X-ray fluorescence spectrometry determination of open-hearth furnace slag by pressed powder briquetting

Chemical composition of open-hearth furnace slag isimportant for the metal and casting quality. The chemicalcomponents of slag need to be analyzed precisely andaccurately.For a long time the composition determination of slag ismade chemically, which involves complicated processes,long analytical cycle, high cost and tedious work. A greatmany successful applications of ores analysis by x-rayfluorescence spectrometry (XRF) have been reported1-4].Powder-fused wafer is a sampling method used in…

X-ray fluorescence spectrometry determination of open-hearth furnace slag by pressed powder briquetting

A rapid analysis method of determining content of eight compounds of open-hearth furnace slag was developed using X-ray fluorescence spectrometry and pressed powder briquettes. Matrix effect was corrected using theoretical alpha coefficient. Grains-size effect was eliminated by optimized sample preparation technique parameters. Mineral effect was corrected with standard curve of specially made standard samples. The analysis results of TiO2, TFe, SiO2, MgO, Al2O3, CaO, MnO and P2O5 in slag samples showed that both precision and accuracy are comparable with that of chemical method.
