Abstract

Methods and apparatus are provided, particularly useful in casting of aluminium, which offer pumping from a furnace to a further chamber, followed by a period of metal return back to the furnace and / or the pairing of pumps on either side of a junction conduit, with the reversal of one of the pumps causing material to flow into a spur conduit and / or a ring main situation using one or more pumps, induction heaters or casting locations and / or the pumping of molten metal from a vessel by submerging one end of an outlet conduit from the vessel below the level of the molten metal and connecting the other to the pump. Beneficial performance in casting operations is provided as a result.
