Abstract

The authors carried out a study on a new technology for producing billets on a combined continuous casting and deformation plant. The paper describes a method for producing three steel billets on the continuous casting and deformation plant. The problem statement is given, initial data and boundary conditions are stated to determine the stress-strain state of steel in the zone of cyclic deformation, when forming three steel billets from a continuously cast slab by the calibrated flat dies of the plant. The paper describes a procedure for solving the problem of elastoplasticity by the finite element method using the ANSYS package. It analyzes a non-stationary process of penetrating the continuously cast slab with the separating collars of the calibrated flat die, when producing three steel billets on the continuous casting and deformation plant. The results of calculating the penetration of the collar into the slab by 48 mm are given by the characteristic lines located on the contact surface of the calibrated flat die with the slab. The authors determined the regularities of the distribution of axial displacements and stresses in the deformation zone, when penetrating the continuously cast slab with the separating collars of the flat dies.

Keywords
