| titleOfInvention | Method for measuring particle size distribution of alumina inclusions in steel |
| abstract | Provided is a method for measuring the particle size distribution of alumina inclusions dispersed in a steel material faster and more accurately than before by using a spark discharge emission spectroscopic analysis method. The light emission by spark discharge of a steel material is spectroscopically measured, the intrinsic spectral line intensities of Fe and Al are measured for each discharge, and their minimum values are subtracted from the Fe intensity and Al intensity in each discharge, respectively. After the background correction, the Al / Fe intensity ratio Mi, its statistical median Mc, and the ratio R between the Al intensity and the Al evaporation weight are obtained, and in the Al intensity: Fe intensity scatter diagram for each discharge. The straight line L passing through the origin and Mc is obtained, the difference between the Al intensity located above it and the Al intensity on the straight line L is obtained, and this difference is divided by R to calculate the aluminum evaporation weight in the discharge. Then, the volume and particle size of the alumina inclusions are calculated in terms of the alumina evaporation weight. [Selection] Figure 1 |
