ABSTRACT
This paper presents an analysis of the results of the ring rolling process of EN AW - 7075 aluminium alloy using numerical modelling. The study of the rheological properties of the AW - 7075 aluminium alloy was carried out using the Gleeble 3800 metallurgical process simulator. The modelling of the ring rolling process in the experimental mill was carried out using the Simufact Forming programme based on the finite element method. Based on the analysis of the test results, the speed of the mandrel, the speed of the main roll, the temperature of the metal at the beginning and at the end of the rolling process were determined. The results of research were verified in an experimental mill.
