Product description

Steel wire rope is a helica‌‌★γl wire bundle made of≈"¥ steel wires with mechanical proper‌®​ties and geometric di♥♠©¥mensions that meet the requirements, twisted ∏★together according to←‌♣ certain rules. The wire rope is composed ★£$of steel wire, rope core and grease. A ∏ steel wire rope is a rope thaλ>α∑t is twisted into strands from multiplπ§φe layers of steel wires&₹♠✔, and then a certain numbe♦↕←πr of strands are twisted i∏♣nto a spiral shape with a certain number π←π₹of strands as the center of the rope core. ∑π In material handling machinery‍∏, it is used for lifting, traction, ten÷φ★sioning and carrying. The steel wire ±±×rope has high strength, light weigh∞β"t, stable work, not easy to break the®←☆≥ whole rope suddenly<γ©, and reliable work. In 1834, E£'uropean Olubert invented the world's first stβ©♠¥eel wire rope (smooth steel wire rope). Th↕₹e Tianjin No. 1 Steel Wir₹¶‍e Rope Factory established in 1939 was the ★¶first metal product ​₩¥>enterprise in my country.

Wire rope composition

The wire rope needs to ₹'¥ bear the effect of alternating load d✔÷λβuring the use process, and its use performan± δ>ce is mainly determined by the mechaniγ♣✘cal properties of the steel wire,£ ∑$ the surface condition of the s‍₽teel wire and the structure o✔ f the steel wire rope. The steel wire mater<∞÷ial includes carbon steel or alloy steel, which™×•§ is formed by cold drawing or cold rolling. T←&he cross section of α¶☆the steel wire has round or special shapeα™> (T type, S type and Z type). The s₽≈$pecial shape cross section steel wi∑<♣re is mainly used for the production oφ​<f sealed steel wire rope≥•'s. High tensile strength and toughness, anε<d appropriate surface treat→♦♠÷ment of steel wire to meet the ★≤♥±needs of different environmen™↔∏tal conditions.

rope core

The main function of the rope core is ±α±to support the steel wi₩Ω≤>re rope to achieve a stable cγ₹ ross-sectional structure. The ro∑→∑∑pe core includes a steel core and a fiber core€‌←σ. The fiber core includes a natural fiber≤≈× core and a synthetic fiber core, such as sisal, ↓σjute, cotton, etc., and tΩ¶he synthetic fiber cor ✔ e includes polyethylene and polypropy♠₹αεlene filaments. The ∏'≠natural fiber core can store more grease t™≥♣o lubricate the wire rope and prolong th♦∞φe service life of the wire ropeγ±​.

Grease

Spraying grease during the twist>ασing process of steel wi★✘€αre rope has two main functions. One is to π₩"lubricate the wire rope π'to slow down the wear on the ₩'surface of the steel wire£ . The other is that th♠×e grease can isolate  ®the surface of the s★ ₽↑teel wire from oxygen δ 'in the air and cause ∞∏¥×oxidation and corrosion to the wire rop​©♥e. Play an inhibitory role.
