Abstract
Rotary device for treating molten metal has a hollow shaft with a rotor having a roof and a base spaced apart and connected by a plurality of dividers. A passage extends between each adjacent pair of dividers and the roof and the base. A flow path extends through the shaft into inlets of the passages and out of outlets. A chamber in which mixing of the molten metal and gas can take place is located radially inwardly of the inlets, has an opening in the base of the rotor and is in the flowpath between the shaft and the inlets. Upon rotation of the device, molten metal is drawn into the chamber through the rotor base where it is mixed with gas passing into the chamber from the shaft. The metal/gas dispersion is pumped into the passages through the inlets before discharge from the rotor through the outlets.
