采用扫描电镜、场发射扫描电镜、能谱仪等对50SW1300冷轧无取向硅钢中的夹杂物分不同尺寸区间进行数量统计,利用主成分回归分析法,即数据的标准化处理—主成分分析—回归分析—标准化的变量还原成原始变量—确定显著影响因素,综合分析夹杂物总量及各尺寸区间的夹杂物数量对无取向硅钢磁性能的影响。结果表明:主成分回归分析能够从夹杂物尺寸区间及数量的多个影响因素中提取主要的因素,定量研究其对磁性能的影响。分析表明,显著影响无取向硅钢铁损的夹杂物为100~500nm的AlN、AlN+MnS、MnS、Al2O3、AlN+Al2O3,而劣化磁感最明显的夹杂物尺寸区间为100~200nm。 Different size intervals of inclusions in cold rolled non-oriented silicon steel 50SW1300 were counted by scanning electron microscope(SEM),field emission scanning electron microscope(FESEM)and energy disperse spectroscopy(EDS).With principal component regression method:standardization for experimental data,principal component analysis,regression analysis,transform standardized variables into original variables,determination of significant factor,effects of the total number of inclusions and the... 

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. 

就冷轧硅钢废水处理生产中面临的主要问题进行分析,从技术角度及运行管理角度提出工艺优化升级改进措施及应对策略;同时从后续深度处理,逐步实现零排放目标的角度进行探讨,为冷轧硅钢废水减量化、出路乃至废水零排放提供一些思路。 The main problems in the wastewater treatment process of cold-rolled silicon steel lines are analyzed and process upgrading measures and optimization strategy are put forward from both technical and management views.At the same time,downstream deep treatment to gradually achieve the target of zero discharge is discussed,to provide some ideas for reduction or even zero discharge of wastewater from cold-rolled silicon steel lines.
