The amount,composition and size of inclusions in finished specimens of steady and unsteady casted non-oriented electric steel slabs are analyzed by electrolysis extraction of inclusions and SEM-EDS and the effect of inclusions on iron loss of coil is discussed.The results show that the main inclusions are AlN,MnS and Cu2S in both of these slabs with a small amount of inclusions in the first and final slabs.The amount of inclusions under 0.5 μm is about 15,000,000 per cubic millimeter and the amounts of inclusions with size range between 0.5 μm and 5.0 μm are 1,230,000 per cubic milimeter and 750,000 per cubic milimeter in unsteady and steady casted non-oriented electric steel slabs respectively.This is the main reason for the different iron loss between these corresponding finished products under steady and unsteady casting processes with the same casting heat.
