Thermodynamics of Carbon in liquid Mn-Fe-Si-C system
Thermodynamics of C in liquid ferromanganese alloys containing Fe,Si and C in a wide range of composition is very important to control C content in refining process.In the present study,the C solubility in Mn-Fe-Si-C melts was measured as functions of melt composition and temperature.The critical C and Si contents in Mn-Si-C melt for the co-saturation of graphite and β-SiC at which the composition can be used as the boundary condition for the calculation of the activity coefficient of carbon were also determined.Using the unified interaction parameter formalism (UIPF) and the experimental results,the activity coefficient of carbon at infinite dilution,γ°C and the interaction parameters among C,Si and Fe in Mn-Fe-Si-C alloy melts were determined.The model could successfully describe the thermodynamic property of C for a wide range of composition and could predict the C content in ferromanganese melts at specified refining conditions.
