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 this slag piece was rapidly solidified and was flat, it could be 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_2, Al_2O_3, Fe and MnO in steelmaking slag. In this method, the analysis time was shortened to 5 minutes. As the results, rapid and simple analysis of slag for steelmaking was established.
