摘要：

The reduction rate of FeO by solid carbon in molten slags of two systems, FeO-CaO-SiO//2-MgO and FeO-CaO-SiO//2, has been determined by the method of measuring kinetic parameters: A combination of the initial concentration in the system with the rate of weight loss of the reductant in the reaction process was made. The reduction rate determined by this study is that of an apparent first-order reaction of the overall wt-% of FeO. The measured apparent activation energy is 222. 60 kJ/mol. Experimental results show that convection diffusion is the rate-controlling step in the reduction of molten FeO by solid carbon.
