METHOD OF TRANSFERRING MOLTEN METAL

摘要

A method of transferring molten metal from an upper source reservoir to a lower reservoir using an inverted substantially U-shaped conduit (3) having a curved section (4) and two leg sections (7, 8). Molten metal is drawn up into the upper, generally shorter leg (7) of the conduit to partially fill the conduit. The level of vacuum in the conduit is then controlled to prevent the curved section of conduit completely filling with molten metal and provide a controlled and/or constant flow of molten metal to the lower reservoir (2).
