Résumé
The addition of nitrogen (N) to low-manganese (Mn) stainless steel significantly enhances its properties. However, producing high-N steel presents challenges, including N volatilization and casting system clogging. A strong foundation in thermodynamics is critical for understanding the direction and extent of chemical reactions under varying conditions. Building on thermodynamics, reaction kinetics provide insight into deviations from equilibrium. Experimental approaches, whether at the laboratory or pilot scale, are often time-intensive and costly. Computational thermodynamics offers an efficient alternative to address complex chemical reactions and interactions, particularly in high-temperature processes involving multicomponent systems and various operational parameters, where equilibrium is either local or global. This study applies computational thermodynamics to address challenges in producing high-N, low-Mn stainless steel in a scrap-based electric arc furnace route. It investigates the FeMnN addition to steel melt and explores potential causes of clogging in the nozzle and slide gate system during casting. Industrial measurements are incorporated to ensure the validity of the computational predictions.
