ABSTRACT:
A fan wheel for high-temperature operation, especially in ovens, includes a star-like or ray-like base plate having a central middle region, protrusions protruding substantially radially beyond the central middle region and having an outer contour, axially drawn up blades disposed on the protrusions and a base plate surface with axially drawn up segments extending from the middle region into the vicinity of the protrusions. According to one embodiment, the segments include a central, annular segment and star-like or ray-like segments adjoining the central, annular segment and extending through the protrusions of the base plate substantially symmetrically with the outer contour. According to another embodiment, the segments include a central, annular segment and star-like or ray-like segments adjoining the central, annular segment, originating from the central, annular segment and following the outer contour of the base plate. A method for manufacturing a high-temperature fan wheel includes initially axially drawing shapings and optionally bulges from a flat, preferably metal blank and subsequently cutting away the contour of the base plate and bending the blades relative to the base plate.
