Voltage-current characteristic mathematical modeling of a direct current arc of a power steel furnace and its introduction into the program complex SALOMON

The electrical arc furnaces of a direct current (EAFDC) have a lot of relevant advantages in comparison with furnaces of alternating-current. Low level of usage of electrodes and energy, a flame resistance, stable combustion of an arc, minor deterioration of quality parameters of the electric power concern to such advantages. But the most important advantage of EAFDC as contrasted to furnaces of alternating current is lower flicker effect. Desirable value of voltage of direct current furnaces is supported irrespective of current intensity, which one is controlled by separate thyristors. The aim of the research is the mathematical modeling a voltage-current characteristic (VCC) of an arc of a power steel furnace of a direct current and introducing it into the SALOMON program complex.
