本文采用以多段反应带模型为基础的三段两反应带还原模型分析了怀集磁铁矿球团(直径11.5mm,总铁68.5%,FeO 24.2%孔隙度0.028,还原温度850-1000℃)的氢还原。计算出的还原曲线与试验数据相吻合。
In this paper, a three-stage two-zone reaction zone model based on multistage reaction zone model was used to analyze the magnetic properties of Huaiji magnetite pellets (diameter 11.5mm, total iron 68.5%, FeO 24.2% porosity 0.028, reduction temperature 850-1000 ℃) Hydrogen reduction. The calculated reduction curve is consistent with the experimental data.
