Product description

Steel wire rope is a helical wire b★β↓undle made of steel wires with mechanicaΩ₩λl properties and geometric dimensions that meet ≈≈the requirements, twisted together ac‍®εcording to certain rules. The ∞₽wire rope is composed of steel wiλ≤∏πre, rope core and gr≠®✘ease. A steel wire rope is a rope that is twist→β₽ed into strands from mult↔γiple layers of steel wires, and then a certain ‌≤number of strands are twisted in ♦σto a spiral shape with a certa ♦in number of strands as tλ✔¶he center of the rope core. In material handl₹×ing machinery, it is used for lift←∑&λing, traction, tensioning and carryi∑§±πng. The steel wire rope has high st↑​rength, light weight, ←<stable work, not easy to break the π↕whole rope suddenly, and reliable work. In 1834,•☆∞ European Olubert inv←£ented the world's first steel wir₹★Ω₩e rope (smooth steel wire rope).™δ§ The Tianjin No. 1 Steel Wire Rope Factory ↕ established in 1939 was "↕÷the first metal product enterp$®☆↑rise in my country.

Wire rope composition

The wire rope needs to σσ±bear the effect of al £ ternating load during the use process, and←₹ its use performance is mainly ☆δ↔determined by the mechanical properties of the s♠♥↑§teel wire, the surfa×‍♦ce condition of the steel λλ♦ wire and the structure of theγ↑ε★ steel wire rope. The stee♠‍γ∞l wire material includes carbon steel or alloy ♦✔♥steel, which is formed by cold drawing o ∞•↔r cold rolling. The cross sectio&♣₹n of the steel wire ₩σhas round or special shape (T t€♣ype, S type and Z ty¶Ωpe). The special shape cross section steeα✔l wire is mainly used for th≥φ♦¥e production of sealed steel wire ropes. Hi★λgh tensile strength and toughness, and a‍€ppropriate surface trea♠Ωσ♠tment of steel wire to meet the needs of diffe¶δ™>rent environmental conditions.

rope core

The main function of the rope core≠₩ is to support the steel wire rope™≥÷™ to achieve a stable cross-sect ‌☆ional structure. The rope core include•↔↕s a steel core and a fiber core. The fiber core☆Ω¥ includes a natural fiber core and a synthe₹σεβtic fiber core, such as sisal, jute, cotton, etcσ∏★., and the synthetic fiber c↓≠ore includes polyethylene ‌σ≠and polypropylene filame∏♦∞​nts. The natural fiber core can store more greas•>™e to lubricate the wir"βπe rope and prolong the service life of theα₽±¶ wire rope.

Grease

Spraying grease dur ≤ing the twisting process $©®of steel wire rope has two main"₽ functions. One is to lubricate≤λ the wire rope to slow down the wear ε×on the surface of the steel wire. The other  ♠↕is that the grease can isolate th←₽>♦e surface of the steel wire ♥ >₽from oxygen in the air anγ>♦ d cause oxidation and corrosion to the wire ro₹¥±pe. Play an inhibitory roφφ↑le.
