摘　　要：本研究采用包覆焊接法制备铜包钢线,并对其进行拉拔变形及退火处理。给出了经拉拔变形后的铜包钢线电阻率的计算公式。研究了不同的拉拔变形量和退火处理对其电阻率的影响;分析了其电阻率随加工工艺的变化规律。研究结果表明,铜包钢线的电阻率随其形变量的增加而升高。根据纯铜和钢丝原材料的电阻率,可计算经过不同拉拔变形量的导线的电阻率。随着铜包钢线退火时间的延长和退火温度的升高,其电阻率降低。通过实验数据分析,得到了铜包钢线的退火温度和退火时间分别与其电阻率关系的回归方程。The method adopted to manufacture CCS wire in this study is cladding, welding, drawing and annealing. The resistivity calculation formula of copper clad steel wire after deformation were given in the paper. The effect of drawing deformation, annealing temperature and annealing time on the resistivity were studied. The pattern of resis- tivity changes with processing technic was analyzed. Experimental results show that the resistivity of CCS wire is in- creased with the increase of the drawing deformation. According to the resistivity of primitive pure copper and steel wire, the resistivity of the copper clad steel wire were calculated with different drawing deformation. The resistivity of CCS wire is decreased with the increase of the anealling temperature and time. Through the experimental data a- nalysis, the regression equation about the relation of annealing temperature and annealing time of CCS wire with the resistivity are obtained.
