Definitions

  • the invention relates to a casting device comprising a melt transport device and a preheating station for preheating a melt transport device, as well as a method for preheating the melt transport device by means of the preheating station.
  • AT 523 252 A1 is a melt transport device with at least one melt container in which a melt receiving chamber and a spout in the form of a lance located at the bottom of the melt container are formed, wherein the spout has a spout opening which is flow-connected to the melt receiving chamber.
  • melt transport devices are from the US 2012/146267 A1 , the CA 1 137 302 A , the CN 113 547 110 A , the US 4 359 209 A and the CN 108 655 384 A known.
  • the object of the present invention was to provide an auxiliary device for the casting device and a casting process by means of which an improved casting result can be achieved.
  • the casting device offers the advantage that, by means of the preheating station, the melt receiving chamber of the melt transport device can be brought to a sufficiently high temperature so that, upon commissioning or initial filling of the melt transport device, the melt encounters already pre-tempered surfaces. This largely prevents oxide formation during the melt intake. Oxide formation can be prevented by reducing the local cooling of the melt. Particularly with aluminum melts, this can improve the melt quality, as aluminum melts are especially prone to forming an oxide layer upon local cooling.
  • the preheating station offers the advantage that, with it, the melt receiving chamber of the melt transport device can be brought to a sufficiently high temperature so that, upon commissioning or initial filling of the melt transport device, the melt encounters already pre-tempered surfaces.
  • Oxide formation can be prevented by reducing the local cooling of the melt. This can improve melt quality, especially with aluminum melts, as aluminum melts are particularly prone to forming an oxide layer upon local cooling. Furthermore, this measure can prevent local solidification of the melt on a cold surface.

  • the second temperature sensor can be connected to the computing unit via a data line.
  • the second temperature sensor can be connected to the computing unit wirelessly.
  • the blower can be positioned upstream of the air heater when viewed in the direction of airflow. This has the advantage that the air flowing through the blower is not yet heated, which can increase the blower's service life.
  • the air heater can be positioned as close as possible to the transition to the melt transport device. This measure minimizes heat losses and thus maximizes energy efficiency.
  • Another advantageous design is one that incorporates a return channel, allowing at least portions of the exhaust air stream from the melt transport device to be returned to the flow channel. This offers the benefit of improved energy efficiency.

  • a free outlet duct for the heated air can be provided in the form of a chimney.
  • a shut-off device can be installed in the chimney.
  • the second temperature sensor can be located in the melt receiving chamber of the melt transport device. This offers the advantage that not only the output temperature of the preheating station but also the actual temperature within the melt transport device can be measured. This allows for more precise setting of the desired temperature within the melt transport device.
  • the second temperature sensor can be positioned above a maximum fill level within the melt receiving chamber. This largely prevents contamination of the second temperature sensor by melt, thereby extending its service life.
  • the second temperature sensor can be protected from below by a splash guard.
  • the method according to the invention offers the advantage that the melt receiving chamber of the melt transport device can be heated to a sufficiently high temperature so that, upon commissioning or initial filling of the melt transport device, the melt encounters already pre-tempered surfaces.

  • the air volume is conveyed into the melt transport device until a temperature between 200°C and 450°C, in particular between 250°C and 420°C, preferably between 300°C and 390°C, is reached in a melt receiving chamber of the melt transport device, and that in a subsequent process step the melt transport device is used for casting a workpiece.
  • a temperature between 340°C and 360°C in the melt receiving chamber can be targeted.
  • a melt transport device pre-tempered to this temperature offers the advantage that Oxide formation during the intake of melt into the melt intake chamber can be largely prevented.
