“…Specifically, the pattern of metal flow in particular grooves is particularly difficult to determine. In order to perform computer simulations of these processes, it is necessary to employ mathematical models that utilise the complete three-dimensional solution made by the finite-element method [1,2,[7][8][9]12,14], or models relying on the generalised flat state of deformation [4,5].…”

In order to continuously simulate multi-pass plate rolling process, a 3-D elastic hollow-roll model was proposed and an auto mesh-refining module with data passing was developed and integrated with FE software, Marc. The hollow-roll model has equivalent stiffness of bending resistance and deformation to the real solid and much less meshes, so the computational time is greatly reduced. Based on these, the factors influencing plate profile, such as the roll-bending force, initial crown, thermal crown and heat transfer during rolling and inter-pass cooling can be taken into account in the simulation. The auto mesh-refining module with data passing can automatically refine and re-number elements and transfer the nodal and elemental results to the new meshes. Furthermore, the 3-D modeling routine is parametrically developed and can be run independently of Marc pre-processing program. A seven-pass industrial hot rolling process was continuously simulated to validate the accuracy of model. By comparison of the calculated results with the industrial measured data, the rolling force, temperature and plate profile are in good accordance with the measured ones.

“…It is a rolling process in which material is shaped by three rolls in three directions, everyone of which is inclined to the others at 120º [1], [2]. Three-roll rolling process has various advantages such as easy flow control, small space requirement, and comparatively uniform deformation, etc.…”

Abstract.A three-roll rolling process is a significant technique in the production of wire rod, round bars and hexagonal profiles for structural applications. Better mechanical properties of wire rod, round bars and hexagonal profiles can be achieved due to large plastic deformation by the three-roll rolling process. Asymmetric rolling is a novel technique characterized by a kinematic asymmetry linked to the difference in peripheral speed of the rolls, able to introduce additional shear strains through the bar thickness. Physical simulation of shear strain, which is similar to that occurring in asymmetric three-roll rolling process, is very important for design of technology of producing ultrafine grain materials. Shear testing is complicated by the fact that a state of large shear is not easily achievable in most specimen geometries. Application of the shear-compression testing and specimen geometry to physical simulation of asymmetric three-roll rolling process is discussed in the paper. FEM simulation and comparison of the stress-strain state during shear-compression testing and asymmetric three-roll rolling process is presented. The results of investigation can be used to optimize the physical simulation of asymmetric three-roll rolling processes and for design of technology of producing ultrafine grain materials by severe plastic deformation.
