Abstract
The kinetic behavior of reduction of chromite ore by liquid iron containing carbon and silicon has been investigated under various experimental conditions to clarify the reduction mechanism. It was found that the reduction rate of chromium ore by liquid Fe-C alloy was very slow. In addition, when carbon and silicon coexisted in the iron melt, silicon was found to preferentially oxidized to form silica, which favored for the formation of liquid slag and the rate of reduction was considerably accelerated. The similar effect was obtained by the addition of some fluxes, such as SiO2, Na2B4O7, CaO-SiO2, which also promoted the formation of a liquid slag and thus the reduction rate in the early stage also increased.
