摘　　要：用扫描电镜、大型金相显微镜观察分析SWRH82B盘条拉拔断丝样,结果表明:造成断丝的主要原因是盘条中的网状渗碳体、马氏体超标。根据这一结果,提出了改善SWRH82B盘条质量的建议。The broken wire sample of SWRH82B steel was analyzed by SEM and metalloscope. The resuit showed that the main reason of wire broken in direct drawing was high network cementite and martensite ontent in hot - rolled rod. Furthermore, suggestions were put forward to improve the quality of wire rod.
