Abstract

1,239,327. Casting machines. PENNWALT CORP. 7 Aug., 1969 [17 Sept., 1968], No. 39650/69. Heading B3F. [Also in Division C7] An apparatus for vacuum processing of metals includes an evacuable chamber A containing a furnace B in which metal is melted and refined, a second chamber C adapted to contain a plurality of moulds D and connected to the chamber A by a valve E, and a tundish assembly F which receives molten metal from B and conducts it via the valve when open to said second chamber, the tundish assembly being movable so that the valve E may be closed to maintain different degrees of evacuation in the two chambers. Two tundishes may be provided to allow for failure of one, the replacement being moved through an angle by drive 86, and gears 82 and 80, the inlet end 46 of the tundishes running on rollers 53, 54, on rail 58, this same drive means being used to carry the tundish to a preheating station. In use, B is tilted so that metal pours from lip 26 into funnel 46 of the tundish and then through pipe 48 to mould D, and on completion of casting, the lefthand end of the tundish is elevated to halt the flow of metal and to lift pipe 48 so that gate valve E is no longer obstructed and may thus be closed.
