摘　　要：采用电解中型试样+激光粒度分析仪的方法,测定了钢中粒径为1～100μm夹杂物的尺寸分布,填补了粒径为20～80μm夹杂物尺寸测定的空白。发现IF钢粒径为1～100μm的夹杂物中SiO2类夹杂物所占比例较高,并且正常坯夹杂物中粒径大于30μm的夹杂物所占的比例可达4.25%,这对冷轧板的表面质量存在极大的威胁。The size distribution of inclusions between 1 to 100 μm in diameter was obtained by middle size sample elec- trolysis combined with laser grain size analyzer, which provided a method to measure the size of inclusions ranging from 20 to 80μm. It＇s observed that the major inclusions, of which size is from 1 to 100μm, are SiO2-type in IF steel. The content of inclusions larger than 30 μm is up to 4.25 %, which would be a significant potential threat to the surface quality of cold-rolled steel products.
