Phase equilibria of Fe-S-C ternary melts have been studied to obtain fundamental knowledge on copper removal from liquid iron by FeS flux. Measurements were made to clarify the solubility of carbon and miscibility gap between iron and FeS melts at carbon saturation or unsaturation 1473 to 1873 K. In order to determine the interaction parameter in the Fe-C binary system, activity of iron in liquid alloys was measured by the distribution of iron between liquid iron and silver. It is concluded that interstitial model is applicable to express thermodynamic relations in this system. By this model, phase diagram and iso-activity contour of constituents were calculated.
