摘要
利用JSM-6490扫描电镜分别对原材料（Φ5．5mm）和断丝严重道次的线材进行横向和纵向截面的观察，并与拉拔性能较好的线材作比较。分析ER55-G盘条钢拉拔断丝的原因，阐述贝氏体对盘条钢拉拔性能的影响。指出断丝的主要原因为组织不合格，并提出了相关解决措施。
By observating the raw material（Φ5. 5mm）and cross sections of broken steel wire from crosswise and lengthwise with JSM - 6490 SEM and comparing the steel wire with good drawing performance, the causes of drawing breakage of ER55-G are analyzed and effect of bainite on drawing performance of steel wire rod is discussed. Meanwhile, the paper points out improper microstructure is the main cause of drawing and corresponding measures are put forward.
