Rapid analysis of steelmaking slag by energy-dispersive X-ray fluorescence spectrometry

摘要

An X-ray fluorescence method using a semiconductor X-ray detector was investigated for rapid analysis of slag in steelmaking process. Metallic rectangular solid was dipt in molten slag layer, and slag thin piece grew on the solid. Because thisslag piece was rapidly solidified and was fiat, it could he directly analyzed by X-ray fluorescence method.Slag thin pieces obtained by large volume steel sampler were excellent as uniformity and representativity of slag component. These features gave excellent result for the determination of CaO, SiO{sub}2 ,Al{sub}2O{sub}3, Fe and MnO in steelmaking slag. Inthis method, the analysis time was shortened to 5 minutes. As the results, rapid and simple analysis of slag for steelmaking was established.
