Popis: The main problem of induction hardening consists in obtaining the requisite hardness of the surface layers of parts. In hardening rolls by currents of commercial frequency the hardness and thickness of the hardened layer are determined by the speed of motion of the inductor, its power, and the intensity of the sprayer cooling. The choice of these parameters with the help of a full-scale experiment is a very expensive and laborious operation. For this reason it is expedient to determine the regimes of induction hardening with the use of numerical experiments. The present work is devoted to the creation of software for computing the hardness in induction hardening from the cross section of the roll. Since the hardness of the steel is determined primarily by the structural state that dependes on the temperature regime, the software should included the solution of problems of thermal conduction, determination of the structural state, and calculation of the hardness as such.
