    摘要: An arc furnace, a control and/or regulating device for an arc furnace, and a method for operating an arc furnace are provided, wherein an arc for melting metal is generated by at least one electrode, wherein an arc associated with the electrode(s) has a first radiation power based on preselected operating parameters, wherein the arc furnace is operated according to a predefined operating program based on an expected process sequence, wherein monitoring is performed to detect whether an undesirable deviation exists between the actual process sequence and the expected process sequence. Because a modified second radiation power is specified if a deviation is present, and a modified second set of operating parameters, e.g., impedance value(s), is determined based on the modified second radiation power, a method is provided that permits a minimal melting time while minimizing consumption of operating resources, e.g., with respect to arc furnace cooling.

    摘要: A method for controlling a melt process in an arc furnace and signal processing component, program code, and data medium for performing said method are provided. According to the method, sound signals or vibrations from the interior of the furnace container are captured by solid-borne sound sensors, from which characteristic values can be derived for the distribution of melting material, melt, and slag in the furnace fill. A characteristic value SM for thermal radiation impinging on the furnace wall of the container, a characteristic value M for the lumpiness of the melting material in the volume of furnace fill, and a characteristic value MM for the change to the portion of solid melting material contacting the furnace wall are generated in priority sequence. The energy distribution at the electrodes is changed by a control system analyzing the characteristic values in priority sequence, such that thermal load peaks are dampened or even completely prevented. To this end, the strand impedances stored as target values are modified. If the control is not sufficient, the thermal power of the arc is reduced as a subordinate means. A rapidly and reliably effective operating regime for the processes in the arc furnace can thereby be implemented.

    摘要: An electric arc furnace, signal processing device, storage medium, machine-readable program code, and method for determining a time for charging (e.g., recharging) an electric arc furnace with material to be melted (e.g., scrap) are provided. The electric arc furnace may include electrode(s) for heating material inside the electric arc furnace by an electric arc.
