Abstract

The complicated reduction behaviors of iron, vanadium and titanium oxides must be accurately controlled for the successful smelting of vanadium titanomagnetite. The aim of this study is to investigate the effects of the binary basicity, MgO content, smelting temperature, duration and reductants on the reduction of iron, vanadium and titanium oxides during the electric furnace smelting of vanadium titanomagnetite metallized pellets. The results demonstrate that the recovery ratios of both iron and vanadium increase as the binary basicity increases from 0.9 to 1.2, whereas the reduction of titanium oxides is mitigated when the basicity is maintained at 1.1. Compared to its weak effect on the recovery ratio of iron, increasing MgO content improves the vanadium recovery ratio. A low content of titanium in molten iron is obtained when the MgO content in the slag is lower than 11%, whereas the titanium content in the molten iron increases as the MgO content increases further. Moreover, the iron and vanadium recovery ratios, and the Ti content in the molten iron, increase with increasing smelting temperature, duration and reductant content.
