Phase and chemical equilibria in the melt (Fe–Si–C)–Slag (CaO–Al2O3–SiO2)–Gas (O2–SiO–CO) system

The equilibrium compositions of high-silicon metallic melts coexisting with CaO–Al 2 O 3 –SiO 2 slag are determined. The dependence of the activity a of silicon in ferrosilicon melts is formulated as activity isolines on the Fe–Si phase diagram. The dependence of log on x Si and T is determined at 1...
