Abstract
Molten metal (,) in a furnace (,) and containing particles of solid material (not shown) in suspension is cast in moulds (,) conveyed continuously past the mould-filling station shown by a conveyor (,). To maintain the particles in suspension and keep the metal (,) homogeneous throughout the furnace (,), a paddle-wheel rotor (,) driven by a motor (,) keeps the molten metal in constant movement. A curved guide vane (,) is shaped, placed and oriented so as to divert some of the centrifugal flow from the rotor (,) towards the delivery tube (,) for the moulds (,), thus ensuring that the tube (,) is supplied with freshly-agitated metal.
