| 摘 要： | 某条材厂生产SWRM6盘条时，在拉拔过程中出现异常断裂。通过宏观观察、扫描电镜及金相显微镜对断裂试样进行了深入分析，结果表明，盘条的脆性断裂与组织中的铁素体晶粒粗大及晶界析出的渗碳体密切相关，因此，应当通过适当降低相关工艺温度，以及冷却时尽量避开有害温度区间等措施解决。 |
| 关 键 词： | 盘条 断裂 晶粒粗大 渗碳体 |

| Abstract: | SWRM6 wire rod happened to break unconventionally when drawn in a strip mill plant. The broken sample was analyzed carefully by macroscopical inspection, electronic scanning microscope and metallographic microscope. The result shows that brittle fracture of the wire rod is concerned mainly with coarse ferrite grain and cementite which separates out along crystal boundary. So the correlative technologic temperature should be reduced and the disadvantageous temperature area should be avoided when the rod cools. |
| Keywords: | wire rod fracture coarse ferrite grain cementite |
