Abstract

1370563 Apparatus for casting MERLIN GERIN 11 April 1972 16694/72 Heading B3F Molten metal is fed to a mould 54 through a runner 46, which communicates hermetically with the top of the mould, by gas pressure acting on a molten metal bath 22. When the mould-has been filled, a valve 60 opens to connect a space 50 to the atmosphere to permit the liquid metal remaining in the runner 46 to flow back into the bath 22 on decompression of the enclosure 12. The level of molten metal in the bath 22 is sensed by a detector 44 and the amount of compressed gas supplied to the enclosure 12 in each cycle of operation adjusted so as to maintain a constant rate of flow through the runner 46. The compressed air is supplied to the enclosure via a valve 34, a preheater 36 and a controller 38, and is exhausted to the atmosphere on opening of a valve 42. The sequence of operation is controlled by a programme 62. A heating jacket 48 may be provided around the runner 46.
