Abstract

A pilot plant for comprehensive utilization of the vanadium titanium magnetite resources was constructedin Pangang Group, and the plant applies direction reduction in the rotary hearth furnace (RHF)-melting deep reduction in electric arc furnace (EAF) as the main process. Through constant experimental research, optimization and improvement many technical problems have been solved such as parameters controlling of the RHF, recovering vanadium slag from the hot metal with low carbon and high silicon content, recovering V2O5 from vanadium slag with high SiO2 content, producing titanium pigment from the titanium slag, etc. This process is feasible and the recovery rate of Fe, V, and Ti reach to 89%, 45%, and 72% respectively. On the other hand, there exist some problems that have not been solved yet including short life span of the refractory of the EAF, low recovery rate of the thermal energy and so on. Under current conditions, deep researches are need to be done continuously and study on the shaft furnace should be carried out to make useful supplement for the RHF direct reduction process.
