METHOD FOR OPERATING AN ARC OVEN AND MELTING ASSEMBLY WITH AN ARC OVEN OPERATED ACCORDING TO THIS METHOD
The method involves detecting an impact sound signal (S) entering to a wall of an electric arc furnace (2), and calculating a parameter i.e. measured value, characterizing flicker properties of the furnace from the sound signal, where the furnace comprises electrodes (4a-4c). A process variable of t...

| description | The method involves detecting an impact sound signal (S) entering to a wall of an electric arc furnace (2), and calculating a parameter i.e. measured value, characterizing flicker properties of the furnace from the sound signal, where the furnace comprises electrodes (4a-4c). A process variable of the furnace is controlled based on the calculated parameter. The sound signal is subjected to Fourier transformation, and a measure for low-frequency scrap movement is detected from amplitudes of the transformation when frequency lies below a fundamental frequency. An independent claim is also included for a melting assembly. |
