Resumo
THE CHANGES IN METAL AND SLAG HAPPENING FROM THE ELECTRIC ARC FURNACE (EAF) TAPPING INTO THE LADLE FURNACE (LF) PROCESS ARE CRITICAL FOR THE EFFICIENT OPERATION OF A MELT SHOP. IN THIS WORK, WE PERFORM A FIRST ATTEMPT AT USING A COMPUTATIONAL THERMODYNAMICS KINETIC EFFECTIVE EQUILIBRIUM REACTION ZONE (EERZ) MODEL TO DESCRIBE THE COMPLEX CHANGES HAPPENING FROM TAPPING UNTIL ARRIVAL AT THE LF. THE KINETIC CONSTANTS OF THE MODEL ARE INVESTIGATING, LOOKING AT THEIR EFFECTS IN MEASURABLE QUANTITIES SUCH AS SOLUBLE AND TOTAL OXYGEN, SLAG COMPOSITION AND AMOUNT OF SLAG. FURTHERMORE, THE EVOLUTION OF THE OXYGEN POTENTIAL IN SLAG AND METAL IN INVESTIGATED. TWO PROCESS CHANGES ARE INVESTIGATED TO EVALUATE THEIR EFFECT IN THE PROCESS. THE MODEL IS SHOWN TO BE VERY PROMISING IN HELPING TO PREDICT THE EFFECT OF CHANGES IN PROCESS PARAMETERS AND THE ADJUSTMENT OF PARAMETERS TO ACTUAL INDUSTRIAL RESULTS IS THE NEXT PROPOSED STAGE OF MODEL DEVELOPMENT
