“…Increased requirements for safety and performance of structural elements operating in difficult conditions, lead to the necessity of their manufacture from the most perspective materials. Production of high-strength alloys is directly related to the various structural transformations that occur under certain temperature and speed modes [1][2][3][4]. Often the existence of desired structure is achieved by cooling of the material at a predetermined velocity [1].…”

The work deal with numerical modeling of the air cooling of cylindrical billet. The solution is carried out taking into account the dynamics of environmental air, radiation heat transfer, turbulence of the flow and conjugate heat transfer. The modeling process was realized in the accordance with a scheme of manufacturing of alloys with the structure of lower carbide-free bainite. A mathematical model has been developed by means of the finite-volume software Ansys CFX. The most effective mechanisms to control the cooling speed of the billet have been identified during numerical experiments.
