Definitions

  • the present invention regards an melting furnace for metal leagues of second melting with a special type of connection between the primary parts of the furnace system, the cupola and the basin of wait especially conformed and able to rotate, so that to realize a combined system of making without giving place interruptions of the cycle of work.
  • the first phase is constituted by the loading, in the melting furnace or cupola, of the league scrap and its melting. During this phase it is necessary to furnish remarkable quantity of caloric energy fit to produce the necessary specific heat to the melting of the material and a further quantity of energy, latent heat, necessary to the maintenance of the liquid phase of the metal in the time that is completed the melting of the whole scrap charge present in the cupola.
  • the second phase consists in the blowing out of the furnace and consequent partial cooling to allow the poured of the melted material, to means of special pouring channels, toward the basin of wait.
  • the pouring channels are realized generally with runs to open sky that behave a further cooling of the melted metal.
  • the third and last phase is constituted by the transformation of the material in league in the basin of wait with corrections and additions of metal as well as reinstatement of the caloric energy, constituent the specific and latent heat, necessary to make up for dissipated energy during the inevitable cooling that is had among the before and the second phase.
  • the long times of melting and poured of this technique they favor the absorption of remarkable quantity of gas of the melted material, much is that in the basin it is often had to also apply to a type of correction that foreseed the addition in the bath, through injection of liquid nitrogen, to degasify the league so that to get ingots and pigs exempted by defects.
  • Purpose of the present invention is that to eliminate the inconveniences in the preceding technique realizing an melting furnace that with a special connection allows the poured direct and continuous way of the melted metal from the cupola to the basin of wait able to rotate, and from this last to the ingot mould, decreasing the energetic costs and times of management and employment of hand of work and, at the same time, also realizing good conditions in safety terms of the job because the employees are not to contact with the melted material since the making cycle happens, in practice, completely to the closed one.
  • the continuous making cycle avoids, therefore, the interruptions, for the blowing out and the cooling of the first part of the furnace with least supply, in the second part, of further caloric energy assuring, therefore, the saving of fuel, time and hand of work.
  • the fig. 1 shows in schematic way a lateral view in section of the furnace; the fig. 2 shows in schematic way a view from the top and in section of the furnace; the fig. 3 shows in schematic way the rotating channel of connection.
  • the cupola essentially of cubic form with walls in material refractory (2) surrounded by a metal shirt (3), in which is present on a side the burner (4), on another side the door of load (5) and on the opposite side, centrally in low, an opening (6) from which the melted metal escapes for reaching, through the channel of poured (7) the basin of wait of spherical form (8) that is placed on a lower plan, in a pit (9), sustained by elements of support (10).
  • the channel of poured (7) realizes a special rotating joint, between the cupola (1) and the basin of wait (8), constituted by two hollow cylindrical bodies to circular section, adequately heat insulated (11) and (12), fixed each for an extremity (13) and (14) respectively to the cupola (1) and to the basin of wait (8) and the other free extremity of each (15) and (16), coaxially inserted one in the other.
  • the basin of wait of spherical form (8) is constituted by two semispheres set one on the other, with walls in refractory (17) and heat insulated (18) surrounded by a metallic shirt (19) and positioned in a pit (9) sustained by supports (10) in such way that his meridian circumference is practically to the same height of the channel of poured (7).
  • a burner (20) is placed and the orifice of exit (21) of the liquid metal. The metal scrap a melted time in the cupola, it comes out from the opening
  • the invention fulfils its objectives completely .
  • the particular adopted geometric form (spherical body) of the basin of wait it exalts and improves the whole procedure of the technological cycle of production.
  • the said constituent parts can work in contemporary realizing, so, a continuous melting system with notable saving of fuel, of time and hand of work; they are gotten, therefore, economies with percentages also of the fifty percent in comparison to the standards of the systems of the preceding technique.
