Abstract
The calculation of the deformation of a becoming hardened concast billet under the action of internal ferrostatic pressure
Incoming article date: 17.12.2018The article is devoted to the close studying of heat transfer and hardening of the ingot in the secondary cooling zone (further SCZ) in the continuous casting machine (further CCM), and also determining a stress-strain state of the ingot including continuously varying temperature field inside it in order to prevent the process of buckling the ingot by setting rollers in the center of the largest displacements and deformations and as a consequence of reducing the length of the roller section. This aim is achieved through the development of methods of calculation of the stress-strain state of the ingot in a CCM with a help of the temperature object decision, correct selection of the approximation model of the experimental data and the selection of finite element-based on the Lagrangian description of motion of a continuous medium and comparison the calculation results for multiple selected sections.
