Abstract:

The usefulness of the water-cooled probe technique to experimentally study slag solidification and freeze lining formation in pyrometallurgical reactors is evaluated. With this technique a layer of solidified slag is formed on a water-cooled probe that is submerged into a liquid slag bath. The influence of the submergence time and the heat input is examined. The solidified layers are analyzed with light microscopy, electron microscopy, electron probe micro-analysis and X-ray diffraction. Thermodynamic software is used to interpret the solidification microstructure. The results demonstrate that the technique is useful to understand freeze lining formation.
