The comparative analysis of electrode control systems of electric arc furnaces and ladle furnaces

The article presents the comparative analysis of electrode control systems of electric arc furnaces and ladle furnaces illustrated by example of ARCOS (Siemens VAI, Primetals Technologies), HIREG (Danieli), EMPERE (Amec Spie) and DECTEQ (Ferrotron). The functional scheme for the following systems presented offers the main algorithms of electrode regulating. Main advantages and disadvantages are mentioned below. Besides, in the frames of our study, the authors present description of the Russian system of electric mode control ASEMC RADUGA NPA LF having a number of advantages in comparison to foreign models.
