Analysis of blast furnace slag by the pressed powder method

AppNote XRF1025: blast furnace slag by the pressed powder method


The blast furnace slag is formed when iron ore or iron pellet, coke and flux are melted in a blast furnace of iron foundry. The rapid chemical analysis of blast furnace slag is important task to control a blast furnace. X-ray fluorescence spectrometers are the most common analysis tools to analyze powder samples in iron and steel making process. This application note describes blast furnace slag analysis using ZSX PrimusIII+. The certified reference materials of the blast furnace slag which were provided by NCS (China national analysis center), JSS (Japan) and CSMU (Czech) were used to establish the calibration. The well-dried (2 hours at 105 °C) samples were ground using a grinding mill with a WC container for 2 minutes and then were pressed under the pressure 10 tons into 32 mm diameter PVC rings. Binder was not used.
