The paper presents an analysis of the problem of selecting the parameters of the model describing the heating process. Heating is treated as a part of the process of heat treatment of elements such as axles and shafts using a heat source in the form of an electric arc. For this purpose, an experimental stand was made and research was carried out to analyse the temperature in the control node. Cylindrical specimens with a constant cross-section made of medium carbon steel AISI 1045 were used as the test objects. A device using TIG technology was used as the heat source. Due to the heating of the element—its rotational movement—it was necessary to use a non-contact measuring device. The construction of the research stand is a representation of the developed industrial stand. In addition, calibrations of the non-contact measuring system were performed using a thermocouple system. Comparing the results obtained from the experiment and the numerical model showed a fairly high convergence of the adopted numerical parameters (the difference between the experiment and the numerical model did not exceed 6.5%). In addition, an analysis of the surface of the samples was performed for the occurrence of remelting by determining its roughness and waviness. |
