摘要：

Thermodynamic reaction of electric steel smelting furnace gas cleaning dust components with solid carbon using a TERRA program for thermodynamic calculation of arbitrary heterogeneous system phase composition is studied. Data are provided for the standard change in Gibbs energy for reduction reactions of metals within dust composition (supposedly in the form of oxides), on whose basis metals are determined that may be reduced by carbon up to 1200A degrees C. The amount of carbon required for reducing these metals is calculated. The equilibrium composition is determined for a steel-smelting dust - solid carbon system in the temperature range 27-1227A degrees C at atmospheric pressure. The optimum amount of carbon for processing steel-smelting dust is determined.
