热轧原料断面轮廓对冷轧硅钢尺寸精度的影响分析
根据现场实际的生产控制情况,指出了热轧原料断面轮廓缺陷以一定的比列遗传给了冷轧带钢,分析了不同热轧原料断面轮廓对冷轧电工钢尺寸精度的具体影响,提出了相应的规律。并阐明了严格控制热轧原料断面轮廓形貌,对保证冷轧电工钢尺寸精度具有重大意义,对于中国现行的冷轧电工钢生产具有指导意义。 Based on the actual situation of production control,it was pointed out that the section profile defects of hot-rolled raw materials were geneticed to the cold-rolled strip.The specific impact analysis for the profile of different hot-rolled raw materials to the dimensional accuracy of cold-rolled silicon steel was analyzed.As a result, the corresponding orderliness are given;And the strict control to section profile of the hot-rolled material is of great significance to ensure the dimensional ac...
无取向电工钢中夹杂物的分析
对无取向电工钢中的夹杂进行了系统的分析。利用小样电解,采取不同电解液,不同的分离方法对无取向电工钢中稳定和不稳定夹杂物进行了提取、分离和收集。利用扫描电镜(SEM)、X-射线衍射、ICP等对电解分离收集的夹杂物进行了定性和定量分析。 The inclusion analysis of the non-oriented electrical steel has been investigated.By using small sample electrolytic analysis,with different electrolytes and different separation ways,the stable inclusions and unstable inclusions was drew,separated,and collected.With utilizing the methods of SEM,X-ray and ICP,the qualitative and quantitative analysis of inclusions in the non-oriented electrical steel was obtained.
