MELTING FURNACE

摘要

The invention relates, inter alia, to a melting furnace (10). According to the invention, at least one vibration inducer (40, 41, 42) is installed on a furnace vessel (20), at least one sensor (50, 51, 52) is arranged opposite or at another place on the furnace vessel and a signal recording and calculation unit (90) is connected to the at least one vibration inducer and the at least one sensor. In this way, for example, 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 means of this sensor and evaluating the signals by means of the signal recording and calculation unit. This makes it possible, for example, to carry out process-controlled, state-oriented regulation of the melting process and match the electric arc power optimally 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.
