Making "digital twins" for rolling processes and mill equipment should begin with the development of mathematical models of the deformation zone. The deformation zone of twohigh flat mill rolling have been studied in detail, relevant models are available in many academic papers. However, the same cannot be said about the most complex deformation zones in stands with multiroll gauge.

We study the process of tworoll screw rolling of billets made of stainless steel in order to estimate the influence of the feed angle on the plasticity of the metal of rolling billets. Pilot rollings were simulated by using the DEFORM software. In the computer simulation, the normalized CockroftLatham fracture criterion is used to predict the socalled Mannesmann effect (axial fracture of ...
