Abstract:With optimizing charging structure- using hot metal charging technology; intensifying oxygen supply by coherent oxygen lance technique; material flow sheet revamping by intensifying secondary refining and increasing concasting production capability,the annual steel output of a 60 t AC furnace and a 60 t DC furnace increased from before revamping 254500t to 873400 t,tap-to-tap time decreased from 107 min to71 min,electric power consumption decreased from 547 kWh/t to 213 kWh/t,coefficient of utilization of transformer increased from 3142 t(MVA ·a)to 10783 t/(MVA ·a)to get a available steelmaking process at Daye Special Steel and obtain better economic and technology effect.
Keywords:60 t EAF   High Efficient   Hot Metal Charging   Intensifying Oxygen Supply
