摘要(Abstract)：

测量了1.35%Si无取向硅钢的静态CCT曲线,根据静态相变点测量了实验钢的动态CCT曲线,根据动态相变点设计了不同冷却速度的模拟热轧实验并利用EBSD技术对不同冷却速度的退火试样进行微观织构分析。实验结果表明:冷却速度越小,奥氏体向铁素体转变开始温度越高,再结晶程度越高,再结晶组织晶粒越粗大;热轧退火织构分布与在两相区终轧有明显关系,主要织构类型有旋转立方织构、{111}<121>织构、{111}<110>织构和立方{100}<001>织构;随着冷却速度上升,{111}<121>织构、{111}<110>织构和立方{100}<001>织构含量下降,旋转立方织构含量上升,高斯织构含量较稳定。

关键词(KeyWords)： 无取向硅钢;冷却速度;织构
