The impurity content is an important index reflecting the quality of sponge titanium, especially Fe and Mn impurities. However, at present, only qualitative research has been conducted on the input of impurities, and no quantitative research has been conducted on the input and output of impurities. Therefore, based on the input-output model, this study analyzes the input and output of typical impurities in the magnesiothermic reduction-vacuum distillation process, product sorting process, and magnesium processing process, respectively. Quantitative characterization of the input and output of impurities in sponge titanium production. The results show that the Fe impurity is mainly input by the equipment, and the Mn impurity is mainly input from the raw materials. Determined the chemical reactions of impurities Fe and Mn during reduction, impurities of Fe and Mn exist in the product as the form of simple substance after the reaction.
Key words: sponge titanium / input-output / typical impurities / quantitative characterization
