Abstract
the aim of the work is to create inductors for heat treatment of welded butt joints of railway and tram grooved rails. for heat treatment of welded butt joints of railway rails, the inductors were proposed, located opposite each other on the two sides of the rail. Investigation of local heating of railway and tram grooved rails with a frequency of 2.4 kHz showed that the inductors provide a uniform heating of cross-section rail elements, a low difference in the temperature between the surface and deep layers of the metal in the head of the rails and a decrease in heating time from the workshop temperature to the normalization temperature.
Keywords: rails, rail welded butt joints, heat treatment, induction heating, inductors
