综述了SWRH82B盘条常见的折叠、结疤、微裂纹、划痕等表面缺陷和冶金缺陷,分析了产生的原因并提出预防措施;采用SEM、OM分析了中心网状渗碳体、中心区域马氏体、中心缩孔等内部缺陷的组织形貌,分析产生的原因和危害,并根据生产实际要求提出相应的解决方案和措施。
The common surface defects of SWRH82B wire rod were summarized,including overlap,scab,microcrack,scratch and metallurgical defect.The causes were analyzed and prevention measures were proposed.The morphology of the inner defects including central netting cementite,central martensite,and central pipe was analyzed by SEM and OM,as well as the causes and harms;and corresponding solving programs and measures were put forward based on the actual production requirements.
