摘要： In a method, a variable characterising an operational state of an electrode of an arc furnace can be determined. An electrode flow guided to the electrode is detected in the method and the structure-borne noise oscillations are detected. From the detected electrode flow, a flow evaluation signal associated with the frequency range of the detected electrode flow is determined. From the detected structure-borne noise oscillations, an oscillation evaluation signal that is associated with a frequency range of the detected structure-borne noise oscillations is detected and a quotient from the oscillation evaluation signal and the flow evaluation signal is formed as a radiation measurement for at least one frequency common to the detected electrode flow and the detected structure-borne noise oscillation.

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： In a melting furnace, a vibration inducer is installed on a furnace vessel, a sensor is arranged opposite or at another place on the furnace vessel and a signal recording and calculation unit is connected to the vibration inducer and the sensor. The melting process can be monitored and the progress of melting can be measured by measuring the signals of the vibration inducement after having passed through the interior of the furnace by this sensor and evaluating the signals of the signal recording and calculation unit. Thus, process-controlled, state-oriented regulation of the melting process can be carried out and the electric arc power is optimally matched to the respective state of the melting process. The signal of the sensor is preferably correlated with the excitation signal of the vibration inducer and/or conclusions are drawn about the melting process by combined evaluation of the vibration inducement and the measured vibration.

摘要： In a method for determining a state variable of an electric arc furnace, especially for determining the level of the foamed slag (15) in a furnace, the energy supplied to the furnace is determined with the aid of at least one electric sensor while solid-borne noise is measured in the form of oscillations on the furnace. The state variable is determined by a transfer function which is determined by evaluating the measured oscillations and evaluating measured data of the electric sensor. The state of the foamed slag level can thus be reliably recognized and be monitored over time. The foamed slag level is decisive for the effectiveness with which energy is fed into the furnace. Furthermore, losses caused by radiation are reduced by covering the arc with the foamed slag. The improved measuring method allows the foamed slag level to be automatically controlled or regulated in a reliable manner.
摘要翻译：在用于确定电弧炉的状态变量的方法中，特别是用于确定炉中发泡炉渣（15）的水平时，借助于至少一个电传感器确定供应给炉的能量，在炉子上以振荡的形式测量负载噪声。状态变量由传递函数确定，传递函数通过评估测量的振荡和评估电传感器的测量数据来确定。因此，可以可靠地识别发泡渣水平的状态并随时间进行监测。泡沫炉渣水平对于将能量送入炉子的有效性是决定性的。此外，通过用发泡炉渣覆盖电弧来减少由辐射造成的损失。改进的测量方法允许以可靠的方式自动控制或调节泡沫炉渣水平。

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.
