Abstract

Under real rolling conditions, plastic strain is accompanied by inevitable uneven distribution of the metal movement velocities, strains and stresses both in height and width of the actual deformation zone of the rolled metal. With the simultaneous plastic strain of various metals, there is still a layered inhomogeneous strain, which is caused by the fact that at the same time in a plastic zone there are metals possessing different mechanical properties. The inhomogeneity of layered strain is one of the most important and complex problems of the theory of simultaneous plastic strain. A considerable number of works, has been devoted to the investigation of this problem, but many of the issues that we should deal with when developing the technology for the production of clad products remain unclear. In this article, the authors carried out a study of the process of rolling high cross-section ingots with cladding plates, using finite element modeling in the DEFORM software. Relationships are determined to take into account the strain inhomogeneity and the influence of various parameters on the depth of strain penetration into ingot
