摘要
Based on laser induced breakdown spectroscopy(LIBS) technique, the content of the main elements in the liquid steel of steel alloy can be detected in real time during melting process. In order to improve the detecting accuracy, the quantitative analysis method of laser induced breakdown spectroscopy(LIBS) for the melting alloy steels has been investigated. In this paper,the clustering method combined with the partial least squares method is applied in the metallurgical industry to determine the the element concentration of the steels. The experimental results show that the relative standard error is less than 1.316% and the average absolute error is 0.869%. The accuracy of the method is better than that of traditional partial least squares method, and the relative standard error of measurement is obviously reduced.
