Finite Element Method


Finite element analyses of rolling processes have been carried out for many years.
Most of the simulations focus on deformation of metal plates/sheets without taking into consideration flexibility of rolls and the machine frame.
In this case, we present a unique approach to simulation of rolling of thick plates where compliance of rolls and the complete structure of a roll leveler is taken into account.

This approach makes it possible to accurately predict shape distortion of steel plates and gives valuable, practical information on how to prevent shape defects in a rolled product.

In addition, roll leveling of steel plates after continuous casting, is analyzed.
This approach is universal and can be applied to other types of rolling processes.
a) Beam elements representing geometry of a roll;
b) Contact segments on a surface of each roll;
c) Rigid links connecting beam elementsf nodes and contact segments;
d) Steel plate described by 3/D solid u/p elements with elastic-plastic material properties;
e) Contact between rollsf contact surface and plate;
f) Frame structure is modeled by a grillage.
