Abstract

See full text

The invention relates to a stirrer organ in composite construction comprised of a metallic part and a hybrid casting, with the hybrid casting being fixed to the metallic part by means of at least one anchoring element which forms at least one back-cutting in the hybrid casting. Furthermore, the present invention relates to a method for rehabilitating a damaged metallic stirrer organ which when applied provides a rehabilitated stirrer organ in composite construction. The invention tackles the task of creating a stirrer organ in hybrid construction which features a largest possible metallic part because higher strength can hereby be achieved. This task is inventively solved in that the anchoring element is provided with a perforated plate which is spot-wise fastened to the metallic part and which is arranged at least partly at a small distance to the surface of the metallic part so as to configure the at least one back-cutting.
