The increased intensity of the Electric Arc Furnace (EAF) steelmaking process has resulted in corresponding increases in energy losses. The reduction of chemical energy losses, by the injection of targeted oxygen, has the potential to become an enormous advantage in today's highly competitive steel industry. A variety of methods have been used for the addition of this supplemental oxygen, including auxiliary lances, oxygen injectors and existing side wall burners.; In this study the ratio of natural gas to oxygen, flowing through the existing side wall burners, was modified in order to increase the amount of free oxygen flow to the EAF at Co-Steel Lasco. Decreases of 4.0% with respect to Specific Electrical Energy Consumption, 42.7% with respect to Specific Natural Gas Consumption, 5.0% with respect to Power on Time, and 4.5% with respect to Tap to Tap Time were observed.
