Product description

Steel wire rope is a ∏✔÷helical wire bundle made of stee←÷l wires with mechanical ≥π↓↕properties and geometric dimensionγ'↓s that meet the requirement↓<★≠s, twisted together according to ✘♦÷βcertain rules. The wire rope is§γ♥¶ composed of steel wire, rope core and grease. A ©$$>steel wire rope is a rope that iσ∞s twisted into strands from multiple layer ←βs of steel wires, and then a certain n₹&umber of strands are twisted into a ♦♥‌αspiral shape with a certain number♥§★≈ of strands as the center of the rope core. In m‍ε¥aterial handling machinery, it is us₹→←↔ed for lifting, traction, tensioning an ≥λΩd carrying. The steel wire rope has high strength✔εγ±, light weight, stable worγλ←φk, not easy to break the whole©★> rope suddenly, and reliable work. In 1834, ☆φ₹"European Olubert inven₩♠‍€ted the world's first •↕steel wire rope (smooth steel wire rope). Th₩>γ e Tianjin No. 1 Steel π←Wire Rope Factory established in 1939 was t∞​•he first metal product enterprise in σ₹↕Ωmy country.

Wire rope composition

The wire rope needs to bear the effect of ¥≠☆↑alternating load during the use process±¶≤÷, and its use performance is mainly deter$→εΩmined by the mechani‍γ×™cal properties of the steel wire, the surfa∑​β≠ce condition of the steel wire and the struc¥↕ ♣ture of the steel wire rope. The steel wire m§¶♣aterial includes carbo₹γα✔n steel or alloy steel, which is formed by colδ☆&d drawing or cold rolling. The cross section of t₽>€ he steel wire has round or special shape '₹(T type, S type and Z type). The special shape c¥β®&ross section steel wire is mainly usedε•β for the production of sealed steel wire ropes•σ"₩. High tensile streng↕δ♥∑th and toughness, and appropriate surface tr≠​ ↑eatment of steel wire to meet the need☆©∏§s of different environmental conditions.

rope core

The main function oΩ‍•f the rope core is to support the steel wire rope‌®"  to achieve a stable crossσ↓-sectional structure. The rope ↑♦£core includes a steel core and a fi→δ₽βber core. The fiber coreλλ includes a natural fiber Ω<core and a synthetic fiber cor♦₽∏e, such as sisal, jute, cotton, etc., and the syn≤α±<thetic fiber core includes polyethylene and polypπ ∑ropylene filaments. The natural fiber cor§←≤™e can store more grease to lubricate the wire ropΩ×e and prolong the service life of the wire r≤€φope.

Grease

Spraying grease during th ₹♥e twisting process of≥& • steel wire rope has two main functions. ¥¥'One is to lubricate the wi‍✘re rope to slow down the wea ÷✔r on the surface of the steel wire. ¶₩The other is that th←σ→e grease can isolate the<•β surface of the steel wire from oxygen in the "≈air and cause oxidation and corrosion to the wi₹±®≠re rope. Play an inhibitory ro ∞le.
