摘　　要：安阳钢铁公司100 t交流竖式电弧炉于1999年11月投产,其变压器容量为60～72 MVA.冶炼时兑33%左右的铁水,竖炉预热废钢的温度达400～600 ℃,并采用氧油烧嘴和水冷碳氧枪操作和圆心炉底出钢(出钢量110 t)等操作技术使电弧炉电耗降至220 kWh/t,电弧炉作业率达92%,冶炼周期平均为41 min,年产钢量超过100万t,显著降低了生产成本.An 100t AC shaft are furnace with transformer rating capacity 60 ～ 72 MVA was put into production at Anyang Steel in November 1999. With adopted the operation technology such as charging about 33% hot metal, shaft preheating temperature of scrap between 400℃ and 600℃, oxygen-oil burner and water cooling oxygen jet operation and OBT tapping （taping amount 110t）, the electric power consumption of are furnace has decrease to 220kWh/t, the operation rate is up to 92%, average tap-to-tap time 41 min, the annual output over one million to obviously decrease production cost.
