On the Problem of Symmetring the Electric Modes of Alternating-Current EAF
The paper presents the description of features of arc furnaces asymmetric electric modes with «asymmetric triangle on electrodes» short network connection. Based on experimental data from DSP-100 arc furnace the influence of electric modes parameters on electric arcs characteristics was analyzed. It was found out, that a non-uniform power distribution within electrothermal unit phases contributes to the reduction of the useful power which is spent on metal and slag heating. For the electric arc furnace which is under consideration an unrealized potential of the reduction specific electric power consumption is 7.4%, electrodes specific consumption is 9%. Obtained results confirm the research relevance in the field of design and implementation of methods and means of the phase power control in AC electric arc furnaces.
