Abstract

The paper presents results of numerical simulation of the asymmetric rolling process for band with shape ratio h0/D = 0.072 – steel grade S355J2G3. The study was conducted to determine the differences in the impact factor of different kinds of asymmetry on the band bending after leaving the deformation zone and the power parameters of rolling process. Introduction of single asymmetry, by varying the peripheral speed of the work rolls, does not have an effect on reduction of force parameters values. Based on the survey it was found that simultaneous introduction of second asymmetry, by varying the diameter of the work rolls, allows to lower rolling force and it also allows to obtain flat band after rolling process.

Keywords: Dual asymmetry, speed asymmetry, geometric asymmetry, plate rolling
