1. A process for introducing gas into a metal melt present in a metallurgical vessel via ducts arranged in a refractory lining of the vessel, the process comprising the steps of:

  • introducing gas into a gas distribution antechamber;

    subsequently passing the gas around a first acoustic generator to create an oscillating jet of gas;

    feeding the oscillating jet of gas to at least one second acoustic generator and exciting the jet of gas to periodic oscillations;

    conducting the oscillating, excited gas jet into a gas-distribution main chamber; and

    feeding the gas jet from the main chamber via the ducts to the melt contained in the vessel.
