| Abstract: | The electric power and oxygen consumption per ton steel, tap to tap time in 100 t AC EAF steelmaking process of 1^st branch of Xingcheng Iron and Steel Co. Ltd. , were studied. When 70% hot metal charging process was adopted, the tap-to-tap time reduced to 45 min and the electric power and oxygen consumption can reach 98. 7 kW ·h/t, 48. 5 m^3/t, respectively, by increasing the oxygen supply intensity for the EAF to 1.25 m^3 /（t · min） and improving the efficiency of oxygen and operational processes. |
