Abstract
Results of a study of the properties of the metal of three model rotors man ufactured from vacuum-degassed open-hearth steel 36KhN3MFA melted by differ ent methods are presented It is recommended that standard generator rotors be manufactured from a mixture of acid and basic melted steel. Two rotor pr eforms for a 1200-MW generator were manufactured and studied. The forging a nd heat-treatment techniques for the rotor preforms are described. The prop erties of the metal of these preforms are shown to correspond to the requir ements of the specifications.
