APPARATUS AND METHOD FOR THE SUPPLY OF MOLTEN METAL

摘要

A holding furnace (1) for supplying molten metal to a casting launder (11) i s disclosed including a metal chamber (9), an outlet (7a) from said metal chamber and an inlet well (5) positioned on the holding furnace (1) on or adjacent to the pivot axis (4) of the holding furnace. The inlet well is axially displaced along the pivot axis from the outlet (7a) of the holding furnace so that the motion of molten metal entering through the inlet well does not disturb the level of molten metal i n the launder (7). The holding furnace (1) may be incorporated into an apparatus for supplying molten metal to a casting launder preferably including a transfer conduit (2) having one end submerged below the level of metal in the inlet well and the other end submerged below the level of metal in a molten metal source (3). The flow of metal into the inlet well is controlled to minimize turbulence and allow the holding furnace to supply a steady, continuous flow of metal to a launder (7) while being intermittently charged with molten metal from the molten metal source (3).
