Production technology of copper-clad steel wire in soft state

Abstract

The invention relates to a production technology of a copper-clad steel wire in a soft state. The production technology successively comprises the following steps: drawing; tempering under high temperature; carrying out electro-deposition pretreatment; carrying out acid electrolysis; washing; carrying out pretreatment of electro-deposition; washing; carrying out electrodeposition thick treatment; washing; carrying out anti-oxidation processing; drying; drawing; washing; carrying out anti-oxidation processing; tempering under high temperature; polishing; carrying out anti-oxidation processing; and spooling to obtain a finished product. An advantage of the production technology of the copper-clad steel wire in the soft state is that an elongation rate of the produced copper-clad steel wire is greater than or equal to 8%, wherein the elongation rate, which is compared with an elongation rate of a copper-clad steel wire produced by a traditional tempering technology, can be enhanced by at least more than one time..

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 increasingly used in professional communication fields, such as data centers, financial insurance, industrial automation, transportation, 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 cables to twisted pairs and optical fibers. Twisted pairs have evolved from the original category 1, category 3, and category 5 to the current category 5, category 6, category 6, and category 7. Nowadays twisted pair wires use very high-priced pure copper wires as inner core conductors. my country is a country with scarce copper resources, so it has become an urgent task to find alter...

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, 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
