Abstract

For a number of reduction technologies of ferrous production the period, during which the first ferrous slag phase coexists with a hard metallic phase of newly reduced iron, is a characteristic feature. The interaction of these phases highly influences the processes of metal saturation by carbon and other impurities, as well as processes of metal and slag separation into independent phases. Surface wettability of hard iron with the liquid ferrous slags of FeO-CaO-SiO2 and FeO-Al2O3-SiO2 systems at temperature 1100-1300 °С was investigated experimentally.
