Abstract:The threshold setting method for abnormal signals of inclusion elements in automobile beam steel plate as well as the correlation relationship of signal frequency and intensity to inclusion content and size were investigated by original position statistic distribution analysis combined with chemical analysis, scanning electron microscope and energy spectrum analysis method. The original position statistic distribution analysis mathematical models have been discussed in detail for the analysis of total content and size distribution of Al inclusions in beam steel. The proposed methods have been applied to the content and size determination of Al inclusions from different part in frame steel. The distribution ratios of different type of inclusions in different size distribution section have been obtained. The calculated results by the proposed method have good coincidence with the value obtained by scanning electron microscope method and chemical method.
