This paper deals with an investigation of a chip-briquette method for eliminating the effect of microst ructure and segregation in the emission spectroscopic analysis of low carbon steel products. In the method, when the chips for analysis are obtained from rolled steel product by sawing, its microstructure, having been passed through any process of heat treatment, are transformed intensely into similar fine grains. And by mixing of chips before briquetting for analysis, sample uniformity at the size of analytical spot is made better. Consequently, it is possible to eliminate their effects in the analysis. The analytical results of various low carbon steel products are improved.
