  • Multifunction injector and relative combustion process for metallurgical treatment in an electric arc furnace
    Patent number: 7611563
    Abstract: A multifunction injector (10, 11, 12) comprising a De Laval nozzle (20) adapted to act as a burner at subsonic or supersonic speed, combined with a plurality of nozzles (31, 32) for fuel and comburant respectively, arranged in two rings, concentric and co-axial to said De Laval nozzle (20) and externally protected by a specifically shaped protection cavity (40).
    Type: Grant
    Filed: February 13, 2006
    Date of Patent: November 3, 2009
    Assignee: Techint Compagnia Tenica Internazionale S.p.A.
    Inventors: Francesco Memoli, Mauro Bianchi Ferri, Marcello Pozzi, Enrico Malfa
  • Pyrometallurgic process for the treatment of steelwork residues
    Patent number: 7435281
    Abstract: A pyrometallurgic process for the treatment of post-steelwork residues, comprises the following phases: preparing a furnace (1) of the electric type, suitable for the introduction of the residues; preparing the residues, for example in a hopper with the possibility of mixing with additives and reaction elements; introducing the residues, together with suitable additives and chemical reagents, into the furnace (1); introducing directly into the slag, by means of lances (4), additives, flushing and reaction elements to correct the composition of the slag (7); reacting the residues with the slag (7) to obtain: a) separation of the liquid metallic phases which are added to the metal bath (6) to form a sellable liquid metal; b) separation of the metallic volatile elements in vapour phase which, when transferred to the free zone of the furnace (1) recombine with the oxygen for the formation of oxides and consequently of powder.
