Computational thermodynamics is a powerful tool widely applied in materials science, e.g. for alloy design. Thermodynamic databases developed through the CALPHAD approach usually give reasonable predictions of thermodynamic properties as well as the phase equilibria of corresponding multi-component systems.
A thermodynamic database, TCOX, has been developed for calculating thermochemical interaction between liquid steel and slag. With the TCOX database an attempt is made to develop an internally consistent database for oxygen-containing systems. Today the TCOX database includes the major alloying elements in steels as well as the important slag elements.
Additionally, a graphical interface for steel/slag calculations that is easy to use and suitable for the steel industry has been developed. Such an interface, together with the TCOX database, is a powerful tool for controlling complex metallurgical processes, for example desulphurization, dephosphorization or ladle refining, and in the development of new steel grades.
