Definitions

  • the present invention relates to a two-stage control of a casting process with two mutually independent casting speeds, the melt being driven by means of a pressure which can be changed twice, from an oven containing the melt, through a casting tube into the casting cavity of a mold.
  • the casting furnace (15) automatically compensates for the discharge of the melt with pressure by means of the level display (23) each time the casting is carried out. That the melt reaches the level edge (18) at the pouring tube (19). And remains until the casting model (14) is pressed onto the casting tube (19). And at the moment the second stage (Flg. 2.) sets in motion.
  • Their invention consists in that the casting model (14), once set, is always filled with exactly the same time.
  • the purpose of the present invention is to provide a method without the disadvantages mentioned, in which a sensitive and precise control of the filling speed can be achieved in a relatively simple manner, so that a high, consistent casting quality is ensured. According to the invention, this is precisely described in the claims 1, 2 and 3 and with the plan.
