Thermal effects on wear and material degradation of slag pots operating in steel production

This study addresses thermal effects on wear, failure and degradation mechanisms present at slag pots. Additionally, attempts for specific solutions will be proposed. Results indicate that thermal shocks and oxidation lead to material degradation, which alongside the thermally induced deformation of the pot shape reduce the overall lifetime. Layers of solidified slag inside the pots further cause severe abrasive wear on the inner pot walls during the discharging procedure.
