摘要
无取向硅钢作为驱动电机和电机铁心的关键材料,厚度薄,Si、Al含量高,脆性大,冷轧生产中边部开裂严重,严重影响成材率。根据无取向硅钢成分及工艺特征,分析并总结国内外对无取向硅钢冷轧边裂产生原因,提出今后还需进一步研究和探索的方向。
Non-oriented silicon steel,as a key material for driving motors and motor cores,has a thin thickness,high Si and Al content,high brittleness,and severe edge cracking during cold rolling production,which seriously affects the yield rate.Based on the composition and process characteristics of non-oriented silicon steel,this article analyzes and summarizes the research on the causes of edge cracking in cold rolling of non-oriented silicon steel at home and abroad,and proposes directions for further research and exploration in the future.
