摘    要：铜杆的制造方法不同,铜杆内氧化亚铜粒子的粗细和数量也就不同,从而影响了拉线性能.在氧化亚铜粒子细且少时,对降低拉线断头率有利.改平模铸锭为连续铸锭是一种易于实现的改进方法。

Abstract: There are various manufacture processes of copper wire rod and also viarious sizes andquantities of Cu₂O particles in copper.As a result,there will be various structures and prop-erties of drawing of rod,Smaller and fewer Cu₂Oparticles will be helpful to for reduce frac-ture rate of drawing. An improvement of wire bar casted by horizontal mould to billet castedby horizontal continuous process is easy to achieve.
