Calculation of equilibrium in the system «metal – slag» during steelmaking in electric arc furnace

Abstract

A method for simultaneous solution of equations of material balance of the process and mathematical description of the equilibrium with the definition of active ingredients of slag as the phase with itinerant electrons is developed. To find solutions in the method of iterations there tested steepest descent algorithms and random search steps. The proposed approach provides a preliminary assessment of the results of the process steps with the process model, which will allow the staff of electric arc furnace to make right decisions. The use of modern computer technology to support management decision-making process eliminates the computational constraints and performs the calculation of process parameters with the help of developed model No.6 — 2016 Metallurgical and Mining Industry 9 Automatization
