Sažetak

This paper presents the analysis of the adverse impact of the current oscillations on electric power losses in the manufacture of flat rolled products. The results of mathematical processing of experimental data for the study of the influence of transient processes in the cold rolling mill electromechanical systems on the rate of power losses during rolling are discussed. The negative effect caused by power losses has been evaluated and focus areas to reduce the operational costs have been identified. In addition, technical measures aimed at minimizing oscillation processes during rolling have been proposed.
