ABSTRACT:
A low pressure casting process using a furnace of the channel-type induction for heating, the furnace power being automatically controlled by direct temperature measuring of the molten metal bath according to the desired casting temperature. The feeding chamber of the furnace is of pressure-type and has a protective gas with a slight over-pressure. The furnace is filled via a syphon-shaped feeding chamber whereby metal is inserted below the level of molten metal in the feeding chamber and the protective gas therein is not affected. An operator starts the casting process whereby a casting mold is closed and assumes a casting position over the casting nozzle from the furnace and metal is forced into the mold. The mold, one of several on a carousel is moved to a station wherein the casting is automatically discharged to a conveyor belt. The mold next moves to an immersion bath where it is treated, and then to a preparation station wherein it may be cleaned and cores inserted. Finally, the mold returns to the casting station. Three such molds are shown which rotate simultaneously about a common axis of the carousel. The support for each mold permits the opening of the mold into mold halves for the immersion station and the tilting of the mold for the preparation station.
