Abstract

AbstractThe current work is an update on the equilibrium between a synthetic high titania slag and metallic iron at temperatures above the slag melting point. The experimental setup is essentially the same as previously shown in the literature, thus employing a cold crucible in a high frequency induction furnace. A new addition to the experimental setup is the temperature measurement by a spectropyrometer. The temperature measurements will give the liquidus temperature for the slags. This temperature shows a decreasing trend as the FeO content in the slag increases. 24 slags have been successfully produced with iron saturation with a FeO content ranging from 6 to 33 wt%. The slags show a clear trend and provide a solid foundation to the location of the slag‐metal equilibrium line in the investigated area. The experiments are in agreement with previously published experimental data but not with previously calculated results using thermodynamical software.
