Manufacturing method for hot extruded polyethylene zinc-aluminum alloy coated steel wire cable

Abstract

The invention discloses a manufacturing method for a hot extruded polyethylene zinc-aluminum alloy coated steel wire cable. A polyethylene sheath, a high-strength steel wire and a closed wire rope areincluded; the high-strength steel wire forms the closed wire rope after winding, processing and manufacturing; the surface of the closed wire rope is coated with a zinc-aluminum alloy layer; and theexternal of the closed wire rope is sleeved by the polyethylene sheath. The manufacturing technology of a hot extruded polyethylene zinc-aluminum alloy coated steel wire cable includes wire rod performing-surface treatment-drawing-finished product obtaining-surface inspection-performance testing-packaging-warehousing. Thus, force of gravity of the cable during the construction of a bridge can be reduced, and the bearing capacity of the cable can be increased; through the design of the closed wire rope, fatigue performance can be increased, which can be enhanced by 30% compared with traditionalcables, so that the bearing intensity of the cable can be further increased; and through an anticorrosive material filed in the internal of the cable, water vapor and rainwater cannot enter the internal of the cable, so that the moisture and corrosion resistance of the cable can be greatly enhanced, and the durability and service life of the cable during using can be prolonged.

Description

technical field [0001] The invention relates to the technical field of steel wire manufacturing, in particular to a method for manufacturing hot-extruded polyethylene zinc-aluminum alloy-coated steel wire cables. Background technique [0002] With the development of science and technology, span bridges are gradually increasing. During the construction of span bridges, cables are the lifeline of bridge construction. With the lengthening of span bridges and the widening of paths, the weighing force of cables continues to increase. In order to enhance the strength of the cables, the diameter and material composition of the cables are gradually increased, resulting in a sharp increase in the weight of the cables, resulting in a linear increase in the weight of the bridge and the cables. [0003] In order to meet the stable construction and safe use of the bridge, the components of the cables need to match the weight and width of the bridge, etc., resulting in an increase in the ...
