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. |
