Abstract (en)
[origin: CZ304029B6] The rotary device for refining molten metal according to the present invention consists of a cylindrical rotor being fastened on a hollow shaft and having a cavity that is open at the bottom and interconnected at the top with a supply channel in the shaft, whereby radial outward enlarging passages separated by partitions extend from the cavity. The partitions (5) pass on the rotor (1) outer jacket over into ribs (6) extending along the rotor (1), wherein the ribs (6) pass at their lower end over into radial projections (7) performed on the rotor (1) bottom side (1).
