Definitions

  • the invention relates to a casting method for aluminum or aluminum alloys according to the preamble of claim 1 and a casting installation for carrying out the method.
  • At least two filled pans can be provided at the casting station, one of which is emptied into a common inlet channel, so that a continuous casting process can be ensured.
  • the successive emptying of the provided pans can be done by preferably controllable opening of their sliding closures.
  • the pans need not be transported to another treatment station and from there to the casting station, but the treatment of aluminum melt can be done with advantage in the provided at the pouring station, the emptying not yet suspended pan or pans.
  • Fig. 1 shows an embodiment of an inventive casting plant for
  • FIG. 2 shows the casting plant according to FIG. 1 in plan view.
  • a casting plant for aluminum or aluminum alloys is shown schematically, in which aluminum scrap is introduced into a melting furnace 10 as a starting material.
  • blocks intended for remelting could serve as starting material.
  • the melt produced in the melting furnace 10 is introduced into a heat-holding chamber 12 of a filling station 11, from where it is filled at regular intervals by means of a dip tube 13 each in a pan 15.
  • the smelting furnace 10 may preferably be an induction furnace having, for example, a capacity of 1.75 tons and in which 2 tons of material per hour may be melted. From the heat holding chamber 12 with a capacity of 3.5 t pans can then be filled with a capacity of 2 t, each remaining the remaining 1.5 t for further charge in the heat holding chamber 12 remain.
  • pans 15 are preferably transported directly to a casting station 20, which is, for example, a per se known continuous casting with a number of molds 21st and in which the actual casting process takes place.
  • a casting station 20 which is, for example, a per se known continuous casting with a number of molds 21st and in which the actual casting process takes place.
  • a possible treatment of the molten aluminum is preferably carried out in the ladle or pans 15, 15 'provided at the pouring station 20 and not yet emptied.

Abstract

La présente invention concerne un procédé de coulée et/ou un appareil de coulée pour l'aluminium et/ou les alliages d'aluminium, permettant de verser la masse fondue d'aluminium est versée dans un certain nombre de poches de coulée (15, 15'). Un traitement est effectué dans tous les cas dans ces poches de coulée (15, 15') et ladite masse fondue est amenée à un poste de coulée (20), dans lequel elle est alors vidée et ainsi coulée pour former des produits semi-finis. Afin de garantir un processus de coulée continu, au moins deux poches de coulée remplies (15, 15') sont mises à disposition au poste de coulée (20), la masse fondue étant vidée respectivement de l'une d'entre elles dans un canal d'amenée (27) commun.
