摘要
本文通过对赤铁精矿粉流态化预还原试验，探讨了矿粉附碳中与附碳后的还原综合动力学问题，并建立了相应的宏观速率方程和动力学模型，为流态化预还原工艺提供了重要的操作依据．
The pre-reduction process of iron ore concentrate on a fluidization bed is studied in this paper.the reduction synthetic dynamics problems of ore among and after carbon-adheriny are researched the apparent velocity equation abd dynamics model are also set up, It provided the the important operation basis for the pre-reduction technics in fluidization.
