THERMODYNAMIC SIMULATION OF IRON REDUCTION FROM LIQUID SLAG

https://doi.org/10.17073/0368-0797-2014-3-64-69

Abstract

Thermodynamic simulation of iron reduction from liquid slag by carbon was carried out in the context of smelting reduction technologies of iron production. It is shown that iron reduction from liquid slag is thermodynamically possible only in case of the absolute domination of bivalent iron (FeO). This stage is always preceded by reduction of trivalent iron (Fe2O3) dissolved in slag up to bivalent iron. The formation of low-carbon iron drops at 1450 °C is possible with the residual concentration 0.5 – 0.2 % FeO in slag.
