Abstract
Results of computer simulation of variation of temperature and structural state and of formation of stresses in surface hardening of forming rolls heated by induction are presented. Two variants of surface hardening of rolls with heating by commercial-frequency currents (CFC) used at machine-building plants are considered, i.e., hardening with five-pass heating by CFC and hardening with one-pass heating by CFC and preliminary furnace heating to 500°C. The second variant of heat treatment is shown to be more efficient. [ABSTRACT FROM AUTHOR]
