Problems solved by technology

[0005] The soft copper-clad steel produced by the traditional production process has the following defects: 1. Although the high-temperature tempering process can soften the copper-clad steel wire, eliminate work hardening, and increase the elongation rate, so that the elongation rate reaches about 20%, the subsequent finished product drawing The process will cause work hardening of the wire rod, t...

Embodiment Construction

[0033] The present invention is further described below.

[0034] The production process of the soft copper-clad steel wire comprises the following steps:

[0035] (1) Drawing, the H08 steel wire with a diameter of 6.5mm or 5.5mm is used as the steel wire base material to peel off the scale, and then the steel wire after descaling is subjected to acid electrolysis, water washing, boronization, high-frequency heating and drying Dry, and finally draw the dried steel wire through a continuous drawing machine to a diameter between 1.8-2.4mm; boronization is to pass a single steel wire through a borax solution, and the temperature of the borax solution is controlled between 75-85°C , to form a boride film on the surface of the steel wire;

[0036] (2) High-temperature tempering, put the drawn steel wire into a vacuum tempering furnace for high-temperature heat treatment, eliminate work hardening of the steel wire, improve plasticity, soften the steel wire, and facilitate subsequen...

Abstract

The invention relates to a production technology of a soft-state copper-clad steel wire. The production technology of the soft-state copper-clad steel wire successively comprises the following steps: drawing; high temperature tempering; electrodeposition pretreatment; acid electrolyzation; washing; pretreatment electrodeposition; washing; thick processing electrodeposition; washing; anti- oxidization; drying; drawing; washing; anti- oxidation treatment and ammonia-decomposition high temperature tempering. By using the production technology of the soft-state copper-clad steel wire of the invention, an elongation rate of the copper-clad steel wire is greater than or equal to 10%, which is more than one time of the elongation rate of the copper-clad steel wire produced by a traditional tempering technology.

Description

technical field [0001] The invention relates to a production process of a soft copper-clad steel wire. Background technique [0002] The continuous development of data communication cables is more and more used in professional communication fields, such as data centers, financial insurance, industrial automation, vehicles, military communications and other fields. Higher and higher requirements are put forward for the rate reliability, electromagnetic shielding performance and mechanical performance of data communication cables. Therefore, the transmission medium has also shifted from coaxial cable to twisted pair and optical fiber. Twisted pair has developed from the original category 1, category 3, and category 5 to the current category 5e, 6, 6e, and 7. The current twisted pair wires use very high-priced pure copper wires as the inner core wires. my country is a country with scarce copper resources, so it has become a top priority to find alternative materials for copper...
