Production process of soft copper-clad steel wire

Abstract

The invention relates to a production process of a soft copper-clad steel wire. The production process of the soft copper-clad steel wire successively comprises the steps of drawing, high-temperature tempering, electro-deposition pretreatment, acid electrolyzation, washing, pretreatment electro-deposition, washing, thick processing electro-deposition, washing, anti-oxidation, drying, drawing, washing, anti-oxidation treatment and ammonia-decomposition high-temperature tempering. The production process of the soft copper-clad steel wire has the advantages that the 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 process.

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...

Problems solved by technology

[0023] 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, the elongation rate will decrease rapidly, and the elongation rate of the finished product can only reach about 4%. 2. The drawing oil remaining on the surface of the steel wire after rough drawing and fine drawing is difficult to clean in the pickling process. Once the cleaning is not complete, it will affect the bonding force between the steel wire and the copper layer, reducing the yield of the product
