摘要
本文探讨了利用二步熔融还原法流态化预还原宝钢纽曼山矿粉时影响还原速度的动力学规律，确定了最佳工艺参数，在此参数下，预还原可达到最佳的效果．
The dynamics pattern to effect the reduction vilocity is studied in this paper when Baogang Newman Hill iron ore concentrate is pre-reduction during fluidization in the two-staged smelting reduction process. the optimism technical parameters are defined.under these conditions better effect is obtained through prereduetion.
