Product description

Steel wire rope is a helic≠∏λal wire bundle made of steel wir₹∑↓ es with mechanical properties and geom®Ω↓etric dimensions that meet the requirements, twis←>γ∏ted together accordi‌"♦ng to certain rules. The wirα₩§Ωe rope is composed of steel wi& ✔₹re, rope core and grease. A steel wire rop₹→e is a rope that is twiste₽€d into strands from multiple l&σ'γayers of steel wires, and then a certain nu↓∑✘mber of strands are twisted ₽←≥✔into a spiral shape with a δ certain number of strands as th₽®$Ωe center of the rope core. In material hand♥λ$ling machinery, it is used for lifting, tracti↓≠φ✘on, tensioning and carrying. "♣©The steel wire rope has high stre∏↓€ngth, light weight, stable work, not easδ♥ ↓y to break the whole r♣←αεope suddenly, and reliable work. In 1834, Euro"↕pean Olubert invented the world's first ste₩♦δel wire rope (smooth st♦☆↓αeel wire rope). The Tianjin ±>No. 1 Steel Wire Rope Factory estab≥®≈lished in 1939 was the fir® ↔↕st metal product enterprise in my c•∞ountry.

Wire rope composition

The wire rope needs to bear theλ ↔ effect of alternating load during th™ε>e use process, and its use performanε↔≥∞ce is mainly determined b€★y the mechanical properties of the s♣÷¶teel wire, the surface condit∏≠ion of the steel wire and the structure of t®↓₩he steel wire rope. The steel wire material in €♦♣cludes carbon steel or alloy steel, ×ε≥which is formed by cold draw<&↔&ing or cold rolling. The cross se™¥ction of the steel wire has round or special sh€<¥≈ape (T type, S type and Z type). The special sha♣↔÷pe cross section steel wire iλδ‌s mainly used for the production of sealed st₹¥eel wire ropes. High tens ☆ile strength and toughness, and appropriate su"∏πrface treatment of steel wire to meet the ne✘≤"♣eds of different envir‌↓÷←onmental conditions.

rope core

The main function of ♥≤the rope core is to suppor£§t the steel wire rope to achieλ¶★≈ve a stable cross-sectional stru★×cture. The rope core includes ¶δ∑λa steel core and a fiber core↕₹∞×. The fiber core includes a natural fiber core ×∞®φand a synthetic fiber core, such as sisal, juteσ¥×↓, cotton, etc., and the synthetic fibγ✘er core includes poly≈¶γethylene and polypro✘$pylene filaments. The natural • ₩fiber core can store more grease to ←✘☆>lubricate the wire rope and prolong the s₩∑ ervice life of the wire rope.

Grease

Spraying grease dur≤¶≤ing the twisting procε™✘ess of steel wire rope has two ✘≈∑ main functions. One is to lubricate the wiγβ₽re rope to slow down the wear on the surfac"α™e of the steel wire. The other is that t↕•he grease can isolate the surface of the steel γ₩ ≠wire from oxygen in the air and cause oxidat♦™ion and corrosion to the wire rope. Play a±© n inhibitory role.
