Abstract
A molten metal pumping apparatus. The apparatus has each of a circulation function and a transfer function. The apparatus includes a molten metal pump having an outlet. The pump is rotatable while submerged in molten metal to provide a first position wherein the outlet is engaged with a circulation passage in a furnace assembly and a second position wherein the outlet is engaged with a transfer passage in the furnace assembly.
Claims8
A molten metal pumping system having each of a circulation function and a transfer function, said system including a molten metal pump having an outlet, said pump being rotatable while submerged in molten metal between a first position engaged with a circulation passage in a furnace assembly and a second position engaged with a transfer passage in the furnace assembly, said circulation passage and said transfer passage being formed in a refractory wall, said wall separating a pump well housing said molten metal pump and another chamber of the furnace assembly;
- wherein an inlet to said circulation passage is parallel with an outer surface of the refractory wall and an inlet to said transfer passage is located in a notch formed in said refractory wall;
- wherein said notch extends between the circulation passage and the outer surface of the refractory wall at an angle between 30° and 80° to a longitudinal axis of the circulation passage;
- and wherein a base of the molten metal pump is received in the notch when the transfer passage is engaged.
