Abstract
The invention relates to a device for supplying casting installations with molten metal. Said device comprises a crucible into the melt of which a dosing pump dips and supplies a discharge tube (12) communicating therewith with melt. The discharge tube (12) and the pump tube (11) are interlinked via a U-shaped connecting tube (15) to give a one-piece crucible insert. The discharge neck (13) of the discharge tube (12) is mounted so as to be swivelable about the axis (30) of the discharge tube. The inventive design allows for a simple maintenance and production of the dosing device. Moreover, the crucible position no longer has to be adapted to the position of the casting installation.
Claims15
A device for charging casting devices with molten metal, comprising:
- a crucible;
- a metering unit having a metering pump with a pump part projecting into the crucible and a discharge pipe;
- wherein the metering unit is designed as a crucible insert having a lid cover flange removably attachable to a cover of the crucible, and wherein the lid cover flange can be placed upon the crucible cover and lifts off the crucible cover while the crucible cover remains in place on the crucible;
- and
- wherein the pump part projecting into the crucible contains a pump pipe that extends through an associated passage opening of the lid cover flange and is connected to the discharge pipe, and the discharge pipe is held swivellably in an associated passage opening of the lid cover flange.
