摘要：

The kinetic equation for the calculation of the reduction rate, which takes into account the physicochemical properties of contacting phases, is derived under the assumption of the electrochemical nature of interaction between the reducing gas (CO) and the oxide melt. Satisfactory agreement of calculated and experimental data is shown by the example of the interaction of the oxide melt of the CaO-SiO2-Al2O3 system containing up to 6.0 wt % Me (n) O (m) (NiO, CoO, Cu2O) blown by the gas phase with partial pressure P (CO) = (0.4-5.0) x 10(2) MPa at T = 1623 K.
