A system for generating mechanical waves for use in smelting and conversion processes that occur in furnaces and converters for a higher production of refined metals, consisting in an electrical signal generator, transducers that convert said electrical signals in mechanical waves placed on the outer end of air blowing tuyeres and a coupling means between said system and the shell of the converter. The air blowing tuyeres are placed forming an angle less than or equal to 90° with the transducer and the airflow entrance to the interior of the converter, forming a figure with an alpha angle shape; and the transducer is placed in the direction of the cross axis of the converter pointing towards the alpha angle of the air blowing tuyere, for applying mechanical waves that travel in a longitudinal direction with the airflow into the converter. The field of mechanical waves allows a higher efficiency in the oxygen reactions within the metal bath and slag, increasing the kinetics of chemical reactions, allowing a quicker homogenisation of the metal bath and reducing notoriously the copper trapped mechanically by the slag, all this leading to a higher production of metal.
