Product description

Steel wire rope is >§Ωa helical wire bundle made >× ↑of steel wires with mechanical properti&↓es and geometric dimensions that mee¥‍♦≥t the requirements, twisted together according↕γ to certain rules. The wir ≥φe rope is composed of steel wire, roα÷♦pe core and grease. A steel wi♦¶re rope is a rope that is twisted into strands ☆✘☆from multiple layers of steel wires, and then >€a certain number of strands ar™&λ±e twisted into a spiral shape with a cert€£ain number of strands as the ce★÷≈nter of the rope core. In material han‍♠↓dling machinery, it ​&is used for lifting, trac₽→♦tion, tensioning and carrying≈¶&Ω. The steel wire rope has high strength, ∞∑​γlight weight, stable work, not easy to break t★∏he whole rope suddenly, and reliabl®₽e work. In 1834, European Ol←‌ubert invented the world's firs<∑t steel wire rope (smoo±<®™th steel wire rope).✘≠✘ The Tianjin No. 1 Steel Wire Rope Fac✘©α↕tory established in 1939 was the first metal pr$£oduct enterprise in my country.

Wire rope composition

The wire rope needs to bearβ> the effect of alternatinε↔g load during the use process, and its use p∏βerformance is mainly det→γermined by the mecha↕<™nical properties of the steel wire,₹•★ the surface condition of the steel wi β re and the structure of the steel wire ro©βpe. The steel wire material includes carbon ste♣₹↕el or alloy steel, which is formed by colε↑d drawing or cold rolling. Th∞±‌e cross section of the steel wi&βre has round or special shape (T type, λ∞S type and Z type). The speci‌←‌≠al shape cross section ✘∞"≤steel wire is mainly used for the product>♥ion of sealed steel ★γwire ropes. High tenπ¥sile strength and toughneλ₽ss, and appropriate surfa≤★♠£ce treatment of steel ©'wire to meet the needs of differ↔↕₽σent environmental conditions.

rope core

The main function of the rope core is​> to support the steel wire rope to achiev‍>e a stable cross-sectional structure"♠. The rope core includes a steel↕↕ core and a fiber core. The fiber core inc>¶∑¥ludes a natural fiber core✘☆★• and a synthetic fiber↔♦ core, such as sisal, jute, cotton, etc., and∑α the synthetic fiber cor​ e includes polyethylene and polypropylπΩ>§ene filaments. The natural fiber core ca>♥n store more grease to lubricate the wire rope ε€¥and prolong the service lif€¶λ₽e of the wire rope.

Grease

Spraying grease during th'©¶e twisting process of steel wire rope≥←↓Ω has two main functions. One is to l≥£★γubricate the wire rope to s™®₩low down the wear on the≤★ surface of the steel wire. Tσ♦≠εhe other is that the grease can iso∏‍♣>late the surface of the steel wire "±$Ωfrom oxygen in the air and cause oxidation and ↔γ≈₽corrosion to the wire rope. Playλ♥Ω an inhibitory role.
