Abstract
Selection of heating mode, which provides an optimal combination of technological parameters to obtain the necessary structural and phase transformations of welded butt of high-strength railway rails, which is subjected to heat treatment, is a complex process that requires carrying out a large number of experiments with a significant consumption of time, labor, power and financial resources. To solve this type of problem, it is rational to use methods of mathematical and physical modeling, which are based on the use of mathematical models, numerical calculation methods and experimental data of physical modeling in determining key parameters of heat treatment process. For this purpose, based on the theory of similarity, a mathematical model of the process of heat treatment of small specimens was proposed, taking into account the interrelated properties and physical phenomena with the original study. A simplified model of the specimen is considered, on which the optimal heating conditions are tested and the properties of the weld metal subjected to heat treatment are investigated, after which the transition to specifying the conditions of heat treatment of the real welded butt of high-strength railway rails is carried out. This approach makes it possible to significantly reduce the resources in determining the optimal conditions of heating products of high-strength carbon steels, including butt welded joints of railway rails. 13 Ref., 5 Figures.
