摘要

Method for determining a charge time for charging an electric arc furnace with material to be melted, signal processing device, machine readable program code, storage medium and electric arc furnace. The invention relates to an electric arc furnace, a signal processing device, a storage medium, a machine readable program code and a method for determining a time to charge, in particular recharging, a furnace. electric arc (1) with material to be melted (g), in particular scrap, wherein the electric arc furnace (1) comprises at least one electrode (3a, 3b, 3c) for heating molten material (g) which is disposed within the electric arc furnace (1) by means of an electric arc. detecting a first signal (s) to determine a phase state of an electric arc base on the side of the material to be fused at the base of a detected electrode current (i ~ k ~) by checking whether the first signal (s) exceeds a predetermined limit value for a predetermined minimum duration and ensuring that the charging time is reached at the earliest when the first signal exceeds the predetermined minimum duration limit, a charge-oriented charging time for electric arc furnace operation. It can be determined to reduce energy use, resource use and production time for a production cycle to achieve a tap weight.
