| Abstract: | According to the electrical operation and steelmaking theoryof EAF, an improved power input procedure of 70 t high impedance EAFin Nanjinng Iron and Steel Corp. Ltd. was studied. The investigation method, process and result for use of power supply of high impedance EAF was proposed, and the optimized power-supply curve to EAF steelmaking practice was given, and electrical operation was improved, the electric energy consumption can be reduced by 25 kWh/t, and power supply time can also be reduced 3 min. |
