The corrosion of refractory materials in pyrometallurgical operations by molten metal and/or slag is a major concern for furnace operators as refractory wear or failure inevitably results in reduced production efficiency and furnace shut-downs. Hence, the aim is to select adequate furnace linings for the individual process to provide homogenous wear and predictable refractory life for scheduled maintenance and high furnace availability. To understand the nature of the reactions involved in refractory corrosion, it is crucial to have an understanding of the chemical equilibria and the thermodynamics of the reactions
High-temperature interactions between refractory materials and molten slags were studied in the present investigation using hot-stage microscopy coupled with thermodynamic analysis, aiming to understand the corrosion mechanisms and draw implications for improving the refractory performance and lifetime.
Combining the results of the hot-stage microscopy study with the thermodynamic analysis using FactSageTM, a framework was developed for the refractory corrosion mechanisms.
