In this study, the authors search for the universal inductor design to provide uniform local heat treatment of simple and complex profile disks, in particular, for the most demanded standard siz-es of truck diaphragm springs. New research data have been obtained for various sizes of metal disks. The influence of geometric, electrical and positional parameters on the temperature distri-bution of the product under consideration during its electromagnetic heat treatment was re-vealed. The dependence of temperature on the dimensions of the heated object, the number and length of the fingers of the diaphragm spring, the influence of the finger bend zone on the final temperature profile were studied too. The results of the research and
development work are aimed at reducing design costs for the manufacture of inductors for each standard size of truck diaphragm springs and at increasing the efficiency of the heating process by controlling the oper-ating mode.
