ABSTRACT:
A method of melting and casting metal comprising the steps of melting metal in a melting vessel, transferring metal from the melting vessel into a casting vessel by flow of metal under gravity and pumping metal against gravity from the casting vessel into a mold. The level of the top surface of the metal as the metal leaves the melting vessel is above the top surface of the metal in the casting vessel by not more than a maximum distance above which excessive turbulence occurs. The maximum distance lies in the range 50-200 mm.
