FeMn-alloys are produced by transforming ore and carbon materials into FeMn and slag at high temperatures in a furnace. Entrainment of FeMn in slag during tapping reduces the yield. Entrainment and subsequent separation are strongly influenced by slag-metal interfacial properties. In the current work, interfacial properties, including the contact angle, in the FeMn-slag graphite system have been investigated using the sessile drop technique at temperatures above 1300 °C. Two experimental configurations are proposed: (a) slag and metal placed beside each other on graphite; and (b) slag placed on top of the metal layer, which is in contact with graphite. Results demonstrate that the contact angle between slag and metal is 55-60° at temperatures from 1310 to 1350 °C and slag-metal weight ratio around 0,25. In addition, wetting properties are considerably influenced by the variation of slag-metal weight ratio in the range from 0,25 to 1,50 and only marginally by temperature.
