| 20100332160 | METHOD FOR DETERMINING A RADIATION MEASUREMENT FOR THERMAL RADIATION, ARC FURNACE, A SIGNAL PROCESSING DEVICE PROGRAMME CODE AND STORAGE MEDIUM FOR CARRYING OUT SAID METHOD - 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. | 12-30-2010 |
