions. One is to★‌≈× lubricate the wire rope to slow down the we₽φ÷ar on the surface of the steel wire. The other is α♣ that the grease can i↔ ∑solate the surface of the steel wire from oxygen ↔±✔ in the air and cause oxidation and corro✔∑≈sion to the wire rope. Play an inhibitory role>σ ↔.
