Low pressure molten metal casting device |
摘要 |
A low-pressure molten metal casting device comprising a level detector or sensor disposed in a column disposed downstream of the smelting furnace and upstream of the casting leading inlet feed openings of a distribution chamber connected to the moulds. This sensor co-acts with a mechanism controlling the pressure of an inert gas in the furnace for regulating the metallostatic casting overpressure as a function of the selected casting level in order to monitor the furnace pressure and consequently the casting by moving the sensor according to a predetermined law or with the assistance of the gas pressure in the column, so as to reduce any idle periods between successive castings cycles by pre-rising the molten metal by using the level sensor, the latter comprising preferably a pair of staggered electrodes.
