合金元素及常化工艺对冷轧无取向硅钢性能的影响

摘要

The research studied the effects of different alloying elements and normalizing process on the magnetic properties of cold rolled non‐oriented silicon steel .The results show that with the increase of Nb content ,the grow th of grains is inhibited during the annealing process ,and the magnetic properties also deteriorate .Adding a certain amount of Cr will decrease the product iron loss ,but normalizing tempera‐ture should not be too high .%研究不同合金元素及不同常化工艺对冷轧无取向硅钢磁性能的影响。结果表明，在本实验条件下，随着Nb元素含量的增加，会抑制退火过程中晶粒长大，恶化磁性能；添加一定量的Cr ，会改善成品铁损，但此时常化温度不宜过高。
