| Abstract Scope |
The main concerns of forming super-large rectangular ring are forming accuracy, rolling stability, uniformity of deformation and accordingly the distributed microstructure and related mechanical property of the rolled ring. In this paper, a rectangular ring with diameter of 9m is taken as an example, which is the bearing ring of a carrier rocket. To meet the requirements of formation and performance, the whole forming process, including multi-directional forging, punching, reaming and ring rolling is investigated step by step. Three multi-directional forging schemes are compared in order to improve the internal quality of ring billet. For the reaming process, four different reduction amounts per pass are designed to control the end surface quality of the reaming operation part. To refine grain and minimize the anisotropy of the rolled ring, the ring rolling process is divided into high temperature rolling and low temperature rolling, the feeding strategy of which are studied respectively. |
