摘　　要：连铸纯铜杆废品存在严重偏心现象 ,中心有大量的气孔、缩松等缺陷 ,是导致纯铜杆硬度和强度不足、耐磨性差、导电性低的主要原因。通过将结晶器由单侧进水改为双侧进水 ,可解决偏心问题。将结晶器插入深度增加 ,可使气孔、缩松问题得到解决。The serious accentric and a lot of gas holes, porosities in the center for Cu scraped pole could lead to insufficient hardness and strength, lower wear resistance and electric conductivity. Change in cooling water entrance from single side to twin sides in the crystallizer could correct the accentric. Increase in inserted depth of crystallizer could eliminate gas hole and porosity.
