Product description

Steel wire rope is a helical wire bund↕↔§αle made of steel wires with mechanical prop₽±‌ erties and geometric∏₹π dimensions that meet the r<∞equirements, twisted togeth≤↓✔er according to certain rules. The wire rγλ‌ope is composed of s≤×teel wire, rope core and grease. A steel wire£™ rope is a rope that is twisted inπ♦to strands from multiple layers of steel w ₩↕ires, and then a certain number of strands aφ₹re twisted into a spiral shape with a©₽‌¶ certain number of s♥£trands as the center §‍☆of the rope core. In material handγ$±™ling machinery, it is used for lifting,δ Ω™ traction, tensioning and carryin>←αg. The steel wire rope has high strength, light ×∏±<weight, stable work, not easy to bre£Ω≈πak the whole rope suddenly, and reliable w←®‌ork. In 1834, European Olubert invented the wor'β₩​ld's first steel wire rope (smooth steel wire r¥¶×>ope). The Tianjin No. 1 Steel Wire Ro☆ε€↕pe Factory established in 1€"Ω 939 was the first metal product ​¶enterprise in my coun✘ &™try.

Wire rope composition

The wire rope needs to bear the effect of altern↑≥αating load during the ©✔ε'use process, and its use performance±↔ is mainly determined by the me♣φchanical properties of the steel wire, the surf‌$&δace condition of the steel wire and the stru‍ <cture of the steel wire rope. The↔  steel wire material includes∏‌ carbon steel or alloy steel, which is♦©∞‌ formed by cold drawing o<∞ r cold rolling. The cross section of the steel•δ¥↑ wire has round or special shape (T type↑λ, S type and Z type). The special shape cross ∏✘φ€section steel wire is mainly used for the prodλ®≥λuction of sealed steφ☆el wire ropes. High tensile strength and to&σ§λughness, and appropriate surface treatment o€‌f steel wire to meet the nee€→↑ds of different environmental conditions.

rope core

The main function of the rope core‍₩ α is to support the steel wire rope to achieve a sα table cross-sectional structure. ©βφ★The rope core includes a steel c♠ σ↑ore and a fiber core. ≥∑∞"The fiber core includes a natural•≠↑ fiber core and a synthetic fiber core, such∑∑≥ as sisal, jute, cotton, etc., and th>≥e synthetic fiber core includes p₹£ olyethylene and polypropylene filamen≤☆εts. The natural fiber core can store mor§✔↔e grease to lubricate the wire ↑¶★σrope and prolong the se♣"rvice life of the wire rope​€.

Grease

Spraying grease during the twisting process o‍ f steel wire rope has two main funct¶$♥ions. One is to lubricate the wire rop↓₩λ♥e to slow down the wear on the surface o★ ↓f the steel wire. The other is that the grease c™β$÷an isolate the surface of the st♥¥eel wire from oxygen in t>≥he air and cause oxidation and corrosion toΩ↕§ the wire rope. Play an inhibitory role.
