FIELD: heat treatment of parts made in form of bodies of revolution from metal materials; cooling of monoblock wheels, tires, wheel discs and similar discs and rings such as railway wheels and tram wheels, gear wheels and sprockets.
SUBSTANCE: first, scale is removed from one and the same device by one and the same method to improve its mechanical properties and then mechanical properties are determined and reproduced through complex cooling performed in functional zone; cooling processes are different for different sections; parts are cooled at control or adjustment in "on-line" mode due to spraying or blowing-off by one cooling medium.
EFFECT: enhanced efficiency.
