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

关键词: 无取向硅钢, 冷轧, 断带, 边裂

Abstract: 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.

Key words: non-oriented silicon steel, cold rolling, broken belt, edge crack
