Thermodynamics of Ti in liquid steels and slags was studied in order to establish a data base for the prediction of TiO_x and TiN formation in liquid steels.The interaction parameters between Ti and i(i = Cr,Ti,Al, Si,Ni,Mo,Nb,N,O) in liquid iron and the equilibrium constants for the formation of TiN and TiO_x in liquid iron were determined as a function of temperature.In view of high Ti yield during ladle treatment,thermodynamics of titanium oxides in ladle slags was studied as well.Activity coefficient and redox equilibrium of TiO_x in MgO saturated CaO-Al_2O_3 slag are also discussed by measuring the distribution ratio of Ti between slag and iron melts and the Ti~(3+)/Ti~(4+) ratio in slag at 1 873 K.
Thermodynamics of Ti in liquid steels and slags was studied in order to establish a data base for the prediction of TiO_x and TiN formation in liquid steels. The interaction parameters between Ti and i (i = Cr, Ti, Al, Si, Ni, Mo , Nb, N, O) in liquid iron and the equilibrium constants for the formation of TiN and TiO x in liquid iron were determined as a function of temperature. View of high Ti yield during ladle treatment, thermodynamics of titanium oxides in ladle slags was as well. Activity coefficient and redox equilibrium of TiO_x in MgO saturated CaO-Al_2O_3 slag are also discussed by measuring the distribution ratio of Ti between slag and iron melts and the Ti ~ (3 +) / Ti ~ (4+) ratio in slag at 1 873 K.
