Abstract (en)
[origin: EP1512764A1] A metal-melting furnace comprises a main chamber (26), a circulation chamber (28) in operative communication with the main chamber and a well block (38) disposed within the circulation chamber (28). A vortex well (84) is formed within the well block and is adapted to hold a maximum quantity of molten metal therein. The vortex well has an exit outlet (96) for recovering molten metal therefrom. A containment means (108) is emplaced over the vortex well (84). A gas bubble actuated molten metal pump (48) is contained within an end block (36) which engages the well block (38) and has an entry port in operative communication with the circulation chamber (28) and an exit port (64) in operative communication with the vortex well (84). The exit port is tangentially arranged with respect to the periphery of the vortex well. <IMAGE>
