摘要
Disclosed are an apparatus and method for process-based power regulation of an electric arc furnace (10). A plurality of sensor types (15, 16, 17) detect presently active operating parameters of the electric arc furnace (10) in dependence on time. From the measured values, a control and regulating unit (30) determines the necessity of whether to switch other winding taps (TS1 . . . TSN) of the primary side (6P) of the furnace transformer (6) by a semiconductor tap changer (20) in order to effect a modified electrical power to prevent thermal and/or mechanical damages to the electric arc furnace (10).
