Abstract��The non-metallic inclusions (NMI) in clean steel�� which are mainly generated in steelmaking process�� have great influence on the macro-properties of steels. The analysis of NMI can create the ��bridge�� between steelmaking process and the property of steels�� and provide reference for the process control and R & D of clean steel products. The characterization technique of NMI was reviewed. It was classified into 35 types according to the sample preparation method. The automatic analysis of NMI with size of 1-20 ��m by scanning electronic microscope (SEM) had become a hot topic recently. The characterization methods of NMI were briefly introduced. The concrete practices indicated that the measurement results could reflect the steelmaking process system (total oxygen control)�� and they were fully corresponded to the final macro-property of steels (drawing breaking rate). This method provided reference for other researches at home and abroad.
