Ferromanganese alloys are main sources of manganese for various grades of steels. Recent development of high manganese steels prompted the research on the production of high purity ferromanganese alloys. Nitrogen control in ferromanganese alloys became also important for the production of low nitrogen containing high manganese steels. However, studies on nitrogen control in ferromanganese alloys are very limited. In the present study, the nitrogen solubility in Mn-Si, Mn-Fe-Si, Mn-Si-C and Mn-Fe-Si-C melts was measured by the gas-liquid metal equilibration technique in the temperature range from 1673 to 1773 K. The addition of iron, silicon and carbon in Mn-rich melts significantly decrease the nitrogen solubility. The experimental results were thermodynamically analyzed by Wagner’s formalism to determine the interaction parameters of Fe, Si and C on nitrogen in liquid manganese alloys. The present results can be used to predict the nitrogen content during refining of ferromanganese alloys.
