Effect of Ilmenite Component and AIR on Element Distribution of Titanium Slag Smelted by DC Arc Furnace

摘要：

　　Based on chemical eqnilibrium calculation method in multi-phase, multi-compo nent system, effects of ilmenite component (TiO2, Fe2O3, FeO) and AIR on element distribution of ti tanium slag smelted by DC arc furnace were stud led.The calculated results agree well with the exper imental results.With increasing amount of TiO2 and FeO in iimenite, the amount of C for minority de ment and for TiO2 and FeO reduction increase, the mass fraction of total TiO2 and Ti2O3 in slag in crease, while the mass fraction of FeO in slag de creases.However, the effect of Fe2O3 content in il menite on the slag composition is opposite.With in creasing of TiO2 in ilmenite from 42 % to 50 %, the mass fraction of TiO2 in slag increases by 7.9 %.However, with increasing of Fe2O3 in ilmenite from 12 % to 20 %, the mass fraction of FeO in slag in creases by 8.94 %.Moreover, with increasing of AIR from 120kgt-1 to 134kgt-1, the mass fraction of TiO2 in slag increases from 83.8 % to 91.77 %, FeO mass fraction decreases from 14.7 % to 6.25 %.The sensitivity of other components on the total TiO2 in slag is displayed as: SiO2 > MgO > Al203 >CaO.Ilmenite component and AIR can be con trolled to achieve selective reduction of oxides in the melt.Study on allocation behavior of elements dur ing titanium slag smelting reduction process can help control the process, improve the slag taste.
