通过对超细铜线拉制过程中断线断口的显微分析

找出了超细铜线拉制时断线的原因。认为断线产生的原因包括铜线坯的气孔、疏松、夹杂、表面缺陷、塑性不足以及铜线变形不均、变形力过大、工模具损耗、设备精度及平稳性等。在缺陷分析及生产实践的基础上提出了断线的解决对策。认为通过原材料优选、模具优化、润滑剂合理选择以及设备优化等措施可大大减少断线的发生

实现超细铜线的正常生产。

Through analyzing fracture morphology of line breaking in ultra-fine copper wires during drawing process

origination of line breaking was approached.Some defects are responsible for the occurrence of line breaking

such as gas hole

porosity

inclusion

surface defects and inadequate plasticity in the copper wire billets

and uneven copper line deformation

large deformation force

loss of tool as well as precision and stability of the equipment.Based on defects analysis and practical production

countermeasures were presented.Through optimizing raw materials and mould

and selection of lubricant as well as equipment optimization

occurrence of line breaking can be significantly decreased

realizing the normal production of copper wire.
