Research on Key Processing Technology of Nuclear Power Tapered Cylinder Forging

Abstract:

AP1000 steam generator of nuclear power is an important equipment in the PWR nuclear power plant and the structure of its bi-straight tapered cylinder forging is complex, which increases forming difficultly. In this paper, forming process of bi-straight tapered cylinder forging is determinated by numerical simulation and physical experiment. Influence law of dimension parameters of blank and auxiliary of forging forming quality is studied by numerical simulation. The lead specimen forming physical experiment of ratio of 1:15 validates the feasibility of bi-straight tapered cylinder forging forming process and finds that the results of numerical simulation are agreed well with the physical experiment.
