Abstract：For non-oriented silicon steel 50W800 with RH process， there were plentiful inclusions， researchers employed SEM-EDS method to analyze the size， quantity and type of inclusions， and detected the constituents of slag. Results showed that Ar blowing could get rid of 39.11% inclusions， and the total area of inclusions reduced 2 406.94 μm2 from RH to tundish. The majority of inclusions were Al2O3 sized between 1-4 μm， and there existed a small amount of AlN?Al2O3 and CaO-Al2O3-MgO compound inclusions. Slag owned an excellent capability to absorb the inclusions， but the modification effect was not evident.
