摘要
攀成钢70 t高阻抗超高功率偏心底电弧炉的炉料为20%铁水+80%生铁-废钢。在电弧炉的炉壁上安有3支RCB集束喷枪装置和炉门两侧墙上安有两处喷碳粉枪。冶炼实践表明,吹氧脱碳速度达0.08%～0.012%C/min,冶炼电耗为310.86 kWh/t_钢,电极消耗1.67 kg/t_钢,氧气消耗46.7 m^3/t_钢,冶炼周期56 min。
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^3/t steel, and the tap to tap time was 56 min.
