| Abstract: | In this paper, fluidizing pre-oxidized is studied for accelerating reduction rate of Da Bie Shan magnetite in two-stage smelting reduction. It is determined in the experiments that pre-oxidizied can accelerate reducting rate. It needs 60 minutes to obtain 70% reduction degree for the magnetite with 25% low oxidation degree, which satisfies fluidizing pre-reduction requirement for smelting reduction. |
