Charge of 70 t high impedance UHP EBT electric arc furnace at Chengdu Iron and Steel
Pansteel is 20% hot metal+80% pig iron-scrap. Three RCB coherent oxygen lances are installed at wall of furnace and two lances for coal powder injection are installed at wall of both side of furnace door. Steelmaking practice showed that the decarburization rate by blowing oxygen was 0.08%~0.012% C/min
the electric power consumption was 310.86 kWh/t steel with electrode consumption 1.67 kg/t steel and oxygen consumption 46.7 m
