Optimal Modeling in SR-EAF Power Supply Curves

Analyzing the electric characteristics of a supplemental reactor electric arc furnace(SR-EAF) and comprehensively considering the influencing factors on production cost,we developed an optimized power supply model,where the multiple objects aiming at shortening smelting time,reducing electric power consumption per ton of steel,decreasing electrode consumption and prolonging lining life were employed in optimization.The effects of current on electrodes and linings and effects of a supplemental reactor and the output voltage of a transformer on power supply strategy were taken into account in this model,with such parameters optimized as the current of electric arc,the values of a supplemental reactor and service voltage.A new power supply strategy based on the optimized parameters was proposed and applied in actual production,which increased power supply efficiencies and economic benefits.
