ABSTRACT
The article presents a comparison of the piercing process conducted in a two-roll Diescher mill and a three-roll mill. The comparative analysis was based on the numerical simulations of the aforementioned processes, obtained using Forge NxT 1.1. software. It was stated that the most favourable manufacturing method is skew rolling in three-mill rolling mills. The mills operating in this scheme are less energy-consuming, whereas the manufacturing time is 30% shorter.
