In this study, thermodynamic analysis of an EAF was made to reduce solid wastes and energy consumptions. Then, the slag formation, quicklime consumption and daily energy consumption of the EAF were optimised for different basicity ratios at constant silicium ratios (1.42%). Finally, the system is re-optimised for varying silicium ratios at constant basicity ratio (1.87). As a result of the study, it was seen that the energy consumption was reduced by about 153.26 GJ per day and the mass efficiency of the system was increased from 92.60% to 95.33%. This energy saving is equal to 1,987,016.11 kWh, which is equivalent to the nearly 1,152 tones CO2 reduction per day.
