Abstract
One of the most important factors in successful electric steelmaking is the continuous observation of the process and the reaction to it. Traditional electric arc furnace control uses mainly direct controls which are based on the electric power input. Not considering the furnace conditions will necessarily lead to suboptimal operation in terms of energy consumption and productivity not fully utilized.The ARCCESS FEOS (Furnace Energy Optimization System) includes the simultaneous control of the transformer tap, impedance operating point, reactor tap, burner and carbon injection, and DRI charging control. FEOS has proven in practical operation benefits of high melting yields, no interruptions through switch offs in borderline temperature area, rapid reaction, reproducible and efficient electrical energy input and short power-on times.
