摘　　要：观察82B盘条的组织,发现异常组织(马氏体、网状渗碳体)在拉拔时造成纤维裂纹,夹杂物不造成纤维裂纹,异常组织超过一定的尺寸会造成拉拔断丝,提出消除或减轻82B盘条异常组织的建议。To observe the microstructure of 82B wire rod. It is found that the abnormal mirostructure including martensite and net eementite in wire rod brings about fibre crackle in drawing, the inclusion do not bring about fibre crackle. The three kinds of abnormal mierostrueture can bring about wire drawing breaking as surpassing definite dimension. Some suggestions to eliminate or lighten the abnormal mierostrueture of 82B wire rod are put forward.
