为使还原条件与实际电弧炉生产相接近，在等温条件下对电弧炉粉尘球团的还原过程动力学进行了研究。电弧炉粉尘与还原剂碳和粘接剂石灰均匀混合后制粒，经干燥后将球团置于恒定温度的加热炉中，利用电子称定时对球团重量进行检测。金属还原率的计算中，考虑了球团的失重、铅和锌在高温下挥发。经研究，电弧炉粉尘的还原分为二个阶段，还原初期由化学反应控制而还原后期由扩散控制，并建立了每一阶段的还原动力学方程，确定了有关的动力学参数表观活化能和频率因子。
In order to make the reduction conditions close to the actual EAF production, kinetics of reduction process of EAF dust pellet was studied under isothermal conditions. EAF dust and reductant carbon and binder uniformly mixed lime granulation, after drying the pellet placed in a constant temperature furnace, the use of electronic scales to test the pellet weight. Calculation of the metal reduction rate, taking into account the weight loss of pellets, lead and zinc volatilize at high temperatures. After the study, the reduction of EAF dust is divided into two stages, the initial stage of reduction is controlled by chemical reaction and the later stage is controlled by diffusion, and the reduction kinetic equation of each stage is established, and the relative activation energy of kinetic parameters And frequency factor.
