<p>The method enables to carry out the degasing of a melting material, particularly non ferrous metals and aluminium, by subjecting the melting material to ultrasonic emissions. The melting material (3) flows into a transfer channel (2) from an oven (1) to a foundry (4). The ultrasound emitting device comprises a plurality of ultrasonic heads (5) mounted in the side walls and the bottom of the transfer channel. The ultrasonic heads (5) are connected to an adjustable ultrasound generator (6).</p> |
