| Abstract: | Thermodynamic calculation on the smelting slag of direct recycling of electric arc furnace stainless steelmaking dust was
presented. An induction furnace was used to simulate electric arc furnace smelting to recover the metals from the dust. The
elements of iron, chromium and nickel in the ingot and the components of metal oxides in the slag were analyzed. The thermodynamic
model for FeO-Cr2O3-MgO-SiO2 slag was set up and the active concentrations of substances in the slag at 1 550 °C were determined by thermodynamic calculation
according to the experimental data. The results show that the apparent equilibrium constant and quantitative distribution
of chromium between slag and steel are unstable and affected by the mass ratios of pellets to start iron and metal reducing
agent to the pellets. In order to get satisfactory chromium recovery from the direct recycling of electric arc furnace stainless
steelmaking dust, it is important to ensure the mass ratio of pellets to the steel below 0.20 and the mass ratio of metal
reducing agent to pellets over 0.18 in practical smelting runs.
