Abstract:In order to improve the properties of non-oriented electrical steel and optimize the production, the effect of different content of acid soluble aluminium on inclusions in non-oriented electrical steel was investigated by the method of SEM-EDS. The results show that when acid-soluble aluminium content in steel is 0.2%-0.4%, inclusions in the refining stage are Al2O3 with high melting point and globular MgO-Al2O3. While acid-soluble aluminium content in steel less than 0.005%, inclusions in the refining stage are Si-Al mixed manganese salts. The average size distribution of inclusion in each station is followed by a decreasing trend.
