Abstract
The article deals with a particular case of stressed state of a body of a bimetallic rolling roll during heat treatment. To solve this problem, it is proposed to use a mathematical apparatus, which allows to determine the stress state of the roll cross-section during bending. Based on the data obtained, we conclude that the reduction of the roll band wall leads to an increase in the stress state in the peripheral layers of the roll and at the boundary of weldability. Based on the analysis of the dependencies, it is seen that the change in the mechanical properties of the working layer and the core materials significantly affects the difference between both the normal and shear stresses on the boundary of weldability of the working layer - the core.
Keywords: rolling roll, mathematical model, stress state, modulus of elasticity, tangential and normal stresses.
