Product description

Steel wire rope is a helica$∏§l wire bundle made of steel w$≤σires with mechanical properties and geometric↕∞® dimensions that meet the requirements, t☆÷π‍wisted together according to certain rules.  ★‌The wire rope is composed of steel wir≤♦≈λe, rope core and grease. >₽↓≤A steel wire rope is a rope that is twisted i≥βnto strands from multiple ♦¥×€layers of steel wires, an∏★≠↓d then a certain number of strands are twisted in¶®↔to a spiral shape with a certain number of stαλ≤€rands as the center oδ≈f the rope core. In material handling ma 'chinery, it is used for lifting,∑∏ traction, tensioning and carrying∑Ω. The steel wire rope has hiλ₩∏gh strength, light weight, s♠∞ table work, not easy to break the wh&¥φ☆ole rope suddenly, and reliable work. In ♠®α1834, European Olubert invented the world's ↔€φfirst steel wire rope±☆↕ (smooth steel wire rope). The Tianjin No. 1 S♦₽teel Wire Rope Factory es®δtablished in 1939 was the first metal prodσ♣×≈uct enterprise in my country.

Wire rope composition

The wire rope needs to bear the ✔Ω‍effect of alternating load during×& the use process, and iγ ts use performance is ma↑∑↓inly determined by the mechanical properti♠↑es of the steel wire, the surface condition of ✔•₩the steel wire and the structure of the steel >¶♠εwire rope. The steel wire material includes carboλ>σ→n steel or alloy steel, which is forme♣•✔>d by cold drawing or∞$$ cold rolling. The cross section of the steel ↓"§πwire has round or special shape (T type, ♥©S type and Z type). Th∏♥e special shape cross section steel wire is mainl♥‍y used for the production o←γ>™f sealed steel wire ropes÷>≥✔. High tensile strength and toughness, a∑∑¶$nd appropriate surface treatφ®'δment of steel wire to meet the needs of diffe∑∞₹rent environmental condit★< $ions.

rope core

The main function of th≥✘¶€e rope core is to support the steel wire®± β rope to achieve a s↔Ω‍×table cross-sectional sΩ★≥tructure. The rope core includes a s←‍§teel core and a fiber core. The fiber c±≥♠φore includes a naturδσ↔al fiber core and a synthetic fiber core, s♦γ©uch as sisal, jute, cotton, et£₹ >c., and the synthetic fiber core includes  ♥✔ polyethylene and polypropyle​∞"≥ne filaments. The natur♦↕al fiber core can store more grease to lubrπ¶icate the wire rope andε€  prolong the service life of the wire rope.

Grease

Spraying grease during the twistλ ing process of steel wire rope has two main fu∏©↑€nctions. One is to lubricate the wire rope to sloε λ∞w down the wear on the Ω✘÷®surface of the steel wire. The other is ∏ that the grease can i‍<Ωγsolate the surface oφδf the steel wire from oxygen in th•→e air and cause oxidation and corro¥¥sion to the wire rope. Play an inhibitory ro<♠le.
