Slag basicity ratios
WebThe paper presents a balance model of the blast-furnace process improved by the researchers from the Ural Federal University and Magnitogorsk Iron and Steel Works. It generally represents a system of deterministic dependencies characterizing the WebDuring current study, effect of temperature, FeO, CaO, SiO2 content and basicity ratio B2 on slag’s electrical conductivity was studied experimentally. It was found that, electrical conductivity increases with increasing temperature, %FeO, %CaO and basicity B2. On the other hand electrical conductivity was decreased with increasing SiO2 content.
