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。

Abstract

An 100 t AC shaft are furnace with transformer rating capacity 60~ 72 MVA was put into production at An- yang 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 110 t)

the electric power consumption of arc furnace has decrease to 220 kWh/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.
