Product description

Steel wire rope is a helical→↑$ wire bundle made of stee‌♥♦✔l wires with mechanic✔×σ✘al properties and geometric dimen׶εsions that meet the requirements, twist→€₽♠ed together according to certain rules. Theγ♣ wire rope is composed ​₹σof steel wire, rope core anε∞d grease. A steel wire rope is a rope that is t∑∑γ$wisted into strands from multiple ≤Ω≤layers of steel wires, and then a certa‌∞εin number of strands are twisted into a spir♦γal shape with a certain number of strands as the★​★ center of the rope core. In material handling m→'achinery, it is used for lifting, traction, tensi¥Ω✘oning and carrying. The ste© ✘&el wire rope has high strength, light weight, st‍  able work, not easy to break€β←♦ the whole rope suddenly, a<←nd reliable work. In 1834, Europ$↓ean Olubert invented the world's first stee✔$l wire rope (smooth steel wire rope¶π). The Tianjin No. 1 Steel Wire Ropε↕e Factory established in 1939 was the♦π first metal product enterprise α<in my country.

Wire rope composition

The wire rope needs to bear the effect of alte♦₩ rnating load during the use process, and itsφ↕ use performance is mainly determined by th®γ"e mechanical properties of♥"≠• the steel wire, the surfac☆₩™®e condition of the steel w ₹ire and the structure of the≤∞ steel wire rope. The steel wire material includ≥σ☆♥es carbon steel or alloy s'★teel, which is forme​δ•÷d by cold drawing or cold rolling. The cr™'÷♣oss section of the steel wire has ro​™→und or special shape (T$≠≥ type, S type and Z type). The specia©₹l shape cross section stee™≈l wire is mainly used for the production of seal✔&ed steel wire ropes. High tensiΩ÷le strength and toug↓$☆×hness, and appropriate‍♣ surface treatment of steel wire to £©∏δmeet the needs of different envi₽'↓ronmental conditions.

rope core

The main function of the rope core i→®₽©s to support the steel wire rope to §​achieve a stable cross-s★↔ectional structure. The r§©©ope core includes a ste∏€el core and a fiber core÷®∏★. The fiber core includes a natural fiberσ ÷' core and a synthetic fiber core, €↔such as sisal, jute, cotton, etc., and the syntδ₽≥ hetic fiber core includes polyethylene and polypr© Ω​opylene filaments. The natural fiber core can sto↕&♦re more grease to lubricate the wir ♣♥e rope and prolong the service life of the wire ₽≠rope.

Grease

Spraying grease during the twist↕$πing process of steel wire rope h₹≠as two main functions. On☆✔λ<e is to lubricate the wire rop÷πe to slow down the wear on t÷©♥he surface of the steel wire. The other is tβ♠hat the grease can isolate the surface of t♦"✔he steel wire from oxyg≤∑en in the air and cause oxidation an∞£$d corrosion to the wire rope. Play β∞₹•an inhibitory role.
