Abstract (en)

[origin: WO2021198334A1] The present invention relates to a method (100) and a system (1) for compensating for electrode (2) burn-off in an arc furnace (3). At least a part of the electrode (2) held in a first retaining position (H1) by a retaining device (4) is detected (S1) with the aid of a sensor device (5) and a second retaining position (H2) is determined (S2) on the basis of data generated during the detection. The retaining device (4) can then be repositioned (S4) relative to the electrode (2) from the first retaining position (H1) to the determined second retaining position (H2).
