【 摘 要 】

Asymmetric rolling is a technique used to control both the texture and the grain refinement of metallic materials. The aim of asymmetric rolling is to apply a large shear strain uniformly through the thickness of the plate, by maintaining a high degree of friction between the sheet and the rolls. It can be used to improve the formability of material. One of the advantages of asymmetrical rolling is that the rolling force and torque can be decreased. An economic and technological reason, in particular the longitudinally asymmetric rolling is very important to determine the optimum process parameters. The paper presents a method of simulating the asymmetric rolling process. This simulation is carried out to establish the main parameters of rolling particular asymmetric regime. The main goal is to establish a link between the peripheral speed of rolls, pressure and contact length.
