摘要 本文定义了还原反应速率的计算式,依据矿石失重实验数据可计算反应速率的大小及其变化关系,可分析矿石还原过程速率的限制性环节。 The reduction rate of iron ores was redefined in this paper. According to this definition,the reduction rate and its variation with time can be caculated from the weight loss in reduction test. The controlling step of reduction rate can be determined too.
