Аннотация: The paper states urgency of the problem of determining stress-strain state of metals of the cladding layer and the main strip in production of three-layer bimetal: alloyed steel-constructional steel-alloyed steel. Temperature field of the main strip and cladding layer is given to calculate stress-strain state of metals of three-layer bimetallic strip. Initial data for calculating this stress-strain state are given. To assess the effect of coefficient of friction between cladding layers and the main strip on stress-strain state of metals in deformation zone, three values of it are taken. Geometric model is described for calculating stress-strain state and metal flow in deformation center of cladding layer. Characteristic lines and points of calculation are provided. Technique for solving the problem of determining stresses and flows in deformation focus is described by finite element method using ANSYS app. Regularities of flow of cladding layer’s metal along the length of deformation center and movement of the main strip of bimetallic ingot are given. Values of mutual displacement of layers of bimetallic strip are determined as a function of deformation degree of the cladding layer. And the recommendations are given on this degree to improve quality of a three-layer bimetal. Regularities of distribution of axial and tangential stresses in deformation center are presented for production of steel three-layer bimetallic strips in the unit of combined continuous casting and deformation. Stress state of the cladding layer’s metal in focus of cyclic deformation was estimated from the position of improving quality of three-layer bimetallic strips produced in such unit. © 2019 National University of Science and Technology MISIS.
