Abstract
Aspects of the invention relate to a rotor for transferring molten metal. A powered device, such as a molten metal pump, which may be inside of a transfer chamber, includes a multi-stage rotor to move molten metal within a vessel. The molten metal may be moved out of the vessel and into another structure, which could be another vessel or a launder. The multi-stage rotor may have multiple blades with each blade having multiple surfaces.
Claims15
A rotor with blades for directing molten metal towards a rotor interior and away from the rotor interior, the rotor comprising one or more rotor blades, wherein each rotor blade comprises:
- (a) a first portion having a first surface angled to direct molten metal towards the rotor interior;
- (b) a second portion separate from, juxtaposed to, and at least partially closer to the rotor interior than the first portion, and having a second surface angled to direct molten metal towards the rotor interior;
- and
- (c) a third portion separate from, and juxtaposed to the second portion, and having a third surface for directing molten metal outward from the rotor interior.
