Abstract

Abstract: Ring radial-axial rolling technology is the best method to produce high quality large seamless ring. The metal flow behaviour of deformation areas of large ring radial-axial rolling process is studied. It is found that the fishtail pit of up-down surface of the ring section arises after the section passes through radial rolling area and that of in-out surface of the ring section arises after the section passes through axial rolling area. In order to gain better ring section, single radial rolling process is needed to remove the fishtail pit of in-out surface after double radial-axial rolling process. The study is very useful to constitute the process scheme of large ring radial-axial rolling.
