Manufacturing method of steel wire with alloy plated layer, steel wire and steel wire rope

Abstract

The invention discloses a manufacturing method of a steel wire with an alloy plated layer, the steel wire and a steel wire rope, and relates to the technical field of manufacturing and production of steel wires. The manufacturing method of the steel wire comprises the following steps that 1, a steel wire matrix is obtained; 2, the obtained steel wire matrix passes through a zinc pot with molten zinc liquid to obtain a steel wire matrix plated with a zinc layer, the steel wire matrix plated with the zinc layer is subjected to mechanical wiping treatment, and the steel wire matrix with an iron-zinc alloy layer on the surface or the steel wire matrix with the iron-zinc alloy layer and a pure zinc layer on the surface is obtained; 3, the obtained steel wire matrix with the iron-zinc alloy layer on the surface is pickled to remove the pure zinc layer on the surface of the steel wire matrix, and the steel wire matrix with the iron-zinc alloy layer on the surface is obtained; and 4, the obtained steel wire matrix with the iron-zinc alloy on the surface is drawn to obtain the steel wire with the required size. The steel wire produced by the method is beneficial to improving drawing and twisting speed and improving production efficiency.

Description

technical field [0001] The invention relates to the technical field of steel wire production and manufacturing, in particular to a method for manufacturing steel wire with an alloy coating, a steel wire and a steel wire rope. Background technique [0002] As a reinforcing material, steel wire rope has been widely used in rubber, plastic and other products. The difference in coating structure of the steel wire in the steel wire rope greatly affects the performance of the product, and the research on the coating has attracted more and more attention from the industry. Especially hot-dip galvanized products have excellent performance and promising application prospects. [0003] There is a pure zinc layer on the surface of the steel wire in the related art, because zinc is a metal with poor torsion resistance, which can reduce the speed of the steel wire during twisting and affect the production efficiency. Although the existence of the pure zinc layer can improve the corrosi...

[0003] There is a pure zinc layer on the surface of the steel wire in the related art, because zinc is a metal with poor torsion resistance, which can reduce the speed of the steel wire during twisting and affect production efficiency

Although the existence of the pure zinc layer can improve the corrosion resistance of the steel wire rope, it also reduces the fatigue resistance of the steel wire rope; Affects processing performance, but also affects performance at the customer's site
