Abstract

The invention discloses a steel wire rope which comprises a rope core and a rope strand. The rope stand is twisted on the rope core, gaps between the rope core and the rope strand are filled up with zinc wires, a zinc layer coats the rope strand, and an elastic material layer coats the periphery of the zinc layer. The zinc wires are filled into the gaps between the rope strand and the rope core under the action of external twisting force, so that the whole structure of the steel wire rope and the supporting function of the rope core are enhanced. Furthermore, the gaps between the rope strand and the rope core are filled up to enable the zinc wires, steel wires and surroundings to form a primary battery. The zinc wires form positive poles to be sacrificed to protect negative pole steel wires, so that the anti-corrosion function of the rope core is achieved and the service life of the rope core is achieved.

Description

technical field [0001] The invention relates to a corrosion-resistant steel wire rope. Background technique [0002] With the development of national infrastructure and the growth of the national economy, steel wire ropes have become more and more widely used in engineering construction, port terminals, ladle lifting, etc., and have basically achieved localization. With the development of the metal products industry, the quality of domestic steel wire ropes has also improved by leaps and bounds, and the breaking force and fatigue performance of steel wire ropes have basically reached the international level. However, the corrosion resistance of the steel wire rope, whether it is a smooth steel wire rope coated with grease or a steel wire rope with a galvanized surface, is difficult to reach the real quality level of steel wire rope in developed countries. For the 6*36SW+IR structural steel wire ropes used for lifting in ports, deep-sea oil fields, etc., the purpose of anti-...
