Product description

Steel wire rope is a h™♥♣​elical wire bundle made of steel↓α≠ wires with mechanical properties and ge₽φometric dimensions that meet the requirδ£←™ements, twisted together acc®​©ording to certain rules. The wire rope is compose£♠✘d of steel wire, rope core and grease. A ste <εel wire rope is a rope th<★₹&at is twisted into sββtrands from multiple layers of stee©¥© l wires, and then a certain number of s©φ$trands are twisted iΩ‌✔‌nto a spiral shape with a certain number ↕​>₹of strands as the cent<γ×er of the rope core. In ma‍£terial handling machinery, it i←>×s used for lifting, ↔¶&©traction, tensioning and ••¶carrying. The steel wire rope has highβ‍± strength, light weig÷≥<ht, stable work, not easy to break the whole r≠•ope suddenly, and reliabl∞♣→¶e work. In 1834, European O±‍lubert invented the world's first steel wire r≤ ope (smooth steel wire rope). The Tianjin No. 1 ←‌Steel Wire Rope Factory established in 1939 wφγ₽as the first metal product enterprise in my count¥'™≈ry.

Wire rope composition

The wire rope needs to bσ™↑≈ear the effect of alternating load d★¥uring the use process₩‍≥, and its use performance ¥₽∏is mainly determined by th¥÷∞∑e mechanical propert©§ies of the steel wire, the surface conditi§™on of the steel wire and the structure of the st₽π∑eel wire rope. The steeσ↓≠↔l wire material includes carbon steel or alloy st↓πΩeel, which is formed by cold drawing &∞or cold rolling. The cross section o↑£f the steel wire has round or special≠‍ shape (T type, S type and Z type). The special∏"‌‍ shape cross section steel wiπβre is mainly used for the production of seaΩ₩led steel wire ropes. High λ∏♣£tensile strength and toughness, an∞←d appropriate surface treatment of steel wire to ∏α✘meet the needs of dif≈→ferent environmental conditions.

rope core

The main function of the rope core is to supp→↔€$ort the steel wire rope to achieve a stable✔₹ cross-sectional structure. The rope core™♦λ∑ includes a steel core and a fiber core. The fibe™λr core includes a natural fiber core and♥" a synthetic fiber core, such as sisal, j↑™δ≈ute, cotton, etc., and the s₩≤£♣ynthetic fiber core inclu↑>↔ des polyethylene and polypropylene filam‌★ents. The natural fiber core can ©≠ ₩store more grease to lubricate the ↕☆∑ wire rope and prolong the service life of the wi↕↔‌re rope.

Grease

Spraying grease dur→→ing the twisting process of steel wire rope h©≠'as two main functions. ≥δδOne is to lubricate the wire rope to slow d☆<own the wear on the surface✔  of the steel wire. The other is that the↕< grease can isolate the surface of the♦¥&★ steel wire from oxygen in th‍←e air and cause oxidation and corrosion to th ©e wire rope. Play an inh₩∞β§ibitory role.
