Investigation of 2-D Hot Ring Rolling Simulation and Effects of Different Parameters on Forming Process of Jet's Spool

The ring rolling process is widely used to manufacture seamless ring-shaped parts for automotive, aerospace and nuclear industry such as aero-engines and nuclear reactors parts. In addition, the savings in time, energy and material during the production of ring shaped parts have been instrumental in reducing the overall cost. Due to the complexity and high nonlinearity of the process, it is obviously difficult to investigate the process purely by analytical and experimental methods, more attention is paid to the finite-element method to explore and develop the advanced ring rolling technologies. In this research, simulation of hot ring rolling of titanium alloy (Ti6Al4V) has been investigated. For the sake of time, the effects of rolls dimension, their velocities and some assumptions in rolling process with two dimensional models were conducted. The results of 2-D and 3-D models might agree or disagree, depending on the key parameters. In this paper, according to the values of the key parameters, the 2-D models have been used as an appropriate case for simulation and analysis. The effects of some relaxing assumptions on ring rolling process, like material properties and guide rolls existence, have been studied. The results provide guidelines for hot ring rolling simulation of Ti6Al4V alloy.
