摘要: 研究了Ti、S元素对高牌号无取向硅钢热力学参数平衡态的第二相析出物的影响,并结合工业生产中实例样品进行分析。研究结果表明,平衡态下,随着Ti、S含量的增加,Ti(C,N)、MnS的开始析出温度及稳定析出量均增加;工业生产中,常化板的高Ti低S的样品两种析出物的平均尺寸和面密度均大于低Ti高S的样品,而成品板析出物的平均尺寸和面密度均小于低Ti高S的样品。

Abstract: The Effects of the elements of Ti and S on the second phase precipitates of high grade non-oriented silicon steels in equilibrium state and mass production have been studied. The results showed that the precipitation starting temperature and stable precipitation amount of Ti(C,N) and MnS were both increased as the increase of the contents of Ti and S in equilibrium state.While in industrial production, the average sizes and area densities of the two precipitates in normalized plate’s samples with high Ti and low S contents were both higher than the samples with low Ti and high S contents, but in finished plate, it can be seen that the two precipitates’ average sizes and area densities in the samples with high Ti and low S contents were both lower than the samples with low Ti and high S contents.
