This article presents the results of thermodynamic modeling of the process of obtaining chromium-manganese ligature from ferro-manganese ore and dust from crushing ferrosilicochrome (FeSiCr). The calculations were performed using the HSC Chemistry software package, where dust from crushing FeSiCr was used as a reducing agent. The analysis was performed by varying the reducing agent dust FeSiCr from 10 to 100 kg in increments of 10 kg per 100 kg of ferro-manganese ore, at temperatures of 1400°C, 1600°C and 1800°C. The mechanism of combined metallothermic reduction of chromium (Cr), manganese (Mn), and iron (Fe) was studied in a multicomponent Fe-Cr-Mn-Si-Al-Ca-Mg-O system. Based on thermodynamic data, it was found that the optimal consumption of reducing agent is 50 kg per 100 kg of ore, and the most effective melting temperature is 1600°C, at which the best yield of chromium-manganese ligature is achieved. Additionally, laboratory tests were conducted under specific conditions, resulting in experimental samples of the ligature with the following chemical composition, %: Fe - 28.39, Cr - 16.58, Mn - 32.55, Si - 3.56.
