    Machines. Technologies. Materials., Vol. 11 (2017), Issue 2, pg(s) 51-52

    The development of new and modernization of existing methods of plate-rolling in order to obtain high-quality and competitive products is a promising task. This paper presents the results of a comparative analysis of the classical plate rolling technology and new technology, including rolling in relief rolls and workpiece alignment on a smooth barrel followed by rolling to the desired size. Comparison of these technologies was carried out with the help of computer simulation methods in finite element software package SIMUFACT FORMING together with a database of materials properties MATILDA. The analysis was conducted by parameters such as: the degree of elaboration of the workpiece, deformation scheme, the evolution of the microstructure. For comparison, the values of the stresses and deformations of the workpieces to be processed on existing and proposed technologies, studied the stress-strain state using the coefficient Lode-Nadai. Analysis results obtained in the course of the simulation allows to predict better quality plate production with the use of the proposed technology plate rolling.
