Title:
COMPONENT ANALYSIS METHOD OF PARTICULAR IRON-MAKING MATERIAL AND COMPONENT ANALYSIS DEVICE OF PARTICULAR IRON-MAKING MATERIAL
Document Type and Number:
Japanese Patent JP2023128276
Kind Code:
A
Abstract:
To accurately measure a component composition of a particular iron-making material by using a laser-induced breakdown emission spectral analysis method.SOLUTION: A component analysis method of a particular iron-making material according to the present invention comprises: a pre-treatment process of emitting a laser beam having the laser power density of 2-20 GW/cm2 to the particular iron-making material; and a component analysis process of performing component analysis by means of laser-induced breakdown emission spectral analysis by emitting the laser beam for analysis to at least a portion of a spot irradiated with the laser beam in the pre-treatment process.SELECTED DRAWING: Figure 1A
