在氮气气氛和１０５０～１３００℃温度范围内，采用化学分析方法研究了还原温度、过量碳及煤粉粒度对含锌铅粉尘配碳球团中氧化铁还原速率的影响．结果表明：还原温度对氧化铁还原速度有显著影响，过量碳和煤粉粒度对还原速率没有影响．在不同还原程度和还原温度下，得出了氧化铁还原的表观活化能，由活化能结果和还原动力学模型对实验结果进行分析，确定了氧化铁在不同还原程度和还原温度下的还原限制性环节．
The effect of reducing temperature, excess carbon and coal particle size on the reduction rate of iron oxide in the lead-bearing lead-dust with carbon pellets was studied by chemical analysis in the nitrogen atmosphere and the temperature range of 1050 ~ 1300 ℃. The results show that the reduction temperature has a significant effect on the reduction rate of iron oxide, and the excess carbon and coal particle size have no effect on the reduction rate. The apparent activation energy of iron oxide reduction was obtained at different reduction degree and reduction temperature. The experimental results were analyzed by the activation energy results and the reduction kinetic model, and the reduction of iron oxide at different reduction degree and reduction temperature was confirmed Restrictive links.
