Preparation of V–Ti–Fe master alloys by metallothermic reduction method
چکیده انگلیسی

V–Ti–Fe master alloys were prepared by metallothermic reduction method, and the influences of the mass ratio of V2O5 to TiO2, Al and Al–Mg alloy addition amounts on the metal recovery rates and alloy compositions were investigated. The results show that appropriate technological parameters are: the mass ratio of V2O5 to TiO2 is 0.5:1, Al addition represents 95% of the theoretical value, and the Al–Mg alloy addition amount is one third that of the Al addition. The results from energy spectrum analysis show that V and Fe distribute uniformly in the prepared alloy, while the segregation for Ti, i.e. Ti-rich phase is detected. A spray refining process was carried out to reduce the impurity contents of Al and O in the prepared alloys. The Al content drops from 4.27% to 1.86%, and the O content drops from 2.10% to 0.91% after the refining process.
