The research presents the comparative analysis of the most common electrical mode control systems for electric arc furnaces (EAF) and ladle furnaces (LF) produced by the leading foreign companies, i.e. Siemens VAI (Primetals Technologies), Danieli, Amec Spie , AMI, Ferrotron. The comparative analysis criteria are
the functionality requirements for the electric mode control systems, which ensure optimal operation of the furnace units at minimum production costs. Such analysis allows solving various tasks related to the electric steel-making production planning, as well as to basic technological equipment supplier selection. The results of the comparative analysis are of significant practical importance, since in a number of cases, the studies into the furnace units’ operation optimization show no technical possibility to achieve the required energy and time levels due to the limitations posed by the architecture of the electrical mode and the electrode motion control system.
