Abstract

In order to make full use of the chromium-bearing vanadium titanium magnetite with chromium, a new process of “direct reduction-electric furnace smelting separation” has been developed for recovering the iron, vanadium, titanium and chromium in recent years. In this paper, FactSage, one of the most frequently-used thermodynamic calculation software, was used to calculate the reduction degree of Fe, V and Cr with different nC/nO (mole ratio of carbon and oxygen). It was found that the suitable operating conditions of direct reduction process were nC/nO > 1.07 and T > 1473 K. In addition, the direct reduction experiment of Hongge vanadium titanium magnetite was carried out and the obtained samples after direct reduction were analyzed by XRD and chemical composition. The result shows that the metallization rate of carbon-containing pellet is nearly 90%.
