Electrical optimization of superpowerful arc furnaces

Abstract: Requirements on the systems controlling the electrical conditions of superpowerful arc furnaces in steel smelting are outlined. The basic principles for electrical optimization at different phases of smelting are considered. An improved mathematical model is proposed for analysis of the arc furnace's electrical char acteristics and the dynamics of the automatic control system governing electrode motion. A diagnostic system capable of identifying the phase of smelting on the basis of the harmonics of the arc cu… Show more

“…Early works focus on building mathematical models for the dynamics inside EAF considering domain knowledge while recently more interests have been attracted to data driven based dynamics analysis and EAF modeling for optimizations. Nikolaev, Kornilov, Anufriev, Pekhterev & Povelitsa (2014) presents a detailed control mechanism used to optimize EAF. In the work, the authors develop a mathematical model to analyze electrical characteristics of EAF and the dynamic behavior of the automatic control system.…”

“…In MacRosty & Swartz (2005), melting processes and chemical reactions are analyzed. As in Nikolaev et al (2014), the authors explore mathematical modelling techniques to analyze steel-making processes of EAF and develop a dynamic model for the processes. Data driven analysis has been conducted for parameter estimation with real site data such as off-gas composition, but it seems like the volume of collected data is rather limited.…”

“…This trend introduces the main task of further improving the automatic control systems of electric arc furnaces to reduce energy consumption, increasing energy efficiency, electromagnetic compatibility and sustainability [1]. The most important way to achieve 2 of 19 this is to improve the automatic control system (ACS) of electric mode (EM), arc length control systems, as well as melting technologies and arc furnace design [2].…”
