Abstract
The production process of the ultrahigh-strength and ultrahigh-zinc layer steel wire improves the strength and the zinc layer on the basis of the existing hot-dip galvanized steel wire, and comprises the following steps of: drawing raw materials, heat treatment, quenching, drawing and hot galvanizing. Firstly, drawing a raw material by adopting a high-quality high-carbon steel wire rod, and secondly, performing heat treatment to reduce a steel substrate structure to prepare for subsequent drawing; thirdly, quenching aims to improve the strength of the steel wire; fourthly, drawing, and drawing the steel wire subjected to heat treatment quenching again; and fifthly, directly hot-dip galvanizing the drawn steel wire by hot dip galvanizing, and obviously improving the zinc layer by singly controlling the linear speed of a linear wire drawing machine. Compared with the common hot-dip galvanized steel wire, the zinc content can be improved by 25-30%, the application range of the steel wire is expanded again, and the service life of the steel wire is prolonged.
Description
Technical Field
The invention relates to the technical field of monofilament paying-off tension structures of steel wire rope double twisters, in particular to a production process of ultrahigh-strength ultrahigh-zinc layer steel wires.
Background
At present, two common production processes of galvanized steel wires are provided: an electrogalvanizing process and a hot galvanizing process. Compared with hot galvanizing, the electrogalvanizing has the advantages of low production cost, low surface coating, poor corrosion resistance and rust resistance, short service life and limited application range. On the contrary, the hot galvanized steel wire is widely applied to various industries, has the advantages of corrosion prevention, rust prevention, prolonged service life of the steel wire, good stability after the steel wire is loaded, difficult deformation and good elasticity. Compared with the electrogalvanized steel wire, the service life of the conventional hot-dip galvanized steel wire is greatly prolonged, but the conventional hot-dip galvanized steel wire is only suitable for conventional products. For some high-precision products, the hot-dip galvanized steel wire still can hardly meet the requirements of the products in the using process and the service life.
Disclosure of Invention
The invention aims to solve the defects in the prior art and adopts a production process of an ultrahigh-strength and ultrahigh-zinc layer steel wire.
In order to achieve the purpose, the invention adopts the following technical scheme:
the production process of the ultrahigh-strength and ultrahigh-zinc layer steel wire comprises the following steps; s1, drawing the raw material, wherein the raw material is high-carbon steel wire rods;
s2, heat treatment, namely, carrying out heat treatment on the steel wire by adopting a naked flame furnace;
s3, quenching;
s4, drawing;
s5, hot galvanizing.
According to a further technical scheme, the hot galvanizing treatment of S4 is directly carried out after the steel wire is drawn in the S4, and the drawing speed is kept constant.
In a further technical scheme, a linear wire drawing machine is adopted for drawing in the S1 and S4.
