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.

Plant for casting metal with particles suspended therein

When pouring casting cavities in casting moulds having after-feeding reservoirs, tubular lances are introduced, firstly with their point at a short distance from the after-feeding reservoir, after which the lances are pressurized from a pressure chamber and by means of a member with an inclined surface pressed downwardly through the last short distance to the after-feeding reservoir so as to pressurize the latter. With this arrangement it is possible to pressurize the after-feeding reservoirs without the need of equipping the casting moulds with complicated extra equipment and without risk of the molten metal being pressurized unnecessarily.
