Abstract This article deals with possibilities of using a hydraulic press in production of large forged rings. These rings are used in nuclear or petrochemical industry. Three methods for their production are supposed and evaluated in terms of energy. Because production of large rings causes specific loading of hydraulic press, FEM simulation is performed. The result is complex design for large rings production machine. © 2014 The Authors. Published by Elsevier Ltd. Selection and peer-review under responsibility of DAAAM International Vienna.
