摘要

铜材质量与退火工艺是影响漆包线柔软性的重要因素。为提高漆包线的柔软性并满足高性能应用需求，文中聚焦相关影响因素分析了不同铜材和不同工艺制备的漆包线的金相组织、伸长率及回弹角，探究了铜材质量与退火工艺对漆包线柔软性的影响。结果表明，铜材中杂质元素越少、晶粒尺寸细化和组织均匀能有效提高漆包线的伸长率、降低漆包线的回弹角；在一段退火温度/二段退火温度为550 ℃/540 ℃且退火线速为70 m·min

−1

时，漆包线的伸长率和回弹角最佳，分别为44.1%和32.0°。

Abstract

Copper material quality and the annealing process are critical factors influencing the softness of enamelled wires. To enhance the softness and meet high-performance application requirements

the effects of these factors were investigated by analyzing the metallographic structure

elongation

and springback angle of wires prepared from different copper materials under various processes. The results indicated that lower

impurity content

grain refinement

and a uniform microstructure in the copper material effectively increased the elongation and reduced the springback angle of the wires. When the first annealing temperature/the second annealing temperature was 550 °C/540 °C and the annealing line speed was 70 m·min

−1

the elongation and springback angle of the enameled wire were the best

which were 44.1% and 32.0°

respectively.
