Abstract

In this paper, internal heat transfer process of vanadium titano-magnetite concentrate carbon-containing pellets was analyzed in direct reduction at different temperatures. The thermal conductivity of vanadium-titanium magnetite carbon-containing pellets at different temperatures were determined under the condition of optimal process parameters taken from previous works. XRD was used to examine the phases of various products at different temperatures in direct reduction. Experimental results revealed that change in thermal conductivity of vanadium titano-magnetite concentrate was roughly the same as the common iron ore concentrate. The measured values of the thermal conductivity were consistent with the changing trend of the theoretical thermal conductivity. The thermal conductivity change within 0.06~0.12 W/m in the temperature range of 300 -1150 . The thermal conductivity increase very rapidly when temperature exceeds 1000 .
