Abstract
Aiming at the direct production of Ti–Fe alloy, its direct electrowinning has been attempted in a CaF2–CaO–TiO2–FeO bath by using a direct-current electro-slag remelting unit. The experiments were carried out in the slag where the molar ratio of CaO to TiO2 was fixed as 1.5, and the influence of the molar ratio of FeO to TiO2 was mainly investigated. The experimental results proved that Ti–Fe alloy in liquid could be obtained at the limiting bath compositional range. At the molar ratio of FeO to TiO2 was 0.90, both the Ti content in the deposit and the cathodic current efficiency were the best under the conditions in this study; the Ti content reached about 50 wt%, and the cathodic current efficiency also did about 50% at best.
