摘要
针对典型牌号无取向硅钢,分析研究了N、 S、 Ti等杂质元素对无取向硅钢磁性能的影响。结合实际工艺生产经验,总结分析了高磁性能无取向硅钢所需超低S、超低N、超低Ti的冶炼工艺和关键控制技术。通过关键控制工艺的优化,可保证高磁性能硅钢片对应的S、 N、 Ti控制水平达到0.002 0%以下。
This study explored the influence of S, N, Ti and other impurity elements on the magnetic properties of non-oriented silicon steel. Base on the industrial production experience, the smelting process and key control technology of ultra-low S, ultra-low N and ultra-low Ti for nonoriented silicon steel with high magnetic properties are summarized and analyzed. By optimization of key control process, the control level of S, N and Ti for high magnetic silicon steel sheet can be guaranteed to be less than 0.0020%.
