During the refining process,the transformation of non-metallic inclusions in non-oriented silicon steel produced by the process of KR-BOF-RH-ASP is analyzed using the methods of SEM-EDS and main sources of non-metallic inclusions are identified in this paper.The results show that the inclusions after RH process are mainly Al2O3 and sulfides at l μm;then in the tundish,the amount of Al2O3 in the sample remarkably decreases while compound inclusions containing CaS,MgO-Al2O3 and sulfides increase to a certain extent,sizes of inclusions in different working sections are mainly at 0.5~3 μm.
