The article presents a numerical analysis of the temperature and thermally stressed state of the ingot during continuous casting. In this paper have been built the numerical solution of the transient heat conduction equation using the finite difference method, enabling a detailed analysis of temperature field distribution in continuously cast ingots. These calculations formed the basis for modeling the thermally stressed state of the material, taking into account the interrelation of thermal, elastic, and creep deformations. Special attention is given to assessing damage accumulation during the cooling process. Damage diagrams were constructed and analyzed, illustrating the impact of cooling regimes on the development of internal defects. The obtained results contribute to optimizing technological parameters for ingot cooling during continuous casting, improving the operational properties of continuously cast billets, and preventing the formation of critical defects.
