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.
