Abstract:

An air cooled molten metal pump frame includes a base structure and molten metal pump supporting structure comprising tubular members to facilitate flow of cooling air therethrough. The cooling air flowing through the molten metal pump frame provides cooling to the pump frame to minimize distortion and deformation due to the high temperatures caused by an adjacent molten metal bath. The cooling air flowing through the pump frame can also be directed to the molten metal pump to cool pump components. The tubular frame also facilitates simple and effective connection between a source of electrical power and the molten metal pump while shielding the electrical wiring from heat damage due to the proximity of the molten metal bath. The molten metal pump frame is particularly adapted for supporting molten metal pumps used in aluminum reclamation furnaces.
